What are the benefits of fluoride?

When used in appropriate amounts it encourages “remineralization,” a strengthening of weak areas on the teeth such as the pits and the fissures on the teeth. Fluoride occurs naturally in water and in many different foods, as well as in dental products such as toothpaste, mouth rinses, gels, varnish and supplements. Fluoride is effective when combined with a healthy diet and good oral hygiene.
