U.S. health regulators are planning to phase out fluoride-containing supplements used to strengthen children's teeth due to potential risks associated with their ingestion. The FDA will conduct a review of these products with the goal of removing them from the market by late October. Concerns have been raised about the impact of excess fluoride intake on gut bacteria and potential health risks, prompting this regulatory action. The move comes amid ongoing debates about the safety and benefits of fluoride in dental care, with some experts advocating for its continued use in certain populations.
