The Tennessee Republican Party is pushing for a ban on fluoride in drinking water. The bill, SB 0162/HB 2396, was introduced by Rep. Michele Reneau and Sen. Joey Hensley. It would prohibit public water system operators from adding fluoride to their water systems. However, dental experts have argued that this move would be a step backwards for public health. The American Dental Association supports fluoridation, calling it an effective public health measure.
