Utah Considers Banning Fluoride in Public Water Systems

Utah is poised to become the first state to ban fluoride in public water systems. A bill prohibiting the addition of fluoride, a cavity-preventing mineral, has cleared the legislature and awaits Governor Spencer Cox's signature.

The bill's supporters argue that fluoridation is too expensive and should be a matter of individual choice, with options like fluoride pills available. However, opponents, including the Utah Dental Association, warn that eliminating fluoride from public water could have detrimental effects, particularly for low-income residents who rely on it for preventive dental care.

The debate over fluoride's safety and effectiveness has been ongoing for decades. Proponents cite its long history as a public health success, reducing tooth decay by strengthening tooth enamel. Opponents point to potential health risks, including bone fractures, IQ loss, and thyroid disease.

While the science on fluoride's safety remains somewhat contested, its effectiveness in preventing cavities is widely acknowledged. The CDC reports that nearly two-thirds of Americans drink fluoridated water, and studies have consistently shown its positive impact on dental health.

In Utah, only 66 out of 484 water systems currently fluoridate their water. The largest of these is Salt Lake City. In 2023, voters in Brigham City rejected a measure to remove fluoride from their water supply.

Governor Cox's decision on the bill will have significant implications for Utah's public health. If he signs it, Utah will become the first state to ban fluoride, potentially setting a precedent for other states to follow. However, if he vetoes the bill, Utah will continue to fluoridate its water, ensuring access to this important preventive dental measure for its residents.
