US EPA Accelerates Review of Fluoride Safety in Drinking Water Under Trump Health Agenda

The U.S. Environmental Protection Agency has launched an expedited review of fluoride levels in drinking water, marking a significant shift in federal health and environmental policy under the Trump administration’s “Make America Healthy Again” (MAHA) agenda. A notice published in the Federal Register confirms that the agency has begun a fast-tracked toxicity assessment that could ultimately lead to revisions of national drinking water standards. According to the EPA, the final assessment will help determine whether current fluoride limits under the Safe Drinking Water Act remain appropriate and will also inform future guidance from the Centers for Disease Control and Prevention. The review follows a 2024 federal court order directing the agency to strengthen its evaluation of fluoride’s potential risks, particularly regarding children’s cognitive development. Reducing or eliminating fluoride in public water systems has become a core priority of the MAHA movement, which supports Health Secretary Robert F. Kennedy Jr. Kennedy has long opposed water fluoridation and has pledged to reverse CDC recommendations, despite the absence of scientific consensus supporting his claims. In May, the Food and Drug Administration moved to withdraw fluoride supplements for children, signaling growing momentum behind the agenda. The EPA said the review will focus exclusively on potential harms, including impacts on brain and tooth development, and will not consider fluoride’s dental health benefits. This approach has drawn concern from public health advocates, as organizations such as the American Dental Association continue to support fluoridation, citing evidence that it reduces tooth decay by more than 25%. The agency will open a 30-day public comment period, followed by external peer review, as pressure mounts on EPA leadership to further align environmental regulation with MAHA priorities on chemical exposure and public health.
