Robert F. Kennedy Jr. has ventured into yet another contentious scientific discussion, asserting on Saturday that if Donald Trump were to regain the presidency in the upcoming Tuesday election, his administration would advocate for the elimination of fluoride from the nation’s public water systems.
“On January 20, the Trump White House will advise all U.S. water systems to remove fluoride from public water. Fluoride is an industrial waste associated with arthritis, bone fractures, bone cancer, IQ loss, neurodevelopmental disorders, and thyroid disease,” Kennedy, who was a former independent presidential candidate, declared emphatically in a social media post that attracted considerable attention and debate.
Trump has floated the idea that Kennedy, whose previous career as an environmental lawyer lends him credibility on health issues, could oversee an impactful health portfolio should he return to office.
At a recent campaign rally in New York, Trump expressed his enthusiasm for letting Kennedy “go wild on health,” “go wild on the food,” and “go wild on medicines.” Furthermore, during a rally in Michigan the following Friday, Trump emphasized that Kennedy would “have a big role in health care” and expressed agreement with some of his perspectives.
As the debate over the public health practice of fluoridating America’s water supply intensifies, health experts are carefully weighing the implications and the potential consequences for community health and safety.
Fluoride, a naturally occurring mineral found in water and rocks, as well as in certain foods, has been the subject of scrutiny. The mineral can also be a byproduct of industrial processes, raising questions about its safety and impact on public health, as highlighted by the Centers for Disease Control and Prevention (CDC).
In a significant legal development, a federal judge ordered the US Environmental Protection Agency (EPA) in September to implement stricter regulations on the levels of fluoride permissible in drinking water, citing concerns about its potential impact on cognitive development in children.
US District Judge Edward Chen determined that although the evidence linking typical fluoride levels in water to decreased IQ in children remains inconclusive, the potential risk is substantial enough to warrant further investigation, requiring the EPA to elevate its regulatory measures. The ruling, however, left ambiguous what specific actions the EPA must undertake as the agency continues to review the court’s directives.
Experts largely concur that despite the political discourse surrounding fluoride, there is a pressing need for more comprehensive research to better understand its effects, not only on young children but on the general population.
Dr. Ashley Malin, who serves as an assistant professor in the Department of Epidemiology at the University of Florida’s College of Public Health and Health Professions, emphasized to CNN the importance of prioritizing the protection of vulnerable populations from environmental toxicants, stressing that this topic should remain nonpartisan and informed by current scientific knowledge.
“I think that health effects of fluoride on young children, particularly in the realm of neurodevelopment, have been sufficiently studied such that it has now been identified that a hazard to child IQ is present. However, I would argue that more research is needed to better understand impacts of chronic low-level fluoride exposure on adult health outcomes because that research is scarce,” Malin asserted.
A federal review published in August by the National Toxicology Program at the National Institutes of Health has drawn attention to how higher levels of fluoride exposure are linked to lowered IQ in children, indicating a growing concern among scientists regarding public health policies.
This federal program grounded its conclusions on studies that examined fluoride levels approximately double the recommended limits for drinking water, raising substantial health questions among experts and policymakers alike.
However, the review also revealed that while there is evidence linking higher fluoride exposure and IQ deficits, the relationship between lower fluoride levels (below 1.5 mg/L) and children’s IQ was found to be less definitive, indicating a need for further investigation and data collection on this complex issue.
Previous studies have corroborated claims that higher fluoride exposure during pregnancy is associated with declines in IQ in children, further complicating the public health discussion surrounding fluoride use.
A pivotal 2019 study focusing on Canadian mothers and their children found that for every additional milligram per liter of fluoride detected in a mother’s urine, there was an observed 4.5-point decrease in IQ scores in male children, although the same significant association was not noted in females, indicating potential gender differences in fluoride sensitivity that require further exploration.
What we know about fluoride and health
The US Centers for Disease Control and Prevention (CDC) has continually endorsed community water fluoridation as an efficient, cost-effective strategy aimed at enhancing the oral health of Americans across the board, contributing to a significant public health effort.
Prolonged exposure to fluoride beyond the public health recommendations has been linked to skeletal fluorosis, a rare condition in the US that leads to weakened bones and debilitating joint pain, alongside cosmetic dental fluorosis, characterized by unsightly specks or lines on the outer enamel layer of teeth, highlighting the risks of excessive fluoride consumption.
Recent scientific investigations evaluating the relationship between cancer and fluoride levels have failed to establish a direct correlation, as confirmed by both the CDC and the American Cancer Society, producing reassurance about the safety of fluoride at regulated levels.
Furthermore, the available data does not support claims that fluoride exposure can lead to birth defects in humans, as underscored by CDC evaluations that affirm its safety in maternal and child health.
The mineral acts to combat tooth decay by reinforcing the protective outer layer of enamel, which becomes susceptible to erosion from acids produced by bacteria, plaque, and sugars in the mouth, illustrating fluoride’s crucial role in preventive dental health. The introduction of fluoride into public water systems in the United States began in 1945, setting a precedent for oral health initiatives.
Currently, approximately three-quarters of the US population — around 209 million individuals — receive drinking water from fluoridated systems, demonstrating widespread reliance on this public health measure as per the latest CDC statistics.
The responsibility of controlling water supplies primarily resides with state and local governments, which maintain majority jurisdiction over municipal water systems across the nation. However, several communities, including Portland, Oregon, and Tucson, Arizona, have taken steps to opt-out of the fluoridation process, reflecting local public sentiment and concerns.
The efficacy of adding fluoride to water supplies has come under renewed scrutiny, with recent reports indicating that the benefits may not be as pronounced as previously thought, especially given the widespread availability of fluoride in toothpaste since its introduction in the 1970s, potentially altering consumption habits and health outcomes.
In a noteworthy assessment published last month, the Cochrane Collaboration, an esteemed independent organization dedicated to analyzing scientific research, found only minimal advantages associated with adding fluoride to tap water, with evidence suggesting slightly fewer cavities in children’s baby teeth resulting from such practices.
Additional studies reported that the average difference in dental decay attributed to fluoride in water amounted to merely about a quarter of a tooth, emphasizing the limited impact fluoride may have in the broader context of dental health.
Nonetheless, the American Dental Association holds firm in its position, asserting that fluoride present in community water supplies remains “the single most effective public health measure to prevent tooth decay,” advocating for its continued use as a fundamental health initiative.

“Studies prove water fluoridation continues to be effective in reducing dental decay by at least 25% in children and adults, even in the era of widespread availability of fluoride from other sources, such as fluoride toothpaste,” the ADA emphasizes on its official website.
The CDC maintains its endorsement of the safety and effectiveness of community water fluoridation, emphasizing its critical role in promoting public health nationwide.
“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,” the agency affirmed in a statement released in May, underscoring the program’s accessibility and scope.
If you’re apprehensive about your fluoride intake, there are options available: consider switching to bottled water, invest in water filters specifically designed to remove fluoride, and supervise children to ensure they do not swallow their toothpaste, safeguarding their dental health.

N communities with access to fluoride toothpaste,” the ADA stated, emphasizing the robust body of research supporting fluoride’s role in oral health.
The ongoing debate over fluoride in public water supplies highlights a complex interplay between public health policy, community preferences, and emerging scientific evidence, necessitating a nuanced understanding of both the benefits and potential risks associated with fluoride exposure.
As further research unfolds, it remains critical for public health officials, scientists, and the community to engage in an informed dialogue about fluoride’s role in health to ensure that policy decisions reflect both scientific findings and public concerns.
