A bill that would ban fluoride and other harmful chemicals from Florida public water systems is heading to Governor Ron DeSantis’ desk.

The Florida House passed the prohibition on Tuesday. The Senate did so earlier in the month. It’s the Senate bill, SB 700, that both chambers ultimately approved.

Fluoride is a chemical agent used in industrial capacities that communities around the U.S. have for decades added to their public drinking-water systems, allegedly to help protect against tooth decay.

Whether it actually prevents tooth decay may be up for debate.
