On May 15, 2025, Florida Republican Gov. Ron DeSantis signed a measure prohibiting local governments from adding fluoride to their water systems, making it the second state in the country after Utah to implement a statewide ban on the mineral.

DeSantis signed the bill at a public event in Dade City, Florida, over the concerns of dentists and public health advocates.

State lawmakers approved the bill last month, requiring the mineral and some other additives be removed from water sources across the state. Utah was the first state to ban fluoride in late March, and its prohibition went into effect last week, while Florida’s provision is effective July 1.

Some local governments in Florida have already voted to remove fluoride from their water, ahead of the statewide ban. Earlier in the 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.
