The so-called fluoride toothpaste, as the name suggests, means that the active ingredient in toothpaste contains fluoride, generally this kind of toothpaste is considered to prevent dental caries functional toothpaste, so let's first understand why fluoride in toothpaste can prevent dental caries to a certain extent. Caries is the result of breaking the dynamic balance between demineralization and remineralization of hard tissue of teeth. Because of food residues or incomplete brushing, it can cause minerals in the teeth to dissolve and lose until cavities form. The fluoride in toothpaste can make the remineralization effect greater than the demineralization effect, so that dissolved mineral salts re deposited on the tooth, thereby preventing the development of dental caries. It's important to understand fluoride correctly! Because of this, fluoride began to appear in toothpaste. The amount of fluoride ion in toothpaste is generally 1000mg/kg, and a large number of clinical trials have shown that dental caries are reduced by about 20%-30%. If the mass fraction of 0.02% or 0.05% sodium fluoride is added to the gargle, caries can be reduced by 40%. Since the 1980s, the number of caries patients has decreased significantly, which is closely related to fluoride toothpaste. Therefore, it is certain that adding fluoride to toothpaste can reduce dental caries, but it is difficult to reliably assess the optimal dose of fluoride in toothpaste. At the same time, in the process of gradual use, the two sides of fluorine have also emerged. There are fewer patients with dental caries, but more and more patients with dental fluorosis, which is a side effect of fluoride. Dental fluorosis is just a warning of fluoride to people, and what is more frightening is that long-term intake of high doses of fluoride may lead to neurological diseases and endocrine system dysfunction! Fluoride enhances the acid resistance of dental calcium and inhibits bacterial fermentation to produce acid, thus strengthening bones and teeth and preventing dental caries. However, high concentration of fluorine is very harmful to the human body, and the light affects the development of teeth and bones, resulting in chronic fluorosis such as bone fluorosis and dental fluorosis, which makes the bone density strong and easy to fracture. We need to have a clear understanding of fluorine and fluoride, that is, fluorine is actually a toxic substance! Excessive fluorine is harmful to human health. At present, more than 20 provinces and cities in China belong to high-fluorine areas, and the use of fluoride toothpaste in these areas is tantamount to worse. Therefore, fluoride toothpaste is not can not be used, but can not be used as a common toothpaste every day. If long-term use leads to excessive fluorine, I am afraid it will backfire. Especially children, due to poor swallowing function, mouth wash is not complete, easy to swallow more toothpaste, resulting in fluoride poisoning or fluoride residue in the body. We must now have a clearer understanding of the advantages and disadvantages of fluoride toothpaste. Fluoride toothpaste in the prevention of tooth decay can indeed achieve a very good effect, but it is not 100%, and fluoride in the role of the human body at the same time the side effects are also very large, so we try to choose some healthy non-irritating ingredients in the daily toothpaste. However, if you want to prevent tooth decay, it is still necessary to change your lifestyle and use a toothpaste containing probiotic ingredients. Do the following three points, even without fluoride toothpaste, you can easily stay away from dental caries! 1. Eat a healthy diet: eat less or do not eat foods that are high in oil and sugar, as well as tobacco and alcohol that damage teeth. Even if you eat, it is especially important to gargle in time, especially for children to prevent dental caries. 2. Develop the habit of gargling or mouth containing probiotic powder after eating: most people have lunch at work or school, be sure to gargle after eating, if conditions are not allowed, you can choose oral Tiansan Qchangle capsule, which can help increase the number of beneficial bacteria in the mouth and reduce the generation of harmful bacteria; 3. Brush your teeth in the morning and evening and insist on using Tiansanqi Probiotic toothpaste: brush your teeth in the morning and evening in the correct way, clean the tooth surface and clean the food residue. Tiansanqi probiotic toothpaste is used when brushing teeth. This product contains Chinese herbs such as ginseng, Dendrobium officinale, camellia officinalis, Roxanthus roxanthus, sea bark, as well as Lactobacillus acidophilus, Bifidobacterium juvenis and Lactobacillus plantarum, etc. The use of plant fermentation products plays an effective role in dissolving tooth stain pigments, preventing the formation of dental plaque, refreshing breath, balancing bacteria and reducing the probability of dental caries. This not only plays a role in preventing dental caries, but also avoids the harm that the fluoride in the fluoride ointment may bring to human health. To sum up, when people buy toothpaste, they should choose products that use natural substances to do the active ingredients in toothpaste, so that this daily use of daily necessities can bring real health to our body, and will not increase other health hazards.

It is recommended that the baby begin to use fluoride toothpaste after the age of 1, but as a parent, it is inevitable to worry about the problem of fluoride poisoning, how to pick this fluoride toothpaste can be foolproof? This is because fluoride ions in fluoride can promote enamel development and remineralization, enhance tooth surface hardness and acid resistance, and inhibit bacterial fermentation to produce acid, so it can effectively play a role in preventing caries. Photo source: Cui Yutao Parenting Center The baby's teeth are often soaked in milk from the beginning of growth, and the careful degree of regular cleaning of the mouth and brushing is far less than that of adults, so the help of fluoride toothpaste is more needed.     In general, fluoride concentration to reach 0.05%, in order to have the effect of preventing dental caries, less than this amount can only be psychological comfort. However, too high is not good, if the concentration is more than 0.15%, it is not only easy to form dental fluorosis, but also may cause poisoning due to excessive intake of fluoride.   Therefore, China's latest toothpaste standards stipulate that the fluoride content of adult toothpaste is 0.05%~0.15%, and the fluoride content of children's toothpaste is 0.05%~0.11%.     Children will be subdivided into baby teeth, replacement teeth and permanent teeth according to the situation of tooth emergence. The fluoride content of toothpaste varies from time to time. During the deciduous tooth period, the child's teeth are small, enamel is underdeveloped, and mouthwash skills are not yet proficient, which is easy to swallow by mistake, so it is more suitable for toothpaste with low fluoride content. During the replacement period and the permanent period, the teeth are more mature and the food is more complex, so it is more appropriate to use a toothpaste with a higher fluoride content.   Photo source: Cui Yutao Parenting Center Doctors usually recommend toothpaste with 0.05% fluoride when you are 1 to 5 years old (around the time of baby teeth). From 6 to 11 years old (around the dental replacement stage), use a toothpaste with 0.1% fluoride, and older than 11 years old (around the permanent dental stage) can use a toothpaste with higher fluoride.   But each child's development rhythm is different, so the stage of the tooth is not fixed in the specific age, for example, some children began to replace teeth at the age of 5, then his replacement period is calculated from the age of 5, and some may only change teeth at 7, then his replacement period is calculated from the age of 7. Parents can combine their children's teeth, the mastery of gargling skills, and the degree of implementation of parental instructions, referring to the above recommended content to choose. Photo source: Cui Yutao Parenting Center After all, the national standard is a limit on the scope, then it means that within this range, it is relatively safe, and parents do not need to worry too much about the difference of 0.01%.   Generally speaking, as long as the child does not swallow toothpaste often (do not worry about swallowing occasionally, after all, poisoning needs to accumulate a certain amount), and will gargle fully, then in the case of using qualified children's toothpaste, there is no need to worry about excessive intake of fluorine.

