FDA Limits Fluoride Supplements for Young Children, Citing Safety Concerns
The Food and Drug Administration (FDA) announced today it is restricting the use of fluoride supplements for children, a move that could impact dental health strategies in areas with limited access to fluoridated water.
The FDA stated that fluoride tablets, lozenges, and drops are no longer recommended for children under the age of three, and for older children who are not at high risk of tooth decay. Previously, these supplements had been prescribed for children as young as six months old. The agency sent warning letters to four companies, directing them to market their products within these new limitations, stopping short of a full market removal initially suggested in May.
According to a new scientific analysis released by the FDA, fluoride supplements offer limited benefits and may be linked to potential health issues, including disruptions to the gut microbiome, weight gain, and cognitive effects. “For the same reason fluoride may work to kill bacteria on teeth, it may also alter the gut microbiome, which may have broader health implications,” the agency explained in a statement. This decision follows concerns raised by Health Secretary Robert F. Kennedy Jr., who has described fluoride as a “dangerous neurotoxin.” The Centers for Disease Control and Prevention maintains that fluoride strengthens teeth and has established guidelines for its use in public water systems since 1962.
The American Dental Association disputes the FDA’s claims, asserting that fluoride, when used as prescribed, does not pose significant health risks. However, dentists warn that restricting access to supplements could lead to increased cavities, particularly in rural communities lacking fluoridated water. The FDA’s actions do not affect fluoride toothpaste, mouthwash, or in-office dental treatments. The agency indicated it will continue to monitor the safety of fluoride products and assess the potential impact of these changes on public health.
