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.

If the bill is signed by Gov. Ron DeSantis, Florida would become the second state to ban fluoride, as a backlash against the oral health measure grows.

Florida’s legislature passed a law banning fluoride in drinking water, a move that advances growing skepticism among conservative lawmakers towards long-accepted dental hygiene.
