Summary

Utah became the first state to ban fluoride in public drinking water after Republican Gov. Spencer Cox signed legislation prohibiting local decisions on fluoridation.

Cox cited cost and personal choice, likening fluoride to government “medication.”

The ban faces opposition from dentists and health experts, who argue fluoride prevents cavities and benefits low-income communities.

Nearly two-thirds of Americans receive fluoridated water. Some cities have already removed fluoride, and a recent court order requires the EPA to regulate high levels that may affect children’s intellectual development.
