Utah appears to be the first state ready to put a full ban on fluoride in public water systems under a bill that doesn’t allow cities or communities to decide whether to add the cavity-preventing mineral.

Republican Louisiana state Sens. Mike Fesi and Patrick McMath are sponsoring legislation prohibiting fluoridation of public water systems across the state.

A bill before the governor would prohibit adding fluoride to water systems. The move could affect children’s health, experts warned.
