One in 3 Florida 3rd Graders Have Untreated Cavities. Now a New Law Prohibits Fluoride in Water.

Florida ranks among the worst states in the U.S. for dental care access, with over 5.9 million residents living in dental care health professional shortage areas. a new Florida law, signed by Gov. Ron DeSantis in May 2025 and going into effect on July 1, now prohibits local governments from adding fluoride to public drinking water. This makes other preventive treatments even more essential. Fluoride varnish, recommended by pediatric and dental associations, is a topical treatment that should be applied every 3-6 months to reduce the risk of tooth decay.
