A new study reveals alarming links between fluoride exposure during pregnancy and childhood neurobehavioral problems, raising concerns about the safety of fluoridated water.
At a Glance
- Higher prenatal fluoride exposure linked to increased neurobehavioral issues in children
- Study finds 0.68 mg/L increase in fluoride exposure nearly doubles risk of neurobehavioral problems
- Research shows association between higher fluoride exposure and lower IQs in children
- Findings challenge current fluoride recommendations for pregnant women and children
- Experts call for reevaluation of fluoride use in public water systems and dental treatments
Groundbreaking U.S. Study Reveals Fluoride’s Impact on Child Development
Researchers from the Keck School of Medicine of USC have conducted the first U.S.-based study examining the effects of prenatal fluoride exposure on childhood social, emotional, and behavioral functioning. The results are concerning for expectant mothers and young children.
The study found that a 0.68 mg/L increase in fluoride exposure was linked to nearly double the chance of neurobehavioral problems in children. This revelation has sparked debate about the safety of fluoride in public water systems and dental treatments.
“Women with higher fluoride exposure levels in their bodies during pregnancy tended to rate their 3-year-old children higher on overall neurobehavioral problems and internalizing symptoms, including emotional reactivity, anxiety and somatic complaints,” said Tracy Bastain, PhD, a senior author of the study.
Once again, @RobertKennedyJr is proven right. A new study from JAMA Pediatrics shows high fluoride exposure can damage developing brains and lower the IQs of our children. @ChildrensHD @calleymeans@nytimes #MAHA #ConfirmRFK pic.twitter.com/49rThDQeTZ

Fluoride’s Impact on Child IQ: A Growing Concern
A separate study published in JAMA Pediatrics has found a statistically significant association between higher fluoride exposure and lower IQs in children. The research revealed that for every 1mg/L increase in urinary fluoride, there was a 1.63-point decrease in IQ.
These findings align with six previous meta-analyses showing similar inverse associations between fluoride exposure and children’s IQs, raising serious questions about the long-term effects of fluoride on cognitive development.
National Toxicology Program’s Fluoride Review
The National Toxicology Program (NTP) conducted a comprehensive systematic review, evaluating the association between fluoride exposure and neurodevelopment. Their findings support the growing concern about fluoride’s impact on child development.
“The NTP monograph concluded, with moderate confidence, that higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children,” read the study’s findings.
The NTP’s meta-analysis, which included 74 studies on children’s IQ and fluoride exposure, found a statistically significant association between higher fluoride exposure and lower IQ scores in children. This comprehensive review adds weight to the growing body of evidence suggesting potential risks associated with fluoride exposure.
Recommendations and Future Directions
Currently, there are no official government recommendations for limiting fluoride consumption during pregnancy. However, in light of these findings, pregnant women and parents are advised to monitor fluoride intake and consider using low-fluoride bottled water and limiting fluoride dental products for children.
As the debate over fluoride safety continues, it’s clear that more research is needed to determine safe exposure levels and inform public health policies. The findings from these studies underscore the importance of reevaluating current practices and guidelines surrounding fluoride use in public water systems and dental treatments.
As we await further research and updated guidelines, it’s crucial for parents and expectant mothers to stay informed about the potential risks associated with fluoride exposure and make educated decisions about their families’ health.
