Fluoride is a natural mineral that builds strong teeth and prevents cavities. It’s been an essential oral health treatment for decades. Fluoride supports healthy tooth enamel and fights the bacteria that harm teeth and gums. Tooth enamel is the outer protective layer of each tooth. Fluoride is especially helpful if you’re at high risk of developing dental caries, or cavities.
Dentists provide professional fluoride treatments in the form of a highly concentrated rinse, foam, gel, or varnish. The treatment may be applied with a swab, brush, tray, or mouthwash.
These treatments have much more fluoride than what’s in your water or toothpaste. They only take a few minutes to apply. You may be asked to avoid eating or drinking for 30 minutes after the treatment so the fluoride can fully absorb.