There are many kinds of toothpaste on the market, so how should we choose? When choosing toothpaste, we should pay attention to its ingredients, especially whether it contains fluoride, such as sodium fluoride, sodium monofluorophosphate, stannous fluoride, etc., because these ingredients have an important role in preventing dental caries. 01 Understand the role of fluoride Fluoride is an effective ingredient in the prevention of dental caries, it can affect the formation of dental plaque, inhibit bacterial activity, and promote tooth surface remineralization. Specifically, fluoride can interact with hard tissue structures such as hydroxyapatite on the surface of teeth to form granular spherical substances such as calcium fluoride, which accumulate around the teeth and enhance the anti-caries ability of teeth. 02 Choose a fluoride toothpaste 1. Check the ingredient list: When purchasing toothpaste, you should carefully check the ingredient list to confirm whether it contains sodium fluoride, sodium monofluorophosphate, stannous fluoride and other fluoride ingredients. The content of these ingredients is usually clearly indicated in the ingredient list. 2. The difference between adults and children: a. adult toothpaste: The fluoride content of adult toothpaste is generally between 0.05% and 0.155%. When choosing, the appropriate amount of fluoride can be determined based on the individual's oral health and the advice of the dentist. b. Children's toothpaste: The fluoride content of children's toothpaste is relatively low, generally between 0.05% and 0.11%. This is because children's swallowing function is not fully developed, and high fluoride levels may pose health risks. 03 Consider other ingredients and functions In addition to fluoride, toothpaste may also contain a variety of other ingredients, such as rubbing agents, moisturizers, surfactants, thickeners, sweeteners, preservatives, etc. Each of these components has a different role, such as friction agent used to increase friction, remove pigment plaque on the tooth surface; Moisturizer keeps toothpaste moist; Surfactants help with foaming and cleaning. When choosing toothpaste, the following functions can be considered according to individual needs: l Anti-decay: As mentioned earlier, fluoride toothpaste is the first choice for preventing dental caries. Anti-allergy: For people with sensitive teeth, you can choose anti-allergy toothpaste containing potassium nitrate, strontium chloride and other ingredients. Whitening: If you want to remove the external pigments on the surface of the teeth (such as smoke stains, coffee stains, etc.), you can choose a toothpaste with whitening function, which usually contains calcium carbonate, silica hydrate, peroxide and other ingredients. 04 Precautions Avoid using the same toothpaste for a long time: long-term use of the same toothpaste may have a certain impact on dental health, it is recommended to change different brands and types of toothpaste regularly. Pay attention to the safety of toothpaste: ensure that the selected toothpaste meets national safety standards and has no harmful additives. l Appropriate use: When using toothpaste, the amount should be controlled to avoid excessive use of fluoride intake. For children, it is especially important to monitor the brushing process and prevent swallowing toothpaste.

Fluorine is one of the substances that exists widely in nature, and there are many interesting scientific stories about the discovery of fluorine, but that is not the focus of our discussion today. What I want to discuss with you today is a widely circulated rumor that fluoride toothpaste causes cancer.   Imagine brushing your teeth and hearing someone say, "You know what, don't use fluoride toothpaste, it causes cancer!" Do you ever get the shock of thinking you've been brushing your teeth for decades and almost spit out all the toothpaste in your mouth?     The more likely explanation for the origin of this statement is that some academic studies have explored the harm of excessive intake of fluoride to the human body, and concluded that it may cause "neurological and endocrine diseases and even cancer." Although these conclusions themselves are still controversial, but the "fluoride toothpaste causes cancer" argument is widespread. So what are the facts? In fact, the addition of fluoride to toothpaste to prevent caries was the biggest discovery of oral preventive health care in the 20th century. Numerous large-scale, credible studies have confirmed that the use of fluoride toothpaste is a safe, effective, and low-cost means of preventing dental caries. There has never been any study showing that using fluoride toothpaste causes an increased risk of cancer. Even if many people feel a little discomfort in the oral mucosa or skin around the mouth after using fluoride toothpaste, it is basically caused by other ingredients in the toothpaste, and human allergies to fluoride are extremely rare.     Will the fluoride toothpaste turn yellow? "Using fluoride toothpaste will turn yellow" is also one of the reasons why many people have concerns about fluoride toothpaste. The so-called yellow die that we are worried about, the corresponding medical term is dental fluorosis. The main cause of dental fluorosis is indeed due to the intake of too much fluorine during the growth and development stage, resulting in the development of tooth enamel is affected, and eventually the formation of chalky teeth with brownish yellow spots. Because this kind of tooth seriously affects the appearance, it will also make some people "talk about fluorine color change". In the definition of dental fluorosis, there are two key points that need to be paid special attention to: one is the "growth and development stage" and the other is "intake". In other words, he must have had too much fluoride in his stomach when he was less than 8 years old. The fluorine source that can meet this condition is generally drinking water, if the local drinking water treatment is not in place, the water contains too much fluoride, then in the process of drinking a lot of water for a long time fluorine will accumulate in the body, and eventually lead to dental fluorosis. In other words, if you are an adult, even if you drink water with too much fluoride, you will not cause dental fluorosis; If you do not eat fluoride in your stomach, but just hold it in your mouth for a while and spit it out, then it will not cause dental fluorosis. Fluoride toothpaste acts locally on the surface of the teeth, making the minerals in the teeth stronger and more resistant to corrosion, thus playing a role in preventing caries. Gargling after brushing can take away the fluoride in the toothpaste and will not cause excessive intake of fluoride. Speaking of which, some people will have such concerns - although gargling can take away most of the toothpaste, it is inevitable that you will swallow a little foam when brushing your teeth, and will it also cause excessive fluorine over time? The answer is no. For the fluorine concentration in fluoride toothpaste, the state has clear regulations, not more than 1500ppm (a concentration unit of measurement), that is, the fluoride content of 1 gram of toothpaste will not exceed 1.5 mg, the toothbrush is packed with toothpaste is less than 1 gram, and each person takes 3 mg of fluoride per day is safe. So as long as you do not swallow all the toothpaste you brush your teeth every day, brushing your teeth with fluoride toothpaste will not cause excessive fluoride and is absolutely safe.     Is it safe for people in high fluoride areas to use fluoride toothpaste? The high fluorine area, as the name suggests, is the area with high fluoride content in drinking water. So is it true that people living in these areas have dental fluorosis and can't safely use fluoride toothpaste? Apparently not. The division of high fluorine areas is very macro, as long as the drinking water in the province is high in fluorine, then the province is classified as a high fluorine area, in fact, there may only be a few townships or villages of water is unqualified. In recent years, China has invested a lot of financial and material resources to control water quality problems, and at present, basically as long as the tap water supplied by the water company is unified, there is no problem of excessive fluorine, so even if you live in the high fluorine area, there is no need to panic, fluoride toothpaste should be used. If the drinking water in your area does contain excessive fluoride, is it no longer acceptable to use fluoride toothpaste? Not really. Even if the fluoride content in drinking water is high, its concentration will not exceed 10ppm, and the medical community has recognized that the fluorine concentration below 500ppm is not a caries prevention effect. In other words, drinking more drinking water with excessive fluoride can not prevent dental caries, or rely on the high concentration of fluoride toothpaste, a short time to prevent caries. To take a step back, if the area is indeed due to drinking water problems caused by a large number of dental fluorosis, the normal use of fluoride toothpaste will not aggravate the situation of dental fluorosis, but also greatly reduce the incidence of dental caries; If you do not use fluoride toothpaste, the situation of dental fluorosis will not be relieved, but it is easy to become a mouth full of "worm teeth" dental fluorosis.     Is it safe for children to use fluoride toothpaste? People who put forward this problem, the main consideration is that children generally do not have a good grasp of the skill of gargling, will eat more toothpaste than adults, and in order to let children develop a good habit of brushing teeth, many children's toothpaste in the taste are modulate very sweet and delicious, which also leads to children will be more active to eat toothpaste.   Similar to adults, whether children will be poisoned by using fluoride toothpaste cannot be talked about without dosage. I've just done the math for you, and for adults, toothpaste is not toxic as long as it is not taken in whole bites. But children do have special characteristics, small weight, development, so we have to be more careful. The latest guidelines issued by the American Dental Association clearly point out that from the beginning of the child's first tooth, it is necessary to use fluoride toothpaste to brush, but pay attention to the amount of children less than 3 years old, the amount of each time is about the size of large rice; For children 3 to 6 years old, the amount used each time is about the size of soybeans. For this amount, gargling or gargling is no problem. ✓ Health knowledge "highlight" For families with children, be sure to place toothpaste out of reach of children to prevent children from swallowing it. Daily use of fluoride toothpaste, neither carcinogenic, will not become yellow mater, for adults and children, fluoride toothpaste is equally safe.

