Having beautiful teeth and a confident smile is the best dress for a person. In order to protect the teeth of my children, I will brush and floss them carefully every night.

UK and the United States recommend using fluoride toothpaste (non-low fluorine); Australia recommends using children's low fluorine toothpaste from 18 months.

Regarding the problem of children rinsing and accidentally swallowing, I will explain again. Children do not need to rinse their mouths with clean water. If the amount of toothpaste you use for your baby is appropriate, then swallowing is safe.

The official recommendations of the United States, Australia, Hong Kong and the United Kingdom are: encourage children to spit out toothpaste, but they do not need to rinse their mouths with clean water. Because doing so will take away the fluorine applied to the teeth, and we hope that the fluorine can stay on the surface of the child's teeth and continuously protect the teeth.

If the amount of toothpaste is appropriate, the amount of fluoride in the toothpaste intake of children will not exceed the recommended fluorine intake level (0.05 mg/kg/day). For example, a child with a weight of 15 kg brushes his teeth twice a day, using rice-sized toothpaste (about 0.1 grams of toothpaste, containing about 0.1 mg of fluoride). If you accidentally swallow all toothpaste, the fluorine intake is about 0.2 mg, and the weight-converted dose is 0.013 mg/kg. Under the same conditions, children who use pea-sized toothpaste (about 0.25 g toothpaste, about 0.25 mg fluoride) will consume 0.5 mg fluoride, and 's weight will be 0.033 mg/kg.

Based on my experience in brushing children's teeth, before the age of 3, I will not have too much foam when I use rice grain-sized children's toothpaste, and it will be fine whether I vomit or not. After the age of 3, if you use toothpaste as big as a pea, there will be more foam. At this time, the child will also vomit. Encourage the child to spit out the foam in his mouth, or rinse his mouth with a small amount of water.

👆So much foam is obviously an excessive amount of toothpaste

Desensitizer:

Toothpaste helps reduce tooth sensitivity active ingredients and can reduce oral discomfort caused by sensitivity.

Potassium nitrate and stannous fluoride are the two most common desensitizers in toothpaste. The mechanism of action of the two components is different: the potassium ions in potassium nitrate are depolarized by nerve cells to help teeth reduce sensitivity; the

Another less common anti-sensitivity ingredient is strontium chloride , which also works by blocking the tubules, but there is currently a lack of conclusive evidence to show its principle and mechanism.

Antimicrobial agent:

Stannous fluoride helps relieve gingivitis. pyrophosphate and zinc citrate help reduce the accumulation of tartars (tartar).

In addition, although triclosan and sodium fluoride have been confirmed to work together to prevent tooth caries, plaque and gingivitis, has been no longer available for sale in the United States since early 2019.

The debate about triclosan is largely derived from the experiment of a teacher at Virginia Tech University in the United States. According to research by Dr. Peter Vikesland, products containing triclosan can form chloroform once they react with chlorine-containing tap water. It is colorless and volatile and has been used as an anesthetic, but animal experiments have found that this substance can cause damage to the heart and liver, is mildly teratogenic, and can induce liver cancer in mice, but there is no research data on carcinogenicity in humans. To be on the safe side, both the International Cancer Research Center and the United States have listed chloroform as a suspicious carcinogen that is a potential threat to the human body.

In April 2010, the U.S. Food and Drug Administration announced the launch of an assessment of triclosan's safety. Researchers found that this bactericidal ingredient may interfere with thyroid hormone function and may even make some bacteria resistant to antibiotics. But in terms of "sterilization" in his job, it may not be much better than soap and water.

According to the provisions of the EU and my country's national toothpaste standards, triclosan is a preservative that is allowed to be added to toothpaste, but it is clearly not allowed to exceed 0.3%.

The main function of triclosan is antibacterial, but it is not necessary to add it. For such a controversial ingredient, I suggest to avoid it, avoid it, and then avoid it. If you have used

, don’t worry too much. Please comfort yourself to study the evidence.

