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.

The Republican-controlled statehouse sent the bill to the desk of Gov. Spencer Cox (R) last week after it passed both chambers largely along party lines.

Fluoride will be banned from Utah water systems by May 7, if Gov. Spencer Cox signs a bill now headed to his desk.
