SALT LAKE CITY, Utah – In a historic move, Governor Spencer Cox has officially signed H.B. 81, a law that prohibits the addition of fluoride to public water systems across Utah, making it the first state in the nation to implement such a ban.
The newly enacted law mandates that all water systems currently adding fluoride must stop by May 7. It also provides an alternative for residents who still wish to receive fluoride by allowing pharmacists to prescribe fluoride tablets.
Impact on Utah Residents
Fluoridation, which has been used for decades to promote oral health, was previously practiced in two counties and several municipalities in Utah, affecting around 1.6 million residents. The standard fluoridation level—0.7 milligrams per liter—is considered beneficial for preventing tooth decay.
Despite the policy shift, water officials say the change will have minimal impact on utility bills. While some providers anticipate a slight reduction—around 90 cents per month per household—others expect no significant change as they phase out existing supplies and equipment.
Debate and Concerns
The bill saw bipartisan support and opposition, sparking intense debate in the legislature. Nationally, Utah’s decision has drawn attention, as it marks the first statewide ban of its kind in the U.S.
Dentists and public health officials have expressed strong opposition, warning that the removal of fluoride could increase rates of cavities, especially among low-income families who may have limited access to dental care.
Dr. Mark Fullner, a dentist in Utah County, voiced concerns about shifting the responsibility to individuals:
“This will mostly impact children from families who aren’t aware of fluoride’s benefits or cannot afford supplements. It puts the burden on adults to administer proper doses, increasing the risk of mistakes.”
The Utah Dental Association (UDA) also criticized the decision, arguing that it disregards decades of scientific research supporting fluoride’s role in preventing tooth decay. In a statement, the organization expressed disappointment, saying:
“This decision ignores overwhelming evidence that community water fluoridation is a safe, effective, and cost-efficient way to protect public health, particularly for children and vulnerable populations.”
Governor’s Office Declines to Comment
Despite the controversy, Governor Cox’s office has remained silent on the backlash, declining to issue further statements regarding the decision.
With Utah setting a precedent, it remains to be seen whether other states will follow suit or whether health organizations will push back against the ban.
