SALT LAKE CITY (AP) — Utah has become the first state to ban fluoride in public drinking water, despite widespread opposition from dentists and national health organizations.
Republican Gov. Spencer Cox signed legislation late Thursday that bars cities and communities from deciding whether to add the mineral to their water systems.
Fluoride strengthens teeth and reduces cavities by replacing minerals lost during normal wear and tear, according to the U.S. Centers for Disease Control and Prevention.
Utah lawmakers who pushed for a ban said putting fluoride in water was too expensive. Cox, who grew up and raised his own children in a community without fluoridated water, compared it recently to being “medicated” by the government.
The ban comes weeks after U.S. Health Secretary Robert F. Kennedy Jr., who has expressed skepticism about water fluoridation, was sworn into office.
More than 200 million people in the U.S., or almost two-thirds of the population, receive fluoridated water through community water. The addition of low levels of fluoride to drinking water has long been considered one of the greatest public health achievements of the last century.
But some cities across the country have gotten rid of fluoride from their water, and other municipalities are considering doing the same. A few months ago, a federal judge ordered the U.S. Environmental Protection Agency to regulate fluoride in drinking water because high levels could pose a risk to the intellectual development of children.

The president of the American Dental Association, Brett Kessler, has said the amounts of fluoride added to drinking water are below levels considered problematic.
Opponents warn the ban will disproportionately affect low-income residents who may rely on public drinking water having fluoride as their only source of preventative dental care. Low-income families may not be able to afford regular dentist visits or the fluoride tablets some people buy as a supplement in cities without fluoridation.
The sponsor of the Utah legislation, Republican Rep. Stephanie Gricius, acknowledged fluoride has benefits, but said it was an issue of “individual choice” to not have it in the water.
