Kentucky water plants would no longer have to add tooth-protecting fluoride to water, under bill approved by a committee
By Liam Niemeyer
Kentucky water utilities would no longer be required to add or adjust fluoride in tap-water supplies — a state requirement since the mid-20th century aimed at improving dental health — under a bill a legislative committee approved Thursday, Feb. 8.
House Bill 141 is the latest effort by Rep. Mark Hart, R-Falmouth, to remove the state requirement for water utilities serving populations larger than 3,000 to add or adjust fluoride levels in drinking water systems to “protect the dental health of the people served.”
Hart, a legislator since 2017, was the only sponsor of making drinking-water fluoridation optional when he filed the first such bill in 2018. The legislation has gained Republican co-sponsors as it has been filed several times over past legislative sessions.
The House State Government Committee heard the proposal for the first time Thursday and approved it 16-1. The bill now goes to the House floor for consideration.
Republicans who voted for the bill, and advocates for the legislation who joined Hart, characterized the bill as providing “local control” for utilities to choose whether or not to fluoridate their water. Those advocating the bill included representatives of Morehead’s municipal utility, Irvine’s municipal utility and the Grayson County Water District.
Some advocates for the bill questioned the efficacy of adding fluoride to tap water and its potential side effects.
“Honestly, it is forced medication,” said Rep. William Lawrence, R-Maysville, a co-sponsor of HB 141. “Whether you’re for or against fluoride, this bill has nothing to do with that. This is a local control — let the local water districts decide what’s best for their district.”
The Centers for Disease Control and Prevention considers community water fluoridation to be one of the 10 greatest public health achievements of the 20th century. The federal public-health agency also has found no “convincing scientific evidence” linking fluoridation to “any potential adverse health effect or systemic disorder.”
Groups representing dentists, oral-health advocates and the dental insurer Delta Dental strongly opposed the bill, saying it would increae tooth decay, particularly among children. Kentucky already ranks among the highest for the number of adults with no teeth.
“We have reached the point where it’s not about the science, it’s about the emotion,” Stephen Robertson, executive director of the Kentucky Dental Association, told the Lantern after the committee approved the bill. “No matter what your position is, you can find something out there that’s going to validate your position.”
Jack Kall, a Louisville dentist and supporter of the bill, showed lawmakers cited graphs from a 2016 magazine article by the Harvard T.H. Chan School of Public Health that questioned the efficacy and safety of fluoridation. That article was strongly criticized by the American Dental Association, saying it relied on a report that was a “biased misinterpretation,” and the dean of the Harvard School of Dental Medicine at the time called for the article to be rescinded.
Kall, citing the graphs, asserted that countries that don’t fluoridate water have had a similar decline in tooth-decay rates as countries that do. He told the Lantern that fluoride can lower intelligence in children; a federal court case is litigating whether the mineral has an effect on brain development.
“It’s a hot topic and science continues to evolve,” Kall said. “We should constantly be reviewing things.”
Robertson said there are studies regarding fluoride that need to be verified and that improvements in nutrition and personal dental hygiene also could improve dental health in Kentucky. But fluoride in drinking water, he said, is a “program that works.” He asked, “Are we willing to take the risk of removing fluoride and seeing what happens?”
