Florida Governor Ron DeSantis signs a ban on fluoride, prompting questions about the future implications for public health and water safety.
TALLAHASSEE — On Thursday, Florida Governor Ron DeSantis enacted a pivotal piece of legislation that prohibits local governments from adding fluoride to drinking water. Although the bill does not explicitly mention fluoride, it effectively bans local authorities from introducing any substances into the water supply that do not contribute to improving water quality or reducing contaminants.
This legislative action has drawn criticism from leading health organizations, which warn that the ban could have detrimental consequences for public health. Health experts emphasize that fluoride is both safe and beneficial in preventing dental decay, and its elimination could exacerbate oral health issues across communities.
Governor DeSantis framed the bill as an issue of personal choice, asserting that it empowers individuals to make informed decisions about their health. He expressed concerns that medical professionals might presume to dictate health matters without consulting the individuals affected.
Beginning on July 1, local governments in Florida will no longer be able to add additional fluoride to water, a preventive measure used for decades to combat tooth decay. Generally, most natural water sources contain varying levels of fluoride, quantified in parts per million (ppm). For optimal oral health, health officials have long recommended maintaining fluoride levels around 0.7 mg/L. For instance, in Pinellas County, fluoride concentrations typically span from approximately 0.15 to 0.50 ppm.
Currently, around 100 water systems across Florida provide fluoridated water, including extensive systems in Hillsborough and Pinellas counties, as well as the cities of Clearwater, St. Petersburg, and Tampa. Even prior to this statewide mandate, debates over the necessity and safety of water fluoridation have led some municipalities to consider halting the practice. In recent months, at least 14 local governments made the choice to discontinue fluoridation, impacting close to 1 million residents. Notably, the Miami-Dade County Commission enacted measures to continue fluoridation after a contentious veto by the county mayor.
The movement against fluoridation garnered increased momentum following the tenure of President Donald Trump, particularly after Robert F. Kennedy Jr. was appointed Secretary of Health and Human Services. Kennedy has publicly commended DeSantis for his actions, evoking themes of personal autonomy in discussions surrounding health choices.
Florida’s Surgeon General, Joseph Ladapo, has also taken a strong stance against fluoride, advocating against its use and addressing public concerns regarding potential health side effects through statewide outreach efforts. His recommendation against water fluoridation is significant, given his role as a public health authority.
Expert opinions within the dental community, however, largely support fluoride as a safe and effective means of protecting against tooth decay. Dr. Margherita Fontana, a prominent figure in dental science at the University of Michigan, contends that research opposing fluoride often stems from flawed data or international studies that include variables unrelated to fluoride exposure. She warns that reducing fluoride availability could lead to increased rates of dental decay, particularly among children.
Despite the anticipated implications of this legislation, the Food and Drug Administration (FDA) plans to address fluoride in another context by removing ingestible fluoride supplements for children from the market. This action underscores a broader conversation about the safety, regulation, and public perception of fluoride in both medicinal and public health contexts.
As Florida prepares for this significant shift in public health policy, the implications for community dental health and individual choice will unfold in the months ahead.
