How Does Fluoridation Work?

Fluoride exists naturally in virtually all water supplies

Did you know that fluoride exists naturally in virtually all water supplies? Fluoride reduces decay by strengthening tooth enamel. Water is “fluoridated” when a public water system adjusts the fluoride to a level known to prevent tooth decay. It doesn’t just benefit children. Adding fluoride to water helps adults, too. Drinking fluoridated water throughout the day bathes our teeth in low levels of fluoride to help them stay strong. It is a safe, effective, and affordable way to prevent tooth decay.
