Is fluoride coating good or bad?

Fluorine is a chemical element. For teeth, it can inhibit the production of harmful bacteria and promote tooth firmness (medically called "mineralization"). In addition, fluoride can also enhance tooth resistance, strengthen teeth, relieve tooth decay, reduce allergies and inhibit harmful bacteria. In short, "fluoride" is simply the existence of a boyfriend for the strength of his teeth.

We sometimes worry that it is poisoned. The toxic dose of fluoride is 5mg/kg. The dose of fluoride applied to the whole mouth at one time is far from the toxic dose, and even fewer people actually swallow it. For younger children, the dose will also be reduced as appropriate. If you choose a professional oral health care institution, don't worry too much.

Extended data:

After fluoride coating, fluoride needs to remain on the teeth for a period of time to ensure that fluoride with sufficient concentration can be retained and cured. Therefore, after fluoride coating, we should pay attention to the following two points:

① Do not drink water or rinse your mouth within two hours;

② Try not to eat for four hours and don't brush your teeth that day.

Although fluoride coating is a very effective method to prevent caries, it does not mean that it is omnipotent, even once and for all. Children's dental caries focus on prevention, so we must pay attention to developing good oral hygiene habits, and never take fluoride coating as a lifeline!
