Utah Becomes First U.S. State to Ban Fluoride in Drinking Water

Salt Lake City, Utah – March 28, 2025 – Utah has made history as the first state in the United States to outlaw the use of fluoride in public drinking water, following the signing of a controversial new law by Governor Spencer Cox. The legislation, which went into effect this week, has ignited a firestorm of debate, pitting public health advocates against a coalition of skeptics who question the long-standing practice of water fluoridation.

For decades, fluoride has been added to public water supplies across the country to combat tooth decay, a practice widely endorsed by dental professionals and organizations like the American Dental Association. However, the new Utah law reflects growing concerns among some groups that the chemical may carry hidden risks. Proponents of the ban argue that fluoride exposure could be linked to adverse health effects, including a potential reduction in IQ scores among children.

“We’re taking a stand for individual choice and safety,” said State Representative Mark Henshaw, a key sponsor of the bill. “The science isn’t as settled as people think, and Utahns deserve to know what’s in their water.” Supporters point to studies suggesting possible neurodevelopmental risks, though federal health agencies, including the CDC, maintain that fluoridation at recommended levels remains safe and effective.

On the other side of the divide, dentists and public health experts warn that removing fluoride from water could lead to a sharp rise in cavities and other dental problems, particularly among low-income communities who may lack access to alternative fluoride sources like toothpaste or professional dental care. “This is a step backward for public health,” said Dr. Emily Carter, a Salt Lake City dentist and vocal critic of the ban. “The data is clear: fluoride saves teeth, and without it, we’re going to see the consequences in emergency rooms and dental offices.”

The decision has drawn national attention, with both sides digging in for what could become a broader fight over water fluoridation policies. Environmental groups have praised Utah’s move, framing it as a victory against unnecessary chemical additives, while some conservative lawmakers in other states are reportedly eyeing similar legislation. Meanwhile, opponents are already mobilizing, with plans to challenge the law in court or push for its repeal in the next legislative session. 17GEN4.com
