Utah’s Fluoride Ban: What It Means for Your Child’s Dental Health
In March 2025, Utah became the first state in the U.S. to ban the addition of fluoride to public drinking water, following the passage of House Bill 81, signed into law by Governor Spencer Cox. This legislation prohibits municipalities from adding fluoride to their water systems, emphasizing individual choice over community-wide dental health measures.
While the bill allows pharmacists to prescribe fluoride supplements, dental health professionals express concern that this approach may not effectively replace the widespread benefits previously provided by community water fluoridation. Dr. Jed Nordfelt, a pediatric dentist in Holladay, Utah, warns that removing fluoride from public water is likely to increase the incidence of dental decay among children.
Understanding Fluoride and Its Role in Dental Health
Fluoride is a naturally occurring mineral known for its ability to strengthen tooth enamel and prevent cavities. Since the 1940s, many U.S. communities have added fluoride to public water supplies, a practice endorsed by the Centers for Disease Control and Prevention (CDC) as one of the top public health achievements of the 20th century.
Pros of Fluoridated Water for Children and Teens
Cavity Prevention: Fluoridated water can reduce tooth decay by approximately 25% across all age groups.
Equitable Health Benefits: It provides consistent dental health benefits, especially for children in low-income families who may have limited access to dental care .
Cost-Effective: Every dollar invested in fluoridation saves about $20 in dental treatment costs.
Cons and Considerations
Dental Fluorosis: Excessive fluoride exposure in young children can lead to dental fluorosis, causing white or brown spots on teeth. While usually mild, it's essential to monitor fluoride intake from all sources.
Overexposure Risks: High levels of fluoride exposure have been associated with potential health risks, such as lower IQ in children, but these findings are linked to fluoride levels above the recommended 0.7 mg/L in U.S. water systems.
Implications of Utah's Fluoride Ban
The legislation, effective May 7, 2025, prohibits cities and communities in Utah from adding fluoride to their water systems. Proponents argue it's a matter of personal choice and cost savings. However, health organizations, including the American Dental Association, warn that the ban could lead to increased dental issues, particularly among low-income populations who rely on fluoridated water for dental health.
Our Recommendations
Use Fluoride Toothpaste: For children under 3, use a rice-sized amount; for those aged 3–6, a pea-sized amount.
Supervise Brushing: Ensure children do not swallow toothpaste.
Consult Your Provider: If you use non-fluoridated or well water, discuss fluoride supplements with your child's healthcare provider.
Regular Dental Checkups: Maintain routine dental visits and consider fluoride varnishes if recommended.
Conclusion
While Utah's decision reflects a shift towards individual choice, it's crucial to consider the broader public health implications. Fluoridated water has been a cornerstone in preventing dental decay, especially in children. As this policy change unfolds, staying informed and proactive in your child's dental care is more important than ever.
