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.

“Anything that relates to water quality, removing contaminants, things like that, we’re not touching that,” Tuck [the bill sponsor] said. “It’s anything that has to do with health. So fluoride, vitamins, whatever else it is.”
