Before assuming the role of health secretary, Robert F. Kennedy Jr. vowed to take action on water fluoridation, claiming that “fluoride will disappear.” Following this promise, states like Utah and Florida have stopped adding fluoride to water due to concerns over its impact on children’s brain development.
A recent study estimated that if more areas ceased fluoridation, an additional 25.4 million children ages 0-19 could see a 7.5% increase in cavities, costing roughly $9.8 billion in dental care. While experts recognize fluoride’s benefits, the study’s findings may struggle to sway the ongoing politicized debate.
Fluoride has been added to U.S. water supplies for decades, credited for reducing tooth decay. However, skepticism has grown, particularly regarding potential negative effects on children’s IQ, fueled by Kennedy’s advocacy.
The researchers of the study employed national data to model the consequences of discontinuing fluoridation, predicting a rise in cavities. Critics noted the cost estimates might be low, as they didn’t account for increased emergency care needs for children with severe dental issues.
Concerns regarding fluoride levels as a proxy for exposure were raised, suggesting that using urine tests might better capture overall exposure. Some political actions against fluoride-related products, like a Texas investigation into toothpastes, have further intensified the debate.
Overall, experts express frustration that the discussion around fluoride has become politicized, overshadowing scientific evidence. The Department of Health and Human Services has indicated plans to re-evaluate fluoride recommendations, but changes may be hampered by recent budget cuts affecting relevant advisory groups.
