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.

Floridians no longer would have fluoridated water if Republican Governor Ron DeSantis signs a measure into law that would ban adding fluoride to public water supplies.

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.
