Lawmakers in Florida approved a bill to prohibit certain additives in drinking water, effectively banning fluoride, and the measure now goes to Gov. Ron DeSantis for a signature. If it’s finalized, Florida will become the second state to ban fluoride in municipal drinking water.

Florida is poised to become the second state to ban fluoride in public drinking water, over the concerns of dentists and public health advocates who say the mineral is a safe, effective way to protect people of all ages from developing cavities.

The Florida House passed a bill on Tuesday that would ban fluoride in the public water supply. The legislation prohibiting local jurisdictions from adding the chemical to tap water now goes to Gov. Ron DeSantis’s (R-FL) desk for final approval after lawmakers passed SB 700 in an 88-27 vote.
