Fluoride Bans Could Cause Cavity Spike,Cost Billions
Updated May 31,2025
Following through on earlier promises,Robert F. Kennedy Jr.’s advocacy against water fluoridation is gaining traction, with some states already banning the practice. A new study examines the potential consequences of eliminating fluoride from the nation’s water supplies,estimating a notable increase in childhood cavities and associated costs.
Utah and Florida have recently prohibited the addition of fluoride to public drinking water, citing concerns about potential risks to children’s brain development. Advocates like Kennedy argue for individual choice regarding fluoride exposure.
The study, published in JAMA Health Forum, projects that a nationwide ban on water fluoridation could led to a 7.5% increase in cavities among children aged 0-19 within five years. This translates to 25.4 million additional affected teeth and an estimated $9.8 billion in extra dental costs.
Mark Moss, a dental epidemiologist at East Carolina University, noted the study’s importance in understanding the potential impact of ceasing fluoridation. He emphasized the well-established benefits of fluoride for dental health.
The artificial addition of fluoride to U.S. water supplies began decades ago after studies showed lower cavity rates in areas with naturally higher fluoride levels.It was hailed as a major public health achievement, though it has faced controversy, including claims dating back to the 1960s.
more recently, concerns have grown regarding fluoride’s potential impact on children’s IQ, fueled in part by Kennedy’s promotion of the idea.
Lisa simon, a study author and researcher at Brigham and Women’s Hospital, emphasized the proven success of fluoride in reducing dental disease. She acknowledged concerns about adding substances to water but highlighted the widespread benefits, especially for those lacking access to dental care.
The study modeled the impact of removing fluoride from water supplies using a national dataset of children, predicting increased cavities based on the loss of fluoride exposure.
Experts suggest the study’s cost estimates may be conservative, failing to account for factors like parents’ time off work, emergency dental visits, and the need for a larger dental workforce.
Moss said the dental care system is already strained, particularly for Medicaid patients and the uninsured, and an increase in cavities could overwhelm it.
The study did not address potential IQ effects, citing research suggesting no impact at typical U.S. exposure levels. However, Bruce Lanphear, a medical epidemiologist at Simon Fraser University, noted that if IQ concerns are validated, the economic implications could be significant.
Lanphear also questioned the study’s reliance on water fluoride levels as a proxy for total exposure,advocating for urine tests to capture other sources.
Even alternatives to fluoridated water are facing scrutiny. The Texas attorney general has launched investigations into fluoridated toothpaste companies, and the FDA is moving to remove fluoride tablets from the market.
Scott Tomar, a dentist and epidemiologist, criticized the FDA’s evidence for removing fluoride tablets as weak.
Experts generally agree that the fluoride debate has become overly politicized, moving away from scientific evidence.
An HHS spokesperson stated that fluoride is unique as a water additive because it doesn’t treat the water itself. The spokesperson also cited a potential link between fluoridation and IQ, referencing a 2024 monograph and 2025 meta-analysis by the National Toxicology Program. HHS is directing the CDC to re-evaluate fluoride recommendations.
Lanphear suggested a reassessment of fluoride’s benefits and risks by the National Academies, but noted that recent budget cuts may hinder such efforts.
“I think this is very crucial, because it really helps us sort out what the course of action would be if communities choose to stop fluoridation, and it informs the calculation of the impact,” said Mark Moss, a dental epidemiologist at East Carolina University.
What’s next
The CDC will reconvene the Community Preventative Services Task Force to study and make new recommendations on fluoride, possibly under Kennedy’s direction.
