Currently 77.0% of Floridians served by community water systems receive optimally fluoridated water.

Adding fluoride to the public water supply is the most cost-effective means of preventing dental decay with positive effects ranging throughout all ages. The constant contact of low concentrations of fluoride on teeth that occurs when people drink fluoridated water has been shown through studies and reviews of studies to significantly reduce dental caries.

State funds and technical assistance are available through the Public Health Dental Program to help Florida communities with initial efforts to authorize fluoridation and start-up costs. Since 1949 when Gainesville became the first community to initiate water fluoridation, the State of Florida trend has increased steadily to include more and more families gaining access and benefitting from the protective properties of optimally fluoridated water. If your community is interested in gaining access to fluoridation please contact the Public Health Dental Program at or 850-245-4333.

April 27, 2015 – Recommendations for Fluoride Concentration in Drinking Water to Prevent Cavities

Through this final recommendation, the U.S. Public Health Service (PHS) updates and replaces its 1962 Drinking Water Standards related to community water fluoridation—the controlled addition of a fluoride compound to a community water supply to achieve a concentration optimal for dental caries prevention. For these community water systems that add fluoride, PHS now recommends an optimal fluoride concentration of 0.7 milligrams/liter (mg/L).

Learn more about the proposed changes on the Centers for Disease Control and Prevention Community Water Fluoridation: Questions and Answers page.
