Florida is poised to ban fluoride in public water supplies, following the passage of a bill in the state legislature. The move positions Florida to become the second state in the nation to prohibit the use of fluoride in municipal water systems, a decision that has sparked debate among lawmakers, health professionals, and residents.

Florida Fluoride Ban Advances in Legislature

The Florida Legislature House of Representatives voted 88 to 27 in favor of a bill that would effectively ban fluoride from public water systems. The legislation, known as SB 700 or the Florida Farm Bill, does not specifically mention fluoride by name. Instead, it restricts the use of certain additives in water systems, which includes the chemical compound fluoride.

The bill now awaits the signature of Governor Ron DeSantis. If signed into law, Florida will join Utah as the only states to enact such a ban on water fluoridation.

Background on Fluoride in Public Water

Fluoride has been added to public water supplies in the United States for decades. The practice began as a public health measure to help reduce tooth decay and improve dental health, particularly in children.

Major organizations, including the American Dental Association, the American Academy of Pediatrics, and the Centers for Disease Control and Prevention (CDC), continue to support water fluoridation. The CDC states that drinking fluoridated water helps keep teeth strong and reduces the risk of cavities.

Arguments For and Against the Fluoride Ban

Supporters of the Ban

Proponents of the Florida fluoride ban argue that removing the mineral from water systems could save local governments money. They also claim that fluoride does not improve overall water quality and that its addition should not be mandated at the state level. In fact, some communities have already taken steps to end fluoridation, such as when Fort Pierce Utilities ended the use of fluoride in drinking water following local debates.

• Supporters say the ban allows for more local control over water additives.
• They believe cost savings could benefit municipalities.
• Some express concerns about potential health effects, despite scientific consensus on safety at recommended levels.

Opponents of the Ban

Opponents, including many public health officials and dental professionals, warn that banning fluoride in public water supplies could negatively impact dental health, especially among lower-income families who may not have regular access to dental care.

• Rep. Daryl Campbell (D-FL) argued that the measure would hurt everyday Floridians who rely on tap water for dental protection.
• Miami-Dade County Mayor Daniella Levine Cava called the decision “deeply disappointing,” stating it disregards the consensus of medical experts.
• Public health groups stress that fluoridation is a safe, affordable, and effective public health tool.

National Context: Other States and the Anti-Fluoridation Movement

If signed into law, Florida will follow Utah, which became the first state to ban fluoride in public water supplies in March 2025. Utah’s law takes effect in May and prohibits any government entity from adding fluoride to water systems.

Other states, including Kentucky, Massachusetts, Nebraska, Wisconsin, and North Carolina, have seen similar legislation introduced. However, none have enacted statewide bans as of April 2025.

Hawaii, which has never mandated water fluoridation, has the highest rate of tooth decay among children in the U.S., according to a 2015 study by the state health department. Only 11% of Hawaii residents are served by a fluoridated community water system.

Expert Opinions on Water Fluoridation

Most dental and medical organizations continue to endorse fluoridation as a safe and effective way to prevent tooth decay. The CDC reports that community water fluoridation reduces cavities by about 25% in children and adults.

Opponents of fluoridation, including some political figures, argue that individuals should have the right to choose whether or not to consume fluoridated water. The anti-fluoridation movement has grown in recent years, with some citing concerns about potential health risks, despite a lack of evidence at recommended levels. For example, St. Lucie County halted water fluoridation amid rising health concerns, reflecting a shift in local sentiment.

Potential Impact on Port St. Lucie and St. Lucie County

If the ban is signed into law, public water systems in Port St. Lucie and across St. Lucie County will be required to stop adding fluoride. Local officials may need to adjust water treatment processes and communicate changes to residents.

Families who rely on community water for dental health may need to seek alternative sources of fluoride, such as toothpaste or supplements, especially for children at higher risk for cavities.
