Toothpaste is swallowed when brushing your teeth. Is it harmful to your health?

Generally speaking, swallowing a small amount of toothpaste by mistake has little effect on health. At present, the main components of mainstream toothpaste in the market are friction agent (such as calcium carbonate and calcium hydrogen phosphate), humectant (such as xylitol and polyethylene glycol), surfactant (such as sodium dodecyl sulfate), thickener (such as carboxymethyl cellulose and antler glue), sweetener (such as glycerol and sodium cyclohexylamine sulfonate), preservative (such as potassium sorbate and sodium benzoate) and active additive (such as chlorophyll and sodium benzoate). Some of these ingredients are toxic or pathogenic, such as fluoride, which plays an important role in cleaning teeth. But for the general healthy population, a small amount of fluoride will not cause serious physical injury or induce diseases.

But if you swallow a lot of toothpaste, it will increase the risk of stomach inflammation and ulcer. Usually you should breathe through your nostrils when brushing your teeth, and try not to breathe through your mouth to prevent toothpaste from being inhaled. The amount of toothpaste should be moderate every time you brush your teeth. Excessive toothpaste is not only not conducive to the full play of toothpaste, resulting in waste, but also increases the probability of accidental swallowing; After brushing your teeth, rinse your mouth as much as possible, and use the rapid and repeated squeezing of facial muscles and sufficient water to fully clean the interior and depths of your mouth.
