Florida is poised 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.

The bill does not explicitly mention fluoride, but includes language restricting the use of certain additives in water supplies. The bill now awaits Governor Ron DeSantis’ signature.
