How Fluoride Works

Fluoride in drinking water is taken in by teeth still developing below the gum to help create a strong surface, protecting the teeth from cavities.

In children and adults teeth are bathed in fluoride when drinking water, giving teeth the fluoride they need all day long.

Acid produced by bacteria in the mouth can create holes in the surface of the teeth. Fluoride helps protect and rebuild this surface, preventing about 25% of cavities.
