​What is fluoride?

Fluoride is an abundant - naturally occurring element found in rocks, soil and fresh and ocean water. When fluoride is present in drinking water at optimal levels, it has been shown to promote oral health by preventing tooth decay.


Is water fluoridation safe?

As with other nutrients, fluoride is safe and effective when used and consumed properly. More than 50 years of evidence from 162 million Americans and nearly 60 other countries supports the effectiveness of fluoridated water and its ability to inhibit, reduce or even reverse the onset and development of tooth decay. Through continuous research, drinking optimally fluoridated water has been scientifically proven to be safe (not toxic) and effective.


Why fluoridate drinking water?

  • The amount of natural fluoride in water supplies is generally not enough to provide oral health benefits. Water fluoridation is the addition of small amounts of fluoride to a water supply to achieve the optimal fluoride level that helps prevent tooth decay.
  • Fluoridated water benefits the entire community. Fluoridation is the single most effective public health measure to prevent tooth decay and improve oral health over a lifetime.

The American Dental Association (ADA) has a downloadable Fluoridation Facts that provides further information on fluoride. Please visit our Water Blog which also has an article about fluoridation this month.