According to the "Healthy Oral Guide for Chinese Residents", brushing with fluoride toothpaste is the most effective way to prevent dental caries, but do not overdo it! In the latest national standard for toothpaste, children can use fluoride toothpaste with a fluoride content of 0.05% to 0.11% (that is, 500 to 1100 mg of fluoride per 1000g).   In order to prevent excessive fluoride caused by accidental swallowing of fluoride toothpaste, it is necessary to control the amount of toothpaste. Children under 3 years old should brush their teeth with children's fluoride toothpaste the size of a grain of rice every morning and evening, and use gauze to remove the remaining toothpaste after brushing. Children 3-6 years old should use a pea-sized children's fluoride toothpaste and rinse properly after brushing to reduce swallowing and residue.   Children under 6 years of age should use fluoride toothpaste under parental supervision and guidance, and fluoride mouthwash is not recommended. Infants under the age of 3 should try to choose unscented toothpaste, because at this stage the baby's swallowing response is not fully developed, and sweet toothpaste is easy to lead to active swallowing. The most important thing is that toothpaste only plays an auxiliary role in the brushing process, and is not a panacea for oral problems, and careful and correct "brushing" is the key to dental care.   It is best to brush from the right and the left hand is best to brush from the left The bristles are placed at an Angle of 45 degrees, where the teeth meet the gums Small amplitude water tremor when brushing 2 to 3 teeth in a group from front to back, from back to front brush ▽ The inside of the teeth should also be brushed The occlusal surfaces of the teeth should also be brushed Also brush your tongue Note: Brush for at least two minutes each time

Should I buy fluoride or fluoride-free toothpaste for my baby? Today we're going to talk about choosing toothpaste for your baby. Is toothpaste better with or without fluoride? Regarding dental care, parents often pay more attention to the choice of toothpaste, but there are too many statements about toothpaste, especially some sales staff will directly tell you that "fluoride toothpaste is not good, we are not fluoride." Fluoride is an essential trace element in human body. Fluoride toothpaste is an effective way to prevent dental caries. If the human body is deficient in fluoride, symptoms such as dental caries (cavities) and osteoporosis will occur. However, if the human body takes too much fluorine for a long time, the light will produce dental fluorosis (that is, macula), and the heavy will lead to fluoride poisoning. This makes more parents uncertain, how to control bad? The American Dental Association (ADA) and the American Academy of Pediatrics (AAP) both recommend that children should use fluoride toothpaste no larger than a grain of rice before the age of 3, and children between the ages of 3 and 6 should use fluoride toothpaste the size of a pea. (The left side is the amount before the age of 3, the right side is the amount after the age of 3) How to choose toothpaste? The new national standard for fluoride content stipulates that the fluoride content in children's fluoride toothpaste should be between 0.05% and 0.11%. Therefore, when buying, parents should look at the fluoride content of toothpaste ingredients. Many children's toothpastes label fruit flavors such as "strawberry" and "orange", and some may even be sweet. This can easily lead to some children will toothpaste as something to eat, and the child will not spit it out naturally. When the child thinks this is delicious and tastes good, there may be a risk of ingestion. It is not appropriate to use multi-foam toothpaste. Toothpaste is generally divided into three types: multi-foam, medium bubble and less bubble. The amount of foam depends on the amount of soap contained. The soap content of multi-foam toothpaste is more than 18%, and the soap is easily decomposed into caustic soda or ester acid in the oral saliva, which not only stimulates the oral mucosa, but also destroys the yeast enzyme in the saliva. In addition, the soap content is large, which reduces the friction on the tooth surface correspondingly, and affects the cleaning effect. Therefore, it is not appropriate to choose frothy toothpaste for your baby. When does dental care start? When the baby's first tooth is found, caries may soon develop, and parents need to pay attention to oral care. Wipe and clean daily with a clean damp cloth or fingertip brush. As more teeth erupt, switch to a small, soft toothbrush. The Centers for Disease Control and Prevention (CDC) recommends that children start using fluoride toothpaste at age 2. Supervise or help your baby brush his teeth twice a day until he can brush his teeth properly without parental help. For babies who have not learned to gargle and spit out, parents can teach their babies to brush their teeth with water. In addition to using toothpaste, it is necessary to develop good dental habits When you find your baby's first teeth, brush them with a gentle baby toothbrush or wipe them with gauze. Avoid letting your baby sleep while drinking milk, day or night; The goal of brushing is to thoroughly clean each tooth, from top to bottom, inside to outside, once in the morning and once in the evening. Try to let your baby eat less sugar, and brush his teeth after every sugar; Minimize your baby's consumption of any sugary liquids; Babies who are used to using bottles should stop using bottles when they are 1 year old. See your dentist regularly. Babies who have teething before the age of 1 should see a pediatric dentist before the age of 1. Develop good dental habits should be picked up from a young age, do not think that there are permanent teeth after the baby teeth are lost, and there are opportunities. The decay of deciduous teeth and the destruction of dental crowns lead to the deterioration of the oral environment, which makes the inherited permanent teeth susceptible to caries, especially the adjacent permanent teeth.

