Florida Gov. Ron DeSantis on May 15 signed a bill that made the Sunshine State the second to ban fluoride from its drinking water systems.
He also said that fluoride is “readily available now.”
Some local governments in Florida have already voted to remove fluoride from their water ahead of the statewide ban. Earlier this month, Miami-Dade County commissioners voted to override a veto by Mayor Daniella Levine Cava and move forward with plans to remove fluoride from the county’s drinking water.
Fluoride is a mineral that has been added to drinking water since the 1940s to strengthen teeth and reduce cavities by replacing minerals lost during normal wear and tear, according to the Centers for Disease Control and Prevention.
Excess fluoride intake has been associated with streaking or spots on the teeth, and studies have also found a link between excess fluoride and problems with brain development.
In 2024, a landmark ruling on the matter was issued by a federal judge in California who told the U.S. Environmental Protection Agency (EPA) to review the risks of adding fluoride to drinking water.
The agency was mandated by U.S. District Judge Edward Chen to make sure that there is a margin between the hazard level and the exposure level.
“If there is an insufficient margin, then the chemical poses a risk,” the judge said in the September 2024 order. “Simply put, the risk to health at exposure levels in United States drinking water is sufficiently high to trigger regulatory response by the EPA [under federal law].”
When Utah Gov. Spencer Cox signed the state’s fluoride bill into law, multiple medical associations said they opposed the move.
The ADA added that Utah’s measure, which went into effect earlier this month, would “take away the most effective, efficient and equitable way for dental disease prevention.”
