State lawmakers voted for the bill that would prohibit local governments from adding fluoride to water. Supporters argue that the government should not decide whether fluoride is added to water. While opponents of the measure say it helps prevent cavities.

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.

The CDC says fluoridation is among the 10 greatest public health achievements of the 20th century. Utah recently became the first state to ban it.