Toothpaste is a paste applied to the surface of human teeth in the way of friction, with the main purpose of cleaning. Friction agent is the main raw material of toothpaste. When brushing teeth, the friction agent in toothpaste is rubbed on the tooth surface through the toothbrush bristles to achieve cleaning and removing tooth stains. What is fluorine?   "Fluorine" is a trace element, mainly with drinking water into the human body. It is a double-edged sword, moderate intake of fluoride can prevent caries; However, if the intake is too much, it will lead to chronic fluorosis and "fluorosis", which is manifested as tooth discoloration or even rough surface and defect, and serious fluorosis will cause systemic bone calcification and other lesions. In addition to ingestion through drinking water, fluorine can also be ingested through breathing, and people living in coal-producing areas are prone to fluorosis because of the release of fluorine during the burning of coal. What is fluoride toothpaste? Fluoride toothpaste refers to the addition of fluoride, such as sodium fluoride or fluoride salt, to the toothpaste formula. Fluoride binds to minerals on the surface of the tooth to form a protective fluoride layer that prevents the tooth from being eroded by acids and reduces the risk of dental caries.     What are the benefits of fluoride toothpaste to inhibit cariogenic bacteria: Fluorine can inhibit the growth of cariogenic bacteria and neutralize polysaccharide. The occurrence of caries is closely related to the bacteria attached to the tooth surface. The experiment showed that fluoride concentration could inhibit the storage of polysaccharides in the cells of S. cariogens. Intracellular polysaccharide is the nutrient of bacteria, its lack will affect the metabolism, growth and reproduction of bacteria. Fluorine can also enter the plaque through two ways of dental tissue outward or through saliva inward, inhibiting the glycolysis into organic acid enzymes, thus reducing the formation of organic acid, demineralization of hard tooth tissue is suspended, and the prevalence of caries is reduced accordingly.   Repair tooth enamel After the use of fluoride toothpaste, the fluoropapatite formed in the outer enamel can be maintained for a long time. In the early stage of enamel demineralization, the surface enamel crystal changes from hydroxyapatite to fluoropapatite which is more resistant to acid dissolution. Its strong crystallization surrounds the original hydroxyapatite crystal and prevents it from continuing to dissolve. When the concentration of fluoride ions in the mouth continues to maintain a relatively high concentration, fluorine can reduce the dissolution of hydroxyapatite, showing the effect of repairing tooth enamel, and can form an ion transport barrier, increase the concentration of calcium and phosphorus ions in the mouth, and then promote the remineralization of tooth enamel, and participate in the reaction of enamel mineralization and remineralization, playing a beneficial role.   Can children use fluoride toothpaste? Fluoride can only cause harm to the specific structure of teeth during development. Generally, only children who live in high fluoride areas for a long time before the age of 6 to 7 years will have fluorosis. Children over the age of 7 do not develop dental fluorosis even if they move to high fluoride areas. For children younger than 2 years of age, the use of fluoride toothpaste is not recommended because their swallowing reflex is not fully developed. For children who have been able to complete the mouth movement, the use of fluoride toothpaste is safe and beneficial, but children under the age of 6 should be supervised by an adult to urge them to spit out the toothpaste foam in time. In addition, for children in non-high-fluorine areas, it is also recommended to use "fluoride" for caries prevention, the specific way is to go to the hospital every six months to "fluoride" caries prevention treatment, it is not recommended that parents buy their own fluorine-containing preparations for children to eat or apply     How to use fluoride toothpaste correctly The application of fluoride can be divided into systemic application and local application. Systemic applications include: drinking water fluoridation, salt fluoridation, milk fluoridation, fluoride tablets, fluoride drops. Local applications include: fluoride toothpaste, fluoride mouthwash, local application of fluoride, fluorine coating, fluorine foam, fluorine gel, etc. The most common use of fluoride in our daily life is the local application of fluoride toothpaste and oral fluoride. In terms of usage and dosage, it should also be divided into adults and children, especially infants and toddlers, which need special attention. Adult: Toothpaste is a preparation to assist in brushing teeth, which can enhance the friction of brushing teeth, help remove food debris, soft dirt and plaque, help eliminate or reduce bad breath, and make breath fresh. Adults only need to use about 1 gram (about 1 cm in length) of paste each time they brush their teeth. If other active ingredients, such as fluoride, antibacterial drugs, control calculus and anti-sensitivity chemicals, are added to the toothpaste paste, they have the effect of preventing caries, reducing plaque, inhibiting calculus formation and anti-tooth sensitivity, respectively. Children: Fluoride toothpaste has definite effect on preventing caries. Preschool children generally gargle and spit out foreign bodies in the mouth, so children's fluoride toothpaste can be used to brush their teeth, but the amount of each time is the size of a pea, and under the supervision of parents or teachers to prevent swallowing. It is recommended to use toothpaste with a fluoride content of 500 PPM between the ages of 1 and 5 (children who do not have the ability to gargle fully before the age of 3 should prevent accidental swallowing and avoid excessive swallowing); From 6 to 11 years old, use a toothpaste with a fluoride content of 1000ppm, and older than 11 years old use a toothpaste with a fluoride content of 1500ppm. Infants and young children: Recommendations and guidance on the use of fluoride toothpaste for infants and young children aged 6 months to 3 years, after the first baby tooth eruption, parents should use fluoride toothpaste to brush their children's teeth twice a day. To ensure safety and effectiveness, it is recommended that infants and young children aged 0 to 3 years use 500 to 1100 mg/kg fluoride toothpaste, the size of a grain of rice (15 to 20 mg) each time, and use gauze to remove the remaining toothpaste in the mouth after brushing. Recommendations and guidance for the use of fluorine-containing coatings in infants and young children aged 0 to 3 years According to the results of the risk assessment of caries in infants and young children, from the first tooth eruption, a personalized local application of fluoride can be performed by a professional to prevent caries. It is recommended that infants with moderate or low risk of caries should use fluorine-containing coatings (fluorine-containing mass concentration of 0.10-2.26 mg/L) twice a year. For infants and young children at high risk of caries, fluoride is recommended four times a year. Fluorinated foams, fluorinated gels and fluorinated mouthwashes are not recommended for infants and young children under 3 years of age.

According to the definition of the national standard "Toothpaste (GB/T 8372-2017)", toothpaste is a paste consisting of friction agent, moisturizer, thickener, blowing agent, aromatic agent, water and other additives as the main raw materials. Rubbing agent, moisturizing agent and thickening agent are the top three raw materials of toothpaste. 1. Abrasive agent refers to the solid raw material component in the toothpaste that can work together with the toothbrush to erase soft dirt on the surface of the tooth and reduce foreign substances such as tooth stains, dental plaque and dental calculus. Friction is one of the main components of toothpaste, generally insoluble in water powder solid, particles and texture moderate, do not damage the enamel and dentin. The commonly used raw materials that can be used as toothpaste friction are natural calcium carbonate, calcium hydrogen phosphate dihydrate (calcium hydrogen phosphate dihydrate), silica hydrate (silica), light calcium carbonate, aluminum hydroxide, calcium hydrogen phosphate (anhydrous calcium hydrogen phosphate), etc. 2. Humectant agent is a liquid raw material ingredient used in toothpaste to maintain the moisture of the paste, maintain the fluidity of the paste, and reduce the freezing point of the paste, so as to facilitate the production, processing and use by consumers. Moisturizer is one of the main ingredients of toothpaste, generally polyols, can make the paste to maintain softness and fluidity, easy to pipeline transportation and filling processing; During the shelf life of the toothpaste, it can keep the paste not dry, unchanged hard, and does not affect extrusion from the hose; Reduce the freezing point of the paste to prevent the loss of proper consistency and solid-liquid separation when it melts after freezing. Common raw materials used as toothpaste moisturizer are glycerin, sorbitol solution (sorbitol), propylene glycol, polyethylene glycol, etc. 3. Thickening agent, also known as adhesives and adhesives, is a raw material component that disperses and expands in the liquid phase of toothpaste to form a stable colloid to suspend the solid phase of toothpaste and prevent the separation of the solid phase and liquid phase components in toothpaste. Thickening agent is one of the main ingredients of toothpaste, there are three types of commonly used: one is organic synthetic glue, such as cellulose glue (sodium carboxymethyl cellulose), hydroxyethyl cellulose, carbomer (carbo resin); One is natural plant gum, such as xanthan gum (Han sang gum), hydroxypropyl guar gum, crepe carrageenan (carrageenan); There is also an inorganic adhesive, such as thickened hydrated silica (silicon dioxide), colloidal aluminum magnesium silicate and so on.

