During a televised official discussion on the 10th of April led by the then President Donald Trump, the Department of Health and Human Services (HHS) Secretary, Robert F. Kennedy, suggested that there’s potential harm associated with fluoride exposure, especially among children. This was based on the scientific evidence suggesting a possible link to a decrease in intelligence quotient or IQ. Working in close collaboration with the Environmental Protection Agency Administrator, Lee Zeldin, Kennedy expressed his commitment towards reassessing the rules surrounding fluoride due to the new findings presented by the National Toxicity Program.
Secretary Kennedy had raised pertinent points about fluoride exposure during his public address in Utah. Remarkably, Utah had recently been recognized as the first state in the United States to prohibit the addition of supplemental fluoride to water supplies. Kennedy was unequivocal in his assertions, ‘Fluoride should not be in our water.’ His position relied on his belief that fluoride quantities in toothpaste and mouthwash were already sufficient.
The argument against the use of fluoride according to Kennedy was compelling. Various tests using both animal and human models had demonstrated that excessive fluoride exposure could trigger significant IQ reductions. Moreover, these losses appeared to be directly proportional to the amounts ingested making it a major concern that touched on public health.
Contrary to some misconceptions, fluoride does not serve to replace the act of brushing one’s teeth. It certainly aids in protecting the enamel layer from acidic substances but doesn’t neutralize the acids themselves. However, fluoride has been associated with cavity prevention and reducing other dental issues.
Recent data from the Centers for Disease Control and Prevention (CDC), dating back to 2020, indicated that a majority (62.9 percent) of American citizens get their water supply containing fluoride. This might be acquired naturally from the water supply or from local water systems where fluoride might be added. The beginnings of this practice trace back to the early 1900s when researchers uncovered a critical link between fluoride levels in water sources and the dental health of the surrounding populations.
While high fluoride concentrations was linked to teeth discoloration, lower amounts were found beneficial for inhibiting tooth decay. An interesting case study is that of Grand Rapids in Michigan. Known for its naturally low fluoride concentration in water, Grand Rapids resorted to artificially adding fluoride to its water system in 1945. This practice was widely adopted across the U.S. shortly thereafter.
Questions have arisen around the validity of Kennedy’s claim as there is no comprehensive research establishing a link between fluoride exposure and IQ loss. Additionally, the fluoride concentration levels found in most U.S. water supplies, actively monitored by both the CDC and Environmental Protection Agency (EPA), fall within safe limits.
Kennedy had based his argument on the National Toxicology Program (NTP) findings from the HHS, published in August 2024. Contrary to his reference as ‘toxicity’, their report stated a ‘moderate confidence’ in a correlation between fluoride concentrations over 1.5 milligrams per liter and a decrease in children’s IQ. However, the CDC’s recommended fluoride concentration is far lower, standing at 0.7 mg/L, which is roughly equivalent to 3 droplets of water in a large 55-gallon barrel. By 2020, only a meager 0.59% of Americans lived in regions with fluoride concentrations exceeding 1.5 mg/L in their water supplies.
The NTP report does not make any direct claims about the effects of fluoride added to drinking water at a concentration of 0.7 mg/L, as found in many countries including the United States and Canada, on IQ. This leaves a significant gap in the argument presented by Kennedy.
While higher fluoride levels can indeed have adverse health effects, these effects are not as drastic as Kennedy suggests. The legal maximum fluoride concentration allowed by EPA in water supplies is 4 mg/L. For any concentrations over 2 mg/L, water suppliers are obliged to inform local consumers and take steps to reduce it if it goes above the legal limit, else face potential legal action from the EPA.
Nevertheless, no direct association has been proven between heightened fluoride intake and negative impacts on neurological development. The primary health concern in association with excessive fluoride consumption is dental fluorosis, a condition resulting in cosmetic tooth discolouration, though this is typically benign.
Furthermore, dental fluorosis is known to cause white or brown spots on the teeth. Statistically, this cosmetic tooth issue is far more commonplace than most people realise. ‘Most people around the globe, and certainly within the United States, have some form of fluorosis due to naturally occurring fluoridated water.’
Despite the discoloration, fluorosis is generally nothing more than a cosmetic issue. On rare occasions, severe fluorosis can lead to pits developing in the teeth. However, this is not a widespread concern in the United States.
Sophisticated tracking and regulatory tools are in place to ensure the fluoride levels in water stay within the safe and legally permissible limit of 4 mg/L. When occasional incidents of high fluoride levels do occur, stringent measures are taken to restore the fluoride concentration to acceptable levels to prevent the outbreak of fluorosis.
Looking at the broader perspective, Secretary Kennedy’s concerns about fluoride and its impact on IQ levels have sparked a discussion around public health measures. While current research doesn’t fully support his claims, these conversations may spur further studies and a deeper examination of our water sources and overall health.
