Fluoridation Debate Intensifies as RFK Jr. Advocates for Removal from U.S. Water Systems

The long-standing public health practice faces scrutiny over safety and effectiveness, reigniting discussions on its benefits and potential harms.

Robert F. Kennedy Jr., recently appointed to a U.S. health department role, has called for the removal of fluoride from public water systems, citing health concerns including developmental risks and neurotoxicity.
Fluoridation, introduced in the mid-20th century, has been credited by the CDC as one of the greatest public health achievements, reducing cavities by approximately 25% in children and adults.
Critics argue that much of the evidence supporting fluoridation is outdated, with some studies suggesting limited contemporary data on its efficacy and concerns over potential adverse effects like dental fluorosis and skeletal issues.
A federal court ruling has prompted the EPA to reassess the safety of fluoride levels in drinking water, leading some U.S. water systems to halt fluoridation while awaiting further findings.
Proponents emphasize fluoridation's role in reducing dental health disparities, particularly for low-income communities, while opponents call for more rigorous, updated scientific evaluations.