In the face of a wide range of toothpaste shelves, are you ready to pick up, or choose your own brand, or "pick a moderate price"... Friends who have difficulty choosing should be more aware of the pain of this. First of all, we understand that the ingredients of toothpaste mainly include basic ingredients and functional ingredients. The basic ingredients are all toothpaste, but some ingredients and content are different, and the basic role of toothpaste (auxiliary cleaning) has little impact. Therefore, the essence of choosing toothpaste is actually to choose some effective ingredients of the toothpaste you need according to your own needs!   1, contains "fluoride" toothpaste   Toothpaste contains fluoride, such as sodium fluoride and sodium monofluorophosphate, which helps prevent tooth decay by remineralizing the surface of the tooth. Fluoride toothpaste is recommended for everyone, even children.   2. Whitening toothpaste   In fact, most of the toothpaste on the market is difficult to whitening effect, can only remove the colored substances attached to the tooth surface (external staining), such as tea stains, smoke stains and other external staining of the tooth surface. Toothpaste containing "silica hydrate", which belongs to the rub in toothpaste, can be used to clean the pigment and plaque attached to the surface of the tooth. Or "sodium bicarbonate", which can break down the mechanism of polysaccharides, breaking down plaque, making it loose and easy to brush off when brushing. Please do not forget that the original purpose of toothpaste is to use with brushing teeth, better prevention of dental caries and periodontal disease, think of the therapeutic effect, is not advisable, especially the following oral conditions, it is recommended to seek medical treatment. 1. Observe whether there is redness and puffiness at the edge of your gums, and find that teeth are redness and puffiness are serious, and gingival bleeding occurs when brushing teeth, then it is mostly periodontitis. 2, in the diet can also be judged, if eat cold, hot, sour, sweet food, teeth will produce pain, then it is the reason of periodontitis, it is recommended to let the doctor check. 3. In addition, if the gums shrink significantly, the gaps between the teeth become larger, the teeth shake, and there are phenomena such as bad breath, it is basically periodontitis.

In Europe, the content of hydrogen peroxide in oral products (toothpaste, mouthwash, whitening strips, etc.) must not exceed 0.1%. Whitening products with a concentration of 0.1-6% can only be used by dentists; Or the first time is supervised by a dentist, and the consumer must use it on his own; However, people under the age of 18 are not allowed to use these products. In China, it is generally believed that the hydrogen peroxide content of toothpaste should not exceed 3% (in terms of the presence or release of hydrogen peroxide), more than that no longer belongs to the traditional sense of toothpaste. In the domestic whitening toothpaste market, phytic acid and its sodium salt (sodium phytate) are used as whitening ingredients. Phytic acid, also known as inositol hexaphosphate, is an organic phosphate compound extracted from plant seeds. Chelate with the tartar complex that adheres to the tooth space or surface to form a water-soluble chelate. Toothpaste containing this ingredient makes stains more likely to come off when brushing. The compound of sodium phytate and pyrophosphate is used as whitening ingredient in China. The use of sodium phytate can refer to the standard "QB_T 5222-2018 oral cleaning care products for toothpaste sodium phytate". Other whitening ingredients: hydroxyapatite is the main inorganic components of bones and teeth, and the content of hydroxyapatite in human tooth enamel is about 96%, which has excellent biocompatibility and bioactivity, and has good effects on tooth mineralization, desensitization and whitening. Can prevent dental caries, less plaque, promote gingivitis healing. It can also be used as a toothpaste rub, which will not damage the tooth enamel, but also make the teeth whiten, prevent and treat periodontal disease, make the enamel surface recrystallization (remineralization), and the tooth surface shine. Swipe to see more Fluoride, a common ingredient in anti-caries toothpastes, speeds up the tooth repair process, reduces acid production by inhibiting bacterial growth and interfering with bacterial enzyme activity, and helps reinject minerals into tooth enamel. According to the "Healthy Oral Guide for Chinese Residents", brushing with fluoride toothpaste is the most effective way to prevent dental caries, but do not overdo it! In the latest national standard for toothpaste, children can use fluoride toothpaste with a fluoride content of 0.05% to 0.11% (that is, 500 to 1100 mg of fluoride per 1000g).   Part 2 Standard for the use of toothpaste ingredients In 2008, the China Oral Cleaning and Care Products Industry Association drafted and issued the national standard "Specification of Raw Materials for Toothpaste (GB 22115-2008)", which has certain management and constraints on the preservatives, colors and prohibited ingredients used in toothpaste (1,466 prohibited components and 39 restricted components). In 2023, Article 9 of the "Measures for the Supervision and Administration of Toothpaste" issued by the General Administration of Market Supervision has made requirements for the management of raw materials used in toothpaste, and the toothpaste filing person shall choose raw materials that meet the requirements of laws, regulations, mandatory national standards and technical specifications for toothpaste production, and be responsible for the safety of the toothpaste raw materials used. When the toothpaste recordholder makes the record, it shall clarify the source of raw materials and relevant information about raw materials safety through the record information service platform.   Toothpaste new raw materials related regulations New raw materials/registration   It is worth noting that in the "Measures for the Supervision and Administration of Toothpaste" it is mentioned that the natural or artificial raw materials used in toothpaste for the first time in the territory of the People's Republic of China are new raw materials for toothpaste.   The new raw materials of toothpaste shall comply with the relevant provisions of the management of new raw materials of cosmetics, and the new raw materials of toothpaste with anti-corrosion, coloring and other functions shall be registered by the State Drug Administration before they can be used; Other new toothpaste raw materials to implement the record management, and the implementation of safety monitoring system, has been registered, completed the record of new toothpaste raw materials to implement safety monitoring system, safety monitoring period is 3 years. The new toothpaste raw materials that have no safety problems after the expiration of the safety monitoring period are included in the used toothpaste raw materials catalog formulated by the State Food and Drug Administration.   Toothpaste as an essential daily consumer goods, enterprises should be careful about the use of toothpaste raw materials, must strictly abide by the relevant provisions of the management of new raw materials of cosmetics, to ensure the quality and safety of toothpaste, to protect the health of consumers.

