Louisiana is one vote away from banning fluoride in public water. Dentists warn it could lead to more cavities, especially in kids.

Florida Surgeon General Dr. Joseph Ladapo became the nation's first top state health official to publicly oppose fluoride in water. Since then, more than a dozen other Florida communities have ended fluoridation. Supporters of the ban say it should be about personal choice, The Post reported.

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.
