Addition of fluoride to public drinking water prohibited.

Minnesota House Bill 3237 (HF3237) proposes to prohibit the addition of fluoride to public drinking water systems in the state. The bill defines 'fluoride' to include substances such as sodium fluoride, hydrofluoric acid, sodium fluorosilicate, and hydrofluorosilicic acid. If enacted, it would repeal existing statutes that mandate fluoridation of public water supplies. The bill was introduced on April 24, 2025, and referred to the House Health Finance and Policy Committee.

Supporters of HF3237 argue that removing fluoride from public water systems addresses health concerns associated with fluoride consumption and promotes individual choice regarding fluoride intake. They believe that this measure ensures the purity and safety of drinking water by eliminating the addition of chemical substances.

Opponents of HF3237 contend that prohibiting water fluoridation could lead to an increase in dental health issues, particularly tooth decay, as fluoride has been proven to prevent dental disease. They emphasize that community water fluoridation is a safe, effective, and equitable public health measure that benefits all residents, regardless of socioeconomic status.