Recently, I searched for toothpaste ingredients in various apps because I chose toothpaste. But as an illiterate, also do not know what others say is right, blindly follow it. For the convenience of future purchase reference, sort out this memorandum and put it here. The ingredients of toothpaste include rubbing agent, foaming agent, thickening agent (stabilizer), moisturizing agent, preservative, aromatic agent, active additive and color essence. The friction agent calcium carbonate is cheap and has strong cleaning power, but it will damage tooth enamel, reduce the caries prevention of fluoride, and accelerate tooth wear. The foaming agent sodium dodecyl benzene sulfate (sodium coco sulfate, sodium lauryl sulfate, sodium lauryl sulfate SLS) can stimulate the oral mucosa, induce and aggravate oral ulceration, and cause allergic reaction of respiratory system. The raw material glycol used to make the thickening agent polyethylene glycol is highly toxic, and polyethylene glycol may be mixed with ethylene glycol that is not completely converted during the production process, resulting in toxicity. Hydroxyphenylate, hydroxyphenylate and other paraben lipid preservatives may stimulate allergic babies, have an impact on human estrogen levels, it is recommended to avoid. Benzyl alcohol is both a preservative and an essence, one of the 26 essence allergens banned in the EU. Triclosan TCS is a low-toxicity spectrum antimicrobial agent, stimulating and affecting endocrine, long-term use is easy to cause thyroid homeostasis to be broken, induce metabolic disorders, cardiac toxicity. It may combine with residual chlorine in drinking water to produce carcinogens, and may also destroy intestinal flora. Titanium dioxide (titanium dioxide, CL77891, Titandioxid, Titanium dioxide) is banned in German daily chemical products. Long-term exposure of chlorxylenol PCMX and benzoxonium chloride BET destroys intestinal flora. Tranexamic acid is a clotting agent. Hydrogen peroxide (hydrogen peroxide, H2O2), hydrated silicon oxide, CL74160, CL74269, etc., are bleach and coloring agents that irritate gums and oral mucosa. Buffering agents are phosphoric acid, pyrophosphoric acid, carbonic acid, sodium salt of silicate, sodium hydroxide (caustic soda), etc., to adjust the acid-alkaline toothpaste, to strictly control the proportion, to prevent excessive alkaline damage to oral mucosa. Other ingredients to avoid include: aspartame, benzalkonium chloride BAC... Ingredients that have not been widely Diss: friction: aluminum hydroxide, calcium phosphate, calcium hydrogen phosphate, silica hydrate, anhydrous silicate humectant: sorbide (sugar) alcohol, propylene glycol, glycerol (glycerol) Aroma: food flavor Anti-caries: sodium fluoride, potassium monofluorophosphate, stannious fluoride antibacterial anti-inflammatory: zinc citrate, trichlorohydrophenyl ether copolymer, tocopherol Anti-sensitivity: Potassium nitrate, strontium chloride hexahydrate, paeonol, strontium-based whitening: sodium pyrophosphate, sodium phytate foaming agent: sodium lauryl sarcosinate, cocamidepropyl betaine, alkyl glycoside, lauryl glucoside Preservatives: sodium benzoate, sorbate, propionic acid and its salts, p-hydroxybenzoate thickening agent (stabilizer) : Carboxyl (suo) methyl cellulose (sodium), hydroxyethyl cellulose (sodium), colloidal silica roughly looked at a few toothpaste bought before: the higher price of Kao tooth care toothpaste, Colgate Himalayan rose salt toothpaste friction is actually cheap calcium carbonate; The foaming agent of Shuke enzyme toothpaste, cold acid line anti-sensitivity toothpaste, DARLIE Holai Tea Bihealth First Tea white peach flavor toothpaste is sodium lauryl sulfate, the latter has CL77891...... Tired. It took a long time to find one that did not use sodium lauryl sulfate as a foaming agent - Liangneedle tea fragrance toothpaste (Jasmine Longjing type), its foaming agent is sodium lauryl sarcosinate, but there is benzyl alcohol. PASS. It may be difficult to find the ideal ingredient of toothpaste according to this memo, so buy small tubes and replace them frequently. Especially remind yourself not to stock up on the same model.

01   Chemical composition in toothpaste Toothpaste is a complex mixture. Basic toothpaste is usually composed of friction agents, humectants, surfactants, thickeners, sweeteners, preservatives, active additives, and similar pigments. Some toothpaste in life are special toothpaste. Some toothpaste are fluoride toothpaste, which contain active fluoride and can prevent tooth decay. Chlorophyll toothpaste added with chlorophyll has a certain effect on preventing gingival bleeding and oral odor. The medicated toothpaste will add various drugs to the toothpaste, and its functions are generally targeted, such as relieving gum bleeding, oral odor, and tooth sensitivity.   02   Main ingredients in toothpaste Friction agent It is composed of calcium phosphate, calcium carbonate, aluminum hydroxide, silicon dioxide, titanium dioxide, etc. The most basic ingredient in toothpaste is used to remove various kinds of dirt on the tooth surface and enhance the cleaning effect of tooth brushing. Common friction agents include calcium carbonate, calcium hydrogen phosphate, and aluminum hydroxide. Calcium carbonate has certain damage to the enamel, while aluminum hydroxide and calcium phosphate are relatively high-quality friction agents. The difference in particle size and treatment process of friction agents is also one of the reasons for the difference in the price of toothpaste.   Buffer Buffer is mainly composed of phosphoric acid, pyrophosphoric acid, carbonic acid, sodium silicate, sodium hydroxide, etc. The main function of the buffer is to adjust the alkaline substances such as the acidity and alkalinity of toothpaste, which can enhance the stability of teeth. However, the amount of this buffer should be well controlled because it is harmful to the oral mucosa.   Humectant Humectants mainly include water, sorbitol, propylene glycol, and glycerin. The ingredients of moisturizing agents seem to be very "chemical," but they are all edible, non-toxic, and harmless ingredients. The humectant is used to make the solid and liquid of the toothpaste dissolve, and also make the mouth of the toothpaste not easy to dry so that the brushing experience is better. 03   Children & adults' toothpaste difference When we were young, our parents would buy children's toothpaste for us. This toothpaste was sweet when brushed, and there were many flavors, such as strawberry and peach. However, when we grew up, our parents began to buy adult toothpaste for us. This toothpaste is not only not sweet but also hot, cool, and exciting when brushed into the mouth, which many children cannot accept. So what is the difference between children's toothpaste and adults' toothpaste? First, children's toothpaste tastes sweet, but it is actually less sweet. Children's toothpaste generally uses xylitol, while adult toothpaste uses lactose. Second, children's toothpaste is generally fluoride free. Because children can easily eat toothpaste by mistake, if they swallow fluoride, they may have stomach pain, and even affect the development of the teeth bones. Third, edible essence is used in children's toothpaste, while essence is used in adult toothpaste. Compared with children's toothpaste, the composition of children's toothpaste is healthier.   04   How does toothpaste protect teeth First of all, toothpaste can basically clean teeth. It can clean food debris and dental plaque. This may seem simple, but it is crucial. If there are food fragments left in our mouth, it will not only cause bad breath but also lead to the multiplication of bacteria and tooth decay. Second, the general adult toothpaste contains fluoride. Although fluoride is a chemical substance, it can effectively strengthen teeth. The hair foaming agent in the toothpaste can also have a better cleaning effect on the teeth. After brushing the teeth, the mouth will be more refreshed. In addition, toothpaste contains anti-inflammatory and bacteriostatic substances, rich in vitamin C, and has a certain whitening effect on teeth.

