Can the current toothpaste really whiten, stop bleeding and resist allergy?

First of all, talk about the most basic and important function of toothpaste-moth prevention. Why can toothpaste be moth-proof? Mainly because toothpaste contains low dose of fluoride, which can prevent tooth surface from dissolving, make teeth stronger and effectively prevent dental caries. Generally speaking, the content of fluoride will be marked on toothpaste. Theoretically, the fluorine content of about 0. 1% has obvious moth-proofing effect.

Fluoride toothpaste is effective in preventing dental caries locally, not by ingesting fluoride. Therefore, as long as you don't eat toothpaste directly, brushing your teeth with fluoride toothpaste will not cause excessive fluoride intake.

Whitening toothpaste mostly removes dirt on the tooth surface by physical friction or chemical adsorption, so as to achieve whitening effect. The ingredients of toothpaste indicate that calcium carbonate, silicon dioxide or hydrated silicon dioxide belong to physical friction, while those indicate polyphosphate (sodium hexametaphosphate, tetrasodium pyrophosphate, etc. ) belongs to chemical adsorption.

In addition, whitening ingredients added to some whitening toothpastes can stay on the surface of teeth for a short time after brushing, setting off the bright white of teeth.

It should be noted that effective whitening toothpaste can only reduce or remove exogenous pigments attached to teeth, such as tea, coffee, soy sauce, smoking, and even other symptoms of diseases. The use of hemostatic toothpaste can indeed relieve bleeding symptoms, but it may also delay the treatment opportunity.
