The Brian Lehrer Show The Facts (and Myths) of Water Fluoridation
May 13, 2025
In this engaging discussion, Jessica Steier, an expert in public health, and Linda Birnbaum, a leading scientist emeritus, tackle the contentious topic of water fluoridation. They explore its historical significance in dental health and recent claims of cognitive risks for children. Delving into the National Toxicology Program's findings, they highlight the need for further research. The duo engages in a lively debate on the implications for public health policies, especially regarding access for disadvantaged communities. Tune in for insights that challenge common perceptions!

Episode notes
Fluoride's Public Health Impact
- Fluoride has been added to water supplies in the U.S. since 1945 to reduce dental cavities and improve oral health.
- It is considered one of the greatest public health achievements of the 20th century by the CDC.
Fluoride Exposure and IQ Link
- High fluoride exposure (above twice the recommended levels) is linked to lower IQs in children.
- Emerging evidence suggests potential neurological effects at current fluoridation levels, though more research is needed.
Current Fluoride Levels and IQ Safety
- Most studies linking fluoride to IQ reduction involve levels over double U.S. community water fluoridation.
- Current fluoride levels have not shown compelling evidence of clinically relevant IQ impact according to CDC and pediatric organizations.