Chemical ingredients in toothpaste Toothpaste is a complex mixture, and the basic toothpaste is usually composed of rubbing agents, moisturizers, surfactants, thickeners, sweeteners, preservatives, active additives, and color flavors. Special toothpaste refers to toothpaste with special properties. Fluoride toothpaste with active fluoride can prevent dental caries; The addition of chlorophyll to the chlorophyll toothpaste can prevent gum bleeding and bad breath. Medicated toothpastes add various drugs to toothpaste, which can relieve bleeding gums, bad breath and sensitivity to dentin.   The main ingredient in toothpaste   1. Rub It is composed of calcium phosphate, calcium carbonate, aluminum hydroxide, silicon dioxide, titanium dioxide (titanium dioxide), etc. The most basic ingredient in toothpaste is to remove all kinds of dirt on the surface of the teeth and enhance the cleaning effect of brushing.   The commonly used friction agents are calcium carbonate, calcium hydrogen phosphate and aluminum hydroxide. Among them, calcium carbonate has certain damage to tooth enamel, and aluminum hydroxide and calcium phosphate are relatively high-quality friction agents. The particle size of the friction agent and the different treatment process are also one of the reasons for the price difference of toothpaste.   2. Buffer It is composed of phosphoric acid, pyrophosphoric acid, carbonic acid, sodium salt of silicic acid, sodium hydroxide (caustic soda), etc. The main function of buffer is to adjust the acid-alkaline alkaline substance of toothpaste, which can enhance the stability of toothpaste, but it is necessary to strictly control the proportion of ingredients in toothpaste, so as not to damage the fragile oral mucosa because of excessive alkaline.   3. Moisturizer It is mainly composed of water, sorbitol, propylene glycol and glycerol (glycerol). The ingredients of humectants are edible or non-toxic and harmless ingredients, which are used to dissolve the toothpaste solid and liquid phase, and also make the toothpaste tube not easy to dry out. The addition of humectants provides us with a better brushing experience. Auxiliary component   Auxiliary ingredients are non-necessary ingredients, that is, substances that are not necessarily contained in toothpaste, and the addition of different ingredients makes toothpaste have more effects and effects. The special ingredients in the new functional toothpaste have great advantages over the traditional toothpaste, but many of them have advantages and disadvantages for the mouth, and should be selected according to individual needs.   Here are some common toothpaste ingredients: 1. Blowing agent Sodium dodecyl sulfonate (sodium lauryl sulfate) and other surfactants. Foaming agent can emulsify, decompose the oily residue in the mouth, has a strong cleaning and descaling ability, and can also make users feel the brushing effect more intuitively. However, such substances can stimulate the oral mucosa, so manufacturers will strictly control the amount of addition, and will also advise to avoid accidental ingestion.   2. Thickener Carboxymethyl cellulose (sodium), hydroxyethyl cellulose (sodium), colloidal silica, etc. Also called stabilizer, it regulates the fluidity and stability of toothpaste and increases the taste and experience of brushing.   3. Food coloring Food grade coloring added to toothpaste. In the past, the color of toothpaste was mainly blue and green, giving people the impression of whitening and green environmental protection, but now people are more rational to look at the problem - importantly, research shows that organic pigment molecules will attract microorganisms and shorten the shelf life of toothpaste, so now pure white toothpaste accounts for the majority, and color stripes and particles are gradually becoming less.   Step 4: Preservatives Benzoic acid, sorbic acid, propionic acid and its salts, p-hydroxybenzoates, etc.   The toothpaste itself should be clean and pollution-free, so trace preservatives that can destroy the structure of bacterial cells will be added to the toothpaste. Toothpaste that has been left for a long time may form mildew of different colors and cannot be used anymore.   5. Flavor A compound derived from plant essential oils and some aromatic odors. Flavors mask bad breath, and fragrance ingredients are helpful in social situations but not therapeutic. In fact, bad breath can come from microorganisms, and the best way to get rid of bad breath is to keep your gums healthy, maintain oral hygiene, and pay attention to your diet.   Step 6: Sweeteners In order to improve the taste of toothpaste, a small amount of saccharin is added to the toothpaste. Because glycerin, which is used as a wetting agent, also has a sweet taste, the dosage of saccharin is generally 0.01% to 0.1%. Xylitol can also be used as a sweetener.   7. Natural active ingredients Green tea extract, coconut oil, plant essential oils, Chinese herbal ingredients, and extracts of certain flowers. Green tea and other plant natural ingredients are friendly to the oral mucosa cells, there will be some such as "fire" regulatory effect, but it is difficult to play the effect of treating a disease, should not be over-emphasized, symptoms should be timely medical treatment, should not over-rely on some ingredients in toothpaste.   8. Spices The main flavor used in toothpaste is mint, which is an indispensable ingredient to give toothpaste a cool feeling. Peppermint is divided into menthol (menthol), peppermint oil and other substances, as well as the spices derived from it. In addition, fruit flavors, such as citrus spices, can also be used, but as toothpaste spices are strictly limited.   9. Fluorine Fluoride inorganic salts in toothpaste, including sodium fluoride, potassium monofluorophosphate, stannous fluoride, etc. Fluoride in toothpaste can fight caries, and low doses of fluoride can make the surface of the tooth stronger. In fact, the main role of toothpaste is cleaning, we should not completely rely on fluoride in toothpaste to fight tooth decay, daily eating habits and hygiene habits are more important.   10. Hydrogen peroxide Also known as hydrogen peroxide, H2O2. Hydrogen peroxide added to a small amount of toothpaste also has a bactericidal and bleaching effect on the mouth, but it is difficult to remove the tooth discoloration caused by pathology, and will stimulate the gums and oral mucosa - so the use of hydrogen peroxide has its own advantages and disadvantages.   11. Western medicine ingredients Antibacterial and anti-inflammatory ingredients will effectively clean the mouth, and can relieve and treat periodontal diseases to a certain extent. But long-term use, easy to cause oral bacteria resistance. Therefore, when using medicated toothpaste, don't forget to refer to the oral doctor's medical advice.

As an emerging category, medical oral care toothpaste in retail pharmacies has shown a certain growth trend, mainly reflected in the following aspects: increasing consumer demand 6: Increasing oral health awareness: Nowadays, people are paying more and more attention to oral health, and the effect of toothpaste is no longer limited to cleaning teeth, but hopes to solve more oral problems, such as periodontitis, gingivitis, bleeding gums, and sensitive teeth. Because of its targeted effect, medical oral care toothpaste can meet these needs of consumers, so it is favored by more and more consumers. Expanding needs of special groups: Some special groups, such as orthodontic people, dental implant people, the elderly, etc., their oral conditions are relatively special, and they need more professional oral care products. Medical oral care toothpaste can provide better oral care for these people, so the market demand is also increasing. Strong efficacy: Compared with ordinary toothpaste, medical oral care toothpaste usually contains a higher concentration of active ingredients, such as antibacterial agents, desensitizers, restorers, etc., which can prevent and treat oral diseases more effectively. For example, toothpastes containing desensitizing ingredients can relieve the symptoms of tooth sensitivity, and toothpastes containing antibacterial ingredients can inhibit the growth of oral bacteria and prevent oral infections. High safety: Medical oral care toothpaste needs to follow strict standards and specifications in the production process, and its quality and safety are more guaranteed. At the same time, the ingredients of this kind of toothpaste have been scientifically verified and tested, and the side effects on the human body are small. Sales channel expansion: Advantages of retail pharmacies: As a professional drug sales channel, retail pharmacies have high credibility and professionalism. When consumers buy medical oral care toothpaste, they are more inclined to choose to buy in retail pharmacies, because they think that the quality of the products in pharmacies is more guaranteed, and pharmacists in pharmacies can also provide professional consultation and advice. Growth in online sales: With the development of e-commerce, more and more consumers choose to buy medical oral care toothpaste online. Online sales channels are not only convenient and fast, but also can provide more product choices and preferential activities, attracting a large number of consumers. Brand and product diversification: Brand competition intensifies: more and more toothpaste brands begin to get involved in the field of medical oral care and launch their own medical oral care toothpaste products. The competition between brands prompts enterprises to continuously improve product quality and service level, and promotes the development of the entire industry. Continuous product innovation: In order to meet the different needs of consumers, the product types of medical oral care toothpaste are also constantly enriched and innovative. In addition to the common desensitizing toothpaste and antibacterial toothpaste, there are also segmented products for different oral problems, such as gum repair toothpaste and oral ulcer toothpaste.

How to choose an economical and practical toothpaste? Experts suggest to pay attention to whether the packaging contains fluoride toothpaste with a fluoride content of more than 0.1% is the best fluoride toothpaste can inhibit plaque, prevent dental caries and help control periodontal disease And different groups of people are suitable for different toothpastes children are best to use special children's toothpaste Pregnant women can choose salt toothpaste love backsliding people can use desensitization toothpaste patients with periodontal disease can consider Chinese herbal toothpaste What are some good ways you can protect your teeth?

