Utah Becomes First State to Ban Fluoride in Public Water Systems

Governor Spencer Cox signed the legislation, effective May 7, 2025, citing limited health differences in fluoridated areas despite opposition from major health organizations.

The law prohibits individuals and local governments from adding fluoride to public water systems or enacting fluoridation ordinances.
Utah Governor Spencer Cox justified the decision by pointing to the lack of significant health disparities between residents with and without fluoridated water.
Major health organizations, including the CDC and ADA, oppose the ban, emphasizing fluoride's proven benefits in reducing cavities and improving dental health.
Critics warn the ban could disproportionately harm low-income communities that rely on fluoridated water for affordable dental care.
The legislation allows pharmacists to prescribe fluoride supplements, offering an alternative to community water fluoridation.
