Utah is on the verge of becoming the first state in the United States to ban fluoride from public water systems. House Bill 81 (HB81), introduced by Republican lawmakers Rep. Stephanie Gricius and Sen. Kirk A. Cullimore, has passed both chambers of Utah’s legislature and is now awaiting Governor Spencer Cox’s signature. If signed into law, this legislation would prohibit any individual or political subdivision from adding fluoride to water intended for public water systems. The bill also repeals previous laws that allowed fluoridated water upon resident request or under emergency circumstances.

The proposed law goes further by allowing pharmacists to prescribe fluoride supplements to individuals who may want them, while directing Utah’s Division of Professional Licensing to establish guidelines for prescribing fluoride. If approved, the law would take effect on May 7, 2025.

Arguments Supporting the Ban

The push for banning fluoride in public water systems stems from growing concerns about its potential health risks and a broader mistrust of government-mandated health policies. Critics of fluoridation often cite studies suggesting possible negative effects associated with high levels of fluoride exposure:

1. Concerns About Cognitive Development: A report published in JAMA Pediatrics found an association between higher prenatal fluoride exposure and lower IQ scores in children. However, it is important to note that many of these studies were conducted outside the United States in countries where natural fluoride levels are significantly higher than those regulated in U.S. drinking water.
2. Federal Report Findings: A recent report by the U.S. Department of Health and Human Services’ National Toxicology Program evaluated studies from countries such as Canada, China, India, Iran, Pakistan, and Mexico. It found that drinking water with more than 1.5 milligrams per liter of fluoride was consistently associated with lower IQs in children exposed at these levels.
3. Mistrust Post-COVID-19 Pandemic: The COVID-19 pandemic has fueled skepticism toward government health mandates among certain groups, leading some individuals and organizations to question long-standing practices like water fluoridation.

Counterarguments Against the Ban

Despite these concerns, major public health organizations strongly support fluoridation as a safe and effective measure for preventing tooth decay:

1. Public Health Benefits: According to the Centers for Disease Control and Prevention (CDC), fluoridated water reduces cavities by approximately 25% in both children and adults by strengthening tooth enamel through its interaction with calcium and phosphate.
2. Endorsements from Medical Associations: The American Dental Association (ADA) and American Academy of Pediatrics (AAP) endorse community water fluoridation as a cost-effective method for improving oral health across populations.
3. Scientific Evidence Supporting Safety: An Australian study published recently found no link between early childhood exposure to fluoridated water at recommended levels and negative cognitive neurodevelopmental outcomes; instead, it observed slightly higher IQs among children who consumed fluoridated water regularly.
4. Regulated Fluoride Levels in U.S. Water Systems: In contrast to countries cited in anti-fluoridation research where natural fluoride levels can exceed 1.5 milligrams per liter, U.S.-regulated public drinking water systems maintain much lower levels—typically around 0.7 milligrams per liter as recommended by federal agencies like the U.S Public Health Service.

Implications if HB81 Becomes Law

If Governor Cox signs HB81 into law:

• Utah will become the first state in the nation to completely ban fluoride from public drinking water.
• Residents seeking fluoride for dental health will need prescriptions for supplements provided through pharmacies.
• This decision could set a precedent for other states considering similar measures amid rising anti-fluoridation sentiment.

However, this move could also lead to increased rates of tooth decay over time if alternative methods for delivering fluoride are not widely adopted or accessible.

Broader Context

The debate over fluoridation reflects a larger trend across parts of the United States where local governments have opted out of adding fluoride to their municipal water supplies due to public opposition or ballot measures initiated by anti-fluoride groups like the Fluoride Action Network (FAN). Since 2010, over 150 towns or counties have voted against fluoridating their public drinking water systems.

While proponents argue that removing fluoride undermines decades of progress made in reducing dental disease through community-wide interventions, opponents claim that individuals should have more control over what substances they consume via public utilities.

Top 3 Authoritative Sources Used

1. Centers for Disease Control and Prevention (CDC)
   The CDC is one of the most authoritative sources on public health issues globally and has extensively studied community water fluoridation’s safety and effectiveness over decades.
2. American Dental Association (ADA)
   The ADA provides evidence-based recommendations regarding oral health practices and supports community-level interventions like fluoridated drinking water as a means to prevent cavities effectively.
3. U.S Department of Health & Human Services’ National Toxicology Program (NTP)
   The NTP conducts rigorous evaluations on environmental substances’ potential toxicity; its recent report on global studies examining high-fluoride exposure informed much of this debate surrounding cognitive effects linked with excessive intake levels abroad versus regulated amounts domestically.