Below are the inactive ingredients that are often contained in toothpaste, including friction agents, foaming agents, flavours, moisturizers, thickener or binders, as well as peroxides, etc.

Friction agent:

Modified silica abrasive or enzyme helps clean teeth and helps whiten teeth by physical action.

Common toothpaste abrasives include calcium carbonate , dehydrated silica gel, hydrated alumina (aluminum hydroxide), magnesium carbonate, phosphate and silicate.

Enol is the hardest substance in the human body, but due to the wear of enamel or the recession of gums, the dentin in its deep may gradually be exposed and worn. To this end, scientists have spent decades studying and detecting the effects of dental cleaners on tooth structure.

In the internationally recognized ISO11609-2017 standard, the friction value (RDA) of friction agent generally shall not exceed 250, and it is safe to be less than 250. and the friction value (RDA) of calcium carbonate toothpaste is 253.84. In , it is not recommended to use calcium carbonate as the main friction component, especially children's toothpaste.

Foaming agent:

Foaming agent that produces foam helps dissolve plaque and scale accumulation when brushing teeth. Common foaming agents in toothpaste include sodium lauryl sulfate and N-lauryl sarcosine.

Flavoring agent:

flavoring agent and saccharin-free sweeteners can improve the taste of toothpaste. toothpaste does not contain sugar or any caries-causing ingredients.

Moisturizer:

Moisturizers such as glycerin, propylene glycol and sorbitol help prevent toothpaste moisture loss.

Thickener or binder:

Thickener or binder, which can stabilize toothpaste formula, including mineral colloids, natural glues, algal colloids or synthetic cellulose.

Peroxide:

Hydrogen peroxide and urea peroxide help reduce internal stains in teeth.

Allergens and irritants

Toothpaste can cause oral irritation or allergic reactions in rare cases. Essential oils, including spearmint, mint, and cinnamon, are common allergies for oral contact dermatitis, stomatitis, or cheilitis.

It should be noted that these ingredients may not be explicitly mentioned on the packaging, but are uniformly listed as "flavor" . In addition, essential oils, flavor mixtures and menthol may also stimulate the oral mucosa and cause allergic reactions.

Other common ingredients in toothpaste that are allergens or contacting irritants include

citric acid (zinc citrate or potassium citrate in the ingredients list), triclosan, sodium lauryl sulfate, propylene glycol, PEG-8, PEG-12, PEG-1450, cocamidopropyl betaine, paraben and pyrophosphate.

Toothpaste Allergen-induced symptoms of contact dermatitis include erythema, edema, squashing and ulcers in the oral mucosa, gums and tongue, which are often difficult to distinguish from other oral problems.

This time we bought 17 , which has good sales and good reputation. It is well-known to the public, and is all toothpaste containing fluorine. Take them as an example to see how to choose the right toothpaste for your child.

This time the toothpaste "evaluation" has no final victory or defeat evaluation, because I think none of these toothpastes are absolutely good or bad. Instead, you can choose according to the specific situation of the child.

When choosing toothpaste for children, we can consider it from these dimensions:

There are 9 toothpastes in this review, which are designed with flip covers, but black toothpaste and Kao do not have aluminum foil paper, so the cover is leaked.

In terms of toothpaste content, I personally prefer to choose small , because the amount of toothpaste for children is very small, and even if it is very small, it can be used for a long time. In the end, it will feel a little dirty.

and 7 toothpastes are designed to open the lid directly, among which pororo bobole also leaked because the opening is too big.

In the end, there is only left in the Frog Prince is the only press-type design inside.

These toothpastes do not contain triclosan, but they all contain some ingredients that may be sensitized and irritating. This is why we feel a little slight irritation when using toothpaste. Children's toothpaste will be much better for adult toothpaste in this regard, so even if you choose perfluoro toothpaste, children will be much better for children's toothpaste.