"Remove stains from white teeth", "anti-sugar anti-moth", "gingival anti-sensitivity"... Now more and more functional toothpaste, we should pay attention to their own needs when choosing, some toothpaste has health risks, and even cancer risk. 01 These two toothpastes may have health risks   01 Toothpaste containing titanium dioxide Titanium dioxide is often added to toothpaste and adheres to the surface of teeth to make them look white for a short time. Titanium dioxide, as early as 2017, was classified as a class 2B carcinogen. A Class 2B carcinogen is a "probable human carcinogen," meaning that it has been shown to be carcinogenic in animal studies, but the evidence in human studies is not sufficient to determine its carcinogenic risk to humans. This does not mean that the use of toothpaste containing titanium dioxide will definitely cause cancer, because the content of titanium dioxide in toothpaste tested by national formal institutions is very low, and the particle diameter is also within the safe range. However, experts at the French National Institute of Agricultural Research have said that long-term use of things containing titanium dioxide, titanium dioxide nanomaterials may affect health! 02 Toothpaste containing triclosan Triclosan is a broad-spectrum antimicrobial agent that is a common antibacterial and mothproofing substance in toothpaste. Some studies have suggested that triclosan may be a potential cancer risk. In some experimental animals, exposure to low doses of triclosan altered the intestinal flora of mice, adversely affecting colon inflammation and associated colon tumorigenesis; Triclosan also has a certain probability of reacting with chlorinated tap water to produce chloroform, which is mildly teratogenic and can induce liver cancer in mice, and may also have a potential risk for human disease. However, there is still controversy about whether triclosan is carcinogenic, and toothpaste containing this ingredient is still on the market. Trichloride can also interfere with endocrine, especially the effect on female sex hormones is relatively significant. Therefore, pregnant, pregnant, breastfeeding women and children, it is not recommended to use toothpaste containing triclosan for a long time! 02 How to choose toothpaste correctly? Look at these points   It is not necessary to choose too expensive toothpaste, mainly depending on whether it contains fluorine and the composition of friction agent.   Fluoride toothpaste can reduce the probability of dental caries, but be careful not to swallow it when using. Toothpaste mainly uses friction to clean tooth enamel. The main components of friction are calcium carbonate, calcium hydrogen phosphate and silica hydrate. Although calcium carbonate is strong in cleaning, it can damage the enamel on the tooth surface. The latter two ingredients are milder and less likely to damage teeth. In addition, pay attention to the following points: 01 Do not buy toothpaste with too thick friction Coarse particles of toothpaste rub can more efficiently remove pigment from the tooth surface. Although the teeth appear white for a short time, prolonged use can damage the enamel. 02 Don't buy toothpaste that contains alcohol Although alcohol can disinfect and temporarily cover up breath, long-term use will disturb the oral microecological balance and cause oral diseases. 03 Use different toothpastes Using the same toothpaste for a long time may cause resistance to harmful bacteria in the mouth. Switching between different toothpastes is good for maintaining oral health. 04 Do not blindly choose functional toothpaste People with healthy oral cavity can choose ordinary toothpaste, but blind selection of functional toothpaste may bring unnecessary side effects to oral health.

On the plane, you can bring toothpaste, but no more than 100 grams, toothpaste is a paste. According to international aviation law, passengers are not allowed to carry more than 100 grams of paste or 100 milliliters of liquid items on board. If you want to carry toothpaste, be sure to keep the size of the toothpaste under 100 grams. It can be placed in a clear resealable plastic bag (the size does not exceed 20 cm long and 20 cm wide) and carried with you. The total amount of plastic bags does not exceed 1000 ml, and the things inside will not be crowded, so the bag mouth can be resealed, and the large number can only be checked.     Toothpaste is not a contraband, but an item we use frequently in our lives, so we can bring it on the plane. However, it must comply with the relevant regulations and systems for carrying liquids before it can be normally carried on the aircraft, and the carrying amount cannot exceed the regulations, otherwise it cannot be brought into the aircraft.     If the packaging size of the toothpaste is not more than 100 ml, you can take the plane, but if the packaging size is more than 100 ml, even if you use some toothpaste, the amount inside is not more than 100 ml, not allowed to take the plane, you need to check. If the size exceeds 100ml, it cannot be carried, but it needs to be checked. As long as the total amount does not exceed 1000ml, it can be shipped. If you need to carry, be sure to see if the specification on the package exceeds 100ml.     For domestic flights, adult or child tickets 40 kg for first class passengers, 30 kg for business class passengers and 20 kg for economy class passengers. There is no free baggage allowance for passengers with infant tickets. In addition, according to the regulations on carry-on items, each passenger is limited to 5 kg of carry-on luggage. Passengers with first class tickets carry two items per person; Passengers holding business class or economy class tickets are allowed to carry only one item, each of which must be no larger than 20 by 40 by 55 centimeters.

Toothpaste usually doesn't work when it's out of date. Many chemicals contained in toothpaste, such as blowing agents, friction agents, anti-corrosion and antibacterial drugs, will occur after the expiration of chemical reactions, not only cause toothpaste deterioration, but also reduce the toothpaste decontamination and cleaning effect. In addition, the chemical properties of fluoride in toothpaste are relatively active and easy to lose. If the toothpaste expires, it will lose the effectiveness of the toothpaste intended to whiten and prevent cavities. It doesn't hurt, but it doesn't matter if it doesn't work.   Using expired toothpaste may damage the teeth and oral mucosa, suffer adverse effects, and even have allergic reactions. If children accidentally eat expired toothpaste, it can also cause damage to the digestive tract. Therefore, if the toothpaste expires, it is recommended not to continue to use, but should be replaced with a new toothpaste.   However, although the expired toothpaste cannot be used to brush teeth, it can be used to clean furniture, appliances and shoes, etc., to achieve a bright as new effect.

The toothpaste can still be used after three years, but its cleaning effect and taste may be affected. First, the shelf life of toothpaste Toothpaste is a commodity that expires easily, and its shelf life is usually about two years. During the use of toothpaste, the ingredients of toothpaste will be affected by external factors such as air, moisture, and temperature, and gradually lose its cleaning effect and taste. 2. Influencing factors of toothpaste storage The environment in which toothpaste is stored is also an important factor affecting its quality. Light, high temperature, humidity and other conditions will accelerate the deterioration of toothpaste. Therefore, when storing toothpaste, it should be placed in a cool and dry place as far as possible to avoid direct sunlight and wet environments.

The color bar at the bottom of the toothpaste represents the label made by the company to distinguish the use of the toothpaste. The end of the tube of many brands of toothpaste comes in four colors. Red is basically children's toothpaste, not like the Internet said that red is natural + chemical ingredients; Blue is mainly with whitening effect, mainly added whitening additives; Black is not whitening, remove tooth stains; Green is mainly medicinal.   Therefore, the color bar at the bottom of the toothpaste is only a corporate behavior, and the company itself uses a color to distinguish between its different products, which is a color distinction according to the quality and use of the toothpaste, not as a mandatory requirement of the state, and there are no regulations in the industry.       Toothpaste purchase precautions   In the purchase of toothpaste, mainly look at the quality of friction agent. Containing aluminum hydroxide and calcium hydrogen phosphate is better, silica is second, and calcium carbonate is the lowest grade. In addition, the particles of various friction agents are divided into sizes, and the toothpaste with finer particles has less damage to the tooth surface.   Saliva secreted by the human mouth has the function of sterilization. During the day, the amount of saliva secretion is 3-4 times that of the night, which is easy to inhibit the production of bacteria, and eat more during the day, and food residues are easy to remain in the mouth, so you should choose toothpaste with good cleaning function. At night, when people are sleeping, salivary glands secretion is insufficient, should be used to bacteriostatic bactericidal toothpaste to prevent caries.
