The CDC says fluoridation is among the 10 greatest public health achievements of the 20th century. Utah recently became the first state to ban it.

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.

State lawmakers voted for the bill that would prohibit local governments from adding fluoride to water. Supporters argue that the government should not decide whether fluoride is added to water. While opponents of the measure say it helps prevent cavities.
