Robert F. Kennedy Jr. announced on January 20, 2024 that “the Trump White House will advise all U.S. water systems to remove fluoride from public water.” He stated that “fluoride is an industrial waste associated with arthritis, bone fractures, bone cancer, IQ loss, neurodevelopmental disorders, and thyroid disease.”
Trump’s response to NBC News: “Well, I haven’t talked to him about it yet, but it sounds OK to me. You know, it’s possible.”
At campaign events, Trump elaborated on Kennedy’s potential role:
- “I’m going to let him go wild on health. I’m going to let him go wild on the food. I’m going to let him go wild on medicines.”
- “He can do anything he wants. He wants to look at the vaccines. He wants — everything. I think it’s great.”
Scientific Evidence and Health Data
Benefits of Fluoridation
- Reduces cavities by 25% in children and adults (CDC data)
- Schoolchildren in fluoridated communities have 2.25 fewer decayed teeth compared to non-fluoridated areas
- First implemented in Grand Rapids, Michigan in 1945
- Currently serves 209 million Americans (74% of population)
Recent Research Findings
- National Toxicology Program (August 2024):
- Higher fluoride levels (>1.5 mg/L): Linked to lower IQ in children
- Lower levels (0.7 mg/L recommended level): Evidence less consistent
- Federal Court Ruling (September 2024):
- Judge Edward Chen ordered EPA to take additional measures
- Cited possible risks to children’s intellectual development
- Did not specify required actions
- National Toxicology Program (August 2024):
Health Organization Positions
CDC Statement (May 2024): “Water fluoridation has been identified as the most cost-effective method of delivering fluoride to all members of the community regardless of age, educational attainment, or income level.”
American Academy of Pediatrics: “Water fluoridation is an equitable and inexpensive way to ensure that prevention of dental disease reaches everyone in a community.”
American Dental Association: “Throughout more than 70 years of research and practical experience, the overwhelming weight of credible scientific evidence has consistently indicated that fluoridation of community water supplies is safe.”
Known Health Effects
Documented Benefits
- Strengthens tooth enamel
- Prevents mineral loss from teeth
- Reduces cavity formation
- Cost-effective public health measure
Documented Risks
- Dental fluorosis (cosmetic changes to enamel)
- Usually presents as mild white markings
- Severe cases rare in U.S.
- Skeletal fluorosis (rare in U.S.)
- Causes weaker bones and joint pain
- Occurs with very high exposure over many years
- Dental fluorosis (cosmetic changes to enamel)
Current Implementation Status
- Nearly 75% of U.S. population receives fluoridated water
- Some cities opt out (e.g., Portland, Oregon; Tucson, Arizona)
- EPA currently reviewing regulation requirements
- CDC maintains recommended level of 0.7 mg/L

Expert Analysis
“There is no known benefit of fluoride consumption to the developing fetus,” said Dr. Ashley Malin, University of Florida’s College of Public Health. “But we do know that there is possibly a risk to their developing brain. We found that each 0.68 milligram per liter increase in fluoride levels in the pregnant women’s urine was associated with nearly double the odds of children scoring in the clinical or borderline clinical range for neurobehavioral problems at age 3, based on their mother’s reporting.”
The researchers’ analysis of fluoride exposure patterns revealed levels consistent with those typically found in fluoridated communities. However, they noted important methodological limitations regarding the generalizability of their findings to broader U.S. populations. The study identified significant variability in individual fluoride exposure stemming from diverse dietary habits – including consumption patterns of tap versus filtered water, naturally fluoride-rich foods like green and black tea, certain seafoods, and produce exposed to fluoride-containing pesticides. This complex web of exposure sources highlights the need for more comprehensive research to establish nationally representative conclusions about fluoride’s population-level impacts.
Historical Context
- 1945: First U.S. water fluoridation in Grand Rapids, Michigan
- 1950: Federal endorsement of water fluoridation
- 2015: Recommended levels lowered to address fluorosis concerns
- 2024: Ongoing debate about optimal levels and potential risks
Latest Research Developments
The 2024 Cochrane Collaboration Report, a prestigious systematic review of fluoridation research, revealed nuanced findings about water fluoridation’s contemporary impact on dental health. Their analysis quantified the protective effect of fluoridated water on children’s primary dentition, documenting a modest but measurable reduction in cavity formation. The researchers stated, “We found that adding fluoride to water supplies increases the number of people with dental fluorosis. If water contains 0.7 mg/L of fluoride, about 12% of people may have dental fluorosis that causes them to be bothered about how their teeth look, and about 40% of people may have dental fluorosis of any level. We were unsure whether fluoride in water leads to other unwanted effects.”
Statistical analysis demonstrated that water fluoridation contributed to an average reduction of approximately one-quarter of a tooth decay incident per child. While this represents a tangible public health benefit, the effect size appears smaller than historically reported in earlier decades of fluoridation research.
The report’s authors note a significant contextual shift in dental health practices that may explain these findings. The ubiquity of fluoride-containing toothpaste in modern oral hygiene routines potentially diminishes the relative impact of water fluoridation compared to its historical effectiveness. “The evidence suggests that water fluoridation may slightly reduce tooth decay in children,” explained co-author Dr Lucy O’Malley, Senior Lecturer in Health Services Research at the University of Manchester. “Given that the benefit has reduced over time, before introducing a new fluoridation scheme, careful thought needs to be given to costs, acceptability, feasibility and ongoing monitoring,” she added.
This observation raises important questions about the contemporary cost-benefit analysis of municipal water fluoridation programs in an era where multiple fluoride delivery mechanisms exist. However, the researchers emphasize that even modest benefits, when applied across entire populations, may still represent meaningful public health gains, particularly in communities with limited access to dental care.
Public Health Implications
Current reach:
- 209 million Americans receive fluoridated water
- Implementation varies by municipality
- Local governments maintain control over fluoridation decisions
- Cost-effective method for widespread dental health protection
Future considerations:
- Ongoing research into optimal levels
- Balance of benefits vs. potential risks
- Need for continued monitoring and adjustment of recommendations
- Importance of considering alternative fluoride sources (toothpaste, etc.)
Ongoing monitoring systems track both the benefits and potential risks of fluoridation programs. These surveillance efforts provide crucial data for policy refinement and help ensure public health interventions remain both effective and safe. The dynamic interplay between emerging research, public health goals, and implementation challenges continues to shape America’s approach to water fluoridation.
