Community Water Fluoridation 

Fluoride is a naturally occurring mineral released from rocks into the soil, water, and air. All water sources such as rivers, lakes, and oceans have varying amounts of fluoride. Fluoride has been shown to decrease the rate of tooth decay or cavities when added to toothpaste or water. The acid that is produced when a person eats makes the tooth weaker and increase the chance of developing cavities. Fluoride helps rebuild and strengthen the weakened tooth’s surface, or enamel, and reverses early signs of tooth decay.

Community water fluoridation is the addition of fluoride to drinking water to increase the natural fluoride level up to the recommended level that prevents tooth decay. By providing constant contact with low concentrations of fluoride, drinking fluoridated water reduces tooth decay by 25% in children and adults. Adding fluoride to the public water supply is one of the most cost-effective method of preventing dental decay with positive effects for everyone of all ages. 

Water fluoridation is safe, effective and healthy. The American Dental Association, American Medical Association, American Academy of Pediatrics, World Health Organization, and many other public health, medical, and dental organizations support and recommend community water fluoridation. The Centers for Disease Control and Prevention (CDC) named community water fluoridation one of 10 great public health achievements of the 20th century because of its contribution to the significant decline in cavities in the United States since the 1960s. In 2018, 73% of U.S. population on community water systems had access to fluoridated water according to the CDC.

In 2018, 77.4% of Floridians served by community water systems received fluoridated water. 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.

The U.S. Public Health Service recommends an optimal fluoride concentration of 0.7 milligrams/liter (mg/L) in drinking water. State funds and technical assistance are available through the Public Health Dental Program (PHDP) to help Florida communities with initial efforts to authorize fluoridation and start-up costs. If your community is interested in gaining access to fluoridation, please contact the PHDP at or 850-245-4333. Also see the year of initiation for Florida's fluoridated community water systems.
