Removing fluoride from public drinking water may lead to millions more cavities in US children, study estimates
- A new study published in 2025 estimates that removing fluoride from US public drinking water would cause 25.4 million additional decayed teeth in children within five years.
- This concern arises as some states like Utah and Florida have banned fluoridation amid debates on potential IQ risks linked to excessive fluoride exposure.
- The modeling study found that removing fluoride would add $9.8 billion in dental treatment costs and increase cavities disproportionately affecting children lacking dental care access.
- Dr. Lisa Simon, co-author of the study, noted that cavities cause pain, missed school, and long-term health effects, while current federal guidance finds no IQ effects at recommended fluoride levels.
- Experts warn that ending fluoridation threatens decades of oral health progress and may overwhelm dental systems, especially impacting vulnerable populations at the highest risk of decay.
