The U.S. Food and Drug Administration (FDA) today announced that it is initiating action to remove concentrated ingestible fluoride prescription drug products for children from the market. Unlike toothpaste with fluoride or fluoride rinses, these products are swallowed and ingested by infants and toddlers. They have also never been approved by the FDA. Ingested fluoride has been shown to alter the gut microbiome, which is of magnified concern given the early development of the gut microbiome in childhood. Other studies have suggested and association between fluoride and thyroid disorders, weight gain and possibly decreased IQ.
“The best way to prevent cavities in children is by avoiding excessive sugar intake and good dental hygiene, not by altering a child’s microbiome. For the same reason that fluoride may kill bacteria on teeth, it may also kill intestinal bacteria important for a child’s health,” said FDA Commissioner Marty Makary, M.D., M.P.H. “I am instructing our Center for Drug Evaluation and Research to evaluate the evidence regarding the risks of systemic fluoride exposure from FDA-regulated pediatric ingestible fluoride prescription drug products to better inform parents and the medical community on this emerging area. When it comes to children, we should err on the side of safety.”
