The debate over whether to continue fluoridating drinking water has reached Miami-Dade County, with differing views from healthcare professionals and political figures. Florida's surgeon general, Dr. Joseph Ladapo, recently argued against fluoridation, citing concerns about its potential negative effects on health, particularly cognitive function. He believes that after 80 years of fluoridation, the risks have become too significant to ignore, as reported by NBC Miami.
Dr. Ladapo and other experts, including University of Florida researcher Dr. Ashley J. Malin, argue that fluoridation is outdated and could be harmful. They point to studies suggesting that children fed formula could experience a decrease in IQ due to fluoride exposure, according to Dr. Malin in an NBC Miami report. Despite these claims, no decisions were made at a county safety and health committee meeting where this evidence was presented.
Miami-Dade’s water supply currently has fluoride concentrations adjusted to 0.7 milligrams per liter, in line with recommendations from the Centers for Disease Control and Prevention (CDC) to prevent tooth decay. However, some commissioners and dental professionals remain skeptical of the surgeon general's stance. Dr. Rick Mars, a local dentist, argues that many studies linking fluoride to health issues are flawed, supporting the consensus that fluoride is safe.
The issue also concerns Miami-Dade residents, such as Roger Terrone, who wants to ensure the safety and health of his family, "We have family, younger family members, I want to make sure their health is protected also," as he told NBC Miami.
The national conversation about fluoride has grown, especially after Robert F. Kennedy Jr., now secretary of Health and Human Services, raised the topic during his 2024 campaign, according to Health News Florida. Following this, the Florida Department of Health recommended that municipalities stop fluoridation, a policy already adopted in places like Utah.
Given the complexity of the issue, Miami-Dade commissioners are cautious about making changes to the county's fluoridation policy. Commissioner Marleine Bastien emphasized the need to review all research, noting that staff findings support the safety of low fluoride levels, as mentioned in an interview with Health News Florida. The county's current policy is influenced by the CDC's stance that fluoridation is an essential public health practice, a view upheld by many U.S. municipalities that provide fluoridated water to over 200 million residents.
