The Food and Drug Administration on Friday moved to limit the use of fluoride supplements that are meant to strengthen children’s teeth. This decision marks another step by Health Secretary Robert F. Kennedy Jr. and his team to reassess chemicals long considered standard in dental care. The FDA announced that these supplements should no longer be given to children under 3 years old or to older children who are not at a high risk of developing cavities. Until now, they had been prescribed for children as young as six months. The move follows a directive from the government’s Make American Healthy Again Commission to review the safety and benefits of these products.What Are Kids’ Fluoride Supplements?Fluoride is a mineral known to protect teeth from decay. It can be applied directly to the teeth, added to public water supplies, or taken in supplement form (known as systemic fluoride). It helps strengthen tooth enamel and shields it from the damage caused by plaque. Fluoride also supports the process of remineralization, which repairs the early stages of decay. These supplements are most often given to children.Now, according to CNN, the FDA has sent notices to four companies warning them of potential enforcement actions for marketing unapproved fluoride-containing ingestible drugs labeled for use in children under age 3, or in older children at low or moderate risk for tooth decay. The agency has also issued letters to healthcare providers, advising them to avoid prescribing these supplements for those groups.Why Is the Trump Administration Against Fluoride Supplements?Fluoride has drawn increased attention from the Trump administration following recent research that reopened discussions about the possible health risks of high fluoride exposure. Despite this, most experts continue to highlight the proven safety and dental benefits of fluoride. The United States began adding fluoride to public water systems in 1945 to make oral care more accessible and affordable. The Centers for Disease Control and Prevention later named water fluoridation one of the top ten public health achievements of the 20th century, alongside vaccines, family planning, and workplace safety improvements.According to federal data from 2022, most Americans live in areas where fluoride is added to the water. In regions where it is not, doctors often prescribe fluoride tablets or drops to help protect babies and children from cavities. However, this reliance on supplements could grow, as states like Utah and Florida have banned the addition of fluoride to public drinking water, and similar measures are being considered in several others.In April, the U.S. Department of Health and Human Services and the Environmental Protection Agency announced plans to reevaluate the science around fluoride and issue new guidelines. Health Secretary Robert F. Kennedy Jr. also said he would direct the CDC to stop recommending water fluoridation in local communities.A new scientific review released Friday concluded that fluoride supplements “should not be used in children under age 3 or by older children who are not at high risk of tooth decay.” The FDA added that “the same property that allows fluoride to kill bacteria on teeth may also affect the gut microbiome, which could have wider health impacts.”Why Do Dentists Recommend Fluoride Supplements?Dentists prescribe fluoride tablets, drops, and lozenges to children who live in places without fluoridated water or who are more likely to get cavities. This includes children with poor dental hygiene, those who skip regular dental visits, or those with family members who have dental disease. These supplements are meant to provide the same level of fluoride protection that fluoridated water offers.According to Dr. F. Perry Wilson, a physician and chronic disease epidemiologist at the Yale School of Medicine, fluoride drops and tablets deliver extra protection against cavities beyond what children get from toothpaste or mouthwash. Since these supplements enter the bloodstream and then the saliva, they help strengthen teeth from within, much like fluoridated water does, as reported by The New York Times.
