Utah Enacts Ban on Fluoride in Public Drinking Water
Utah has become the first state in the United States to prohibit the addition of fluoride to all public drinking water systems, endorsing contentious proposals previously advocated by Robert F. Kennedy Jr. Governor Spencer Cox formalized the measure into law on Thursday, with the mandate scheduled to take effect on May 7 across all community water systems within the state.
Historical Context of Water Fluoridation
The practice of adding fluoride to public water supplies in the U.S. commenced in the 1940s. This initiative stemmed from scientific research indicating that individuals with elevated levels of fluoride experienced a reduced incidence of dental cavities.
According to the latest data from the Centers for Disease Control and Prevention (CDC), approximately half of Utah residents served by public water systems currently receive fluoridated water, while the other half do not.
Governor Cox’s Statement on Fluoridation Impact
Governor Cox commented on the perceived lack of significant health outcome disparities between the two groups within Utah. ‘Considering these two populations, one might anticipate markedly different health outcomes. However, observable differences have not been evident,’ he stated on Thursday.
RFK Jr.’s Stance and Florida’s Recommendation
Robert F. Kennedy Jr., a vocal figure on public health matters, has long advocated for the elimination of fluoride from the nation’s water supply. He posits that fluoride contributes to serious health issues, including bone cancer, diminished IQ, and neurodevelopmental disorders such as autism.
In the preceding year, Florida became the first state to recommend the removal of fluoride from water systems, aligning with the assertions made by Kennedy.
Debate and Expert Opinions on Fluoride’s Health Effects
Research regarding the potential health effects of fluoride remains mixed, with numerous experts asserting that the evidence is inconclusive. Many maintain that the proven benefits of fluoride for dental health outweigh any possible risks.

The Role of Fluoride in Dental Health
Fluoride strengthens tooth enamel, enhancing its resistance to erosive substances such as citrus fruits, sugary foods, and carbonated drinks. These elements can erode and weaken teeth, increasing sensitivity.
Consequently, fluoride plays a crucial role in preventing cavities and other dental infections.
Approximately 72 percent of the American population using public water systems receive fluoridated water.
Since the widespread implementation of national water fluoridation, there has been a notable decrease in dental problems among children. Dental professionals widely commend the program for its public health benefits.
Concerns and Criticisms Surrounding Fluoride
However, since its inception, the safety of fluoride has been a subject of ongoing debate and concern among critics.
In a November post on X (formerly Twitter), RFK Jr. stated: ‘Fluoride is an industrial byproduct linked to arthritis, bone fractures, bone cancer, IQ reduction, neurodevelopmental disorders, and thyroid issues.’
Expert Rebuttals to Fluoride Concerns
Dr. Paul Offit, a physician specializing in infectious diseases at Children’s Hospital of Philadelphia, challenged Kennedy’s assertions, terming them as misleading in an interview with NPR.
Dr. Offit clarified, ‘Fluoride has undergone extensive testing. It demonstrably reduces dental cavities and lacks credible evidence of causing the chronic illnesses mentioned in that tweet.’
Prevalence of Fluoride in Dental Products and Programs
Fluoride is a key ingredient in the majority of toothpastes. Furthermore, approximately 13 million children participate in fluoride mouth rinse programs, as reported by the National Institutes of Health (NIH). These programs involve students rinsing their mouths with a sodium fluoride mouthwash during school hours.
US Public Health Service Review and Recommendations
In 2015, the U.S. Department of Health and Human Services Agency reassessed the levels of fluoride added to drinking water and subsequently standardized the national recommendation.
Prior guidelines permitted varying concentrations based on local air temperature; however, the 2015 update established a uniform limit of 0.7 milligrams of fluoride per liter of water.
This re-evaluation was not prompted by health impact concerns. Instead, it aimed to address apprehensions that higher fluoride levels could lead to the development of white patches on teeth, a condition known as dental fluorosis.
International Perspectives on Water Fluoridation
Critics frequently highlight that several countries have eliminated fluoride from their water supplies.
Germany, the Netherlands, and Sweden have discontinued water fluoridation programs, opting for alternative national dental health initiatives.
It is important to note that these nations have not outright banned fluoride. For example, Germany has a history of incorporating fluoride into salt as a public health measure.
Arguments Against Water Fluoridation in Modern Context
Opponents of water fluoridation contend that while it might have been necessary in the early 20th century when access to fluoride dental products was limited, contemporary society offers ample fluoride exposure through toothpaste and other means. They argue that excessive fluoride exposure could be detrimental in the modern era.

Recent Study Linking High Fluoride Exposure to Lower IQ
Most recently in the U.S., a study from the National Toxicology Program suggested a correlation between elevated fluoride exposure and reduced IQ scores.
It is crucial to note that the fluoride levels examined in this study were double the federal limit for drinking water.
The study authors clarified that their findings do not definitively prove that fluoride causes lower IQ but rather establish a pattern between these factors.
The researchers stated: ‘Numerous substances are beneficial in small quantities yet potentially harmful in high doses. Further research is warranted to comprehensively understand the potential health risks associated with varying levels of fluoride exposure.’
Potential Public Health Implications of Fluoride Bans
Dr. Scott Tomar, a public health dentist and oral epidemiologist at the University of Illinois Chicago, expressed to The New York Times that the Utah law and similar potential bans could lead to increased dental health issues across the nation, particularly in lower-income communities.
He emphasized: ‘The advantages of community water fluoridation are most evident in low-income areas—communities that frequently have limited access to dental care and alternative fluoride sources.’
