LOUISVILLE, Ky. (WDRB) -- Kentucky may let local communities decide whether to add fluoride to drinking water, sparking debate over safety.

Rep. Mark Hart, R-Falmouth, and Sen. Greg Elkins, R-Winchester, introduced a new version of House Bill 16.

The bill would remove the state mandate requiring water producers to fluoridate water.

Dr. Jack Kall, a dentist with the International Academy of Oral Medicine and Toxicology, told lawmakers studies suggest fluoride in water may lower children’s IQ.

He said fluoride in toothpaste is enough to prevent tooth decay.

Supporters say the bill is about local control, not promoting or opposing fluoride.

Rep. T.J. Roberts, R-Burlington, called it “a good piece of legislation that expands the ability for community-based decision making” according to news release. 

Rep. Matthew Lehman, D-Newport, noted that countries without water fluoridation often have publicly funded dental programs.

The bill also protects local water districts from civil and criminal liability.

Lawmakers cannot take action until the 2026 legislative session begins Jan. 6.
