As Utah prepares to stop fluoridating water in several systems, medical professionals are warning of the consequences and telling people how to keep their teeth healthy.

Florida lawmakers followed Utah’s example and passed a bill Tuesday banning the addition of fluoride to public drinking water. The bill is awaiting Republican Gov. Ron DeSantis’ signature after passing the Florida House 88-27.

Once enacted, the ban signed by DeSantis would make Florida the second state after Utah to outlaw the addition of fluoride to drinking water, a practice the Centers for Disease Control and Prevention called one of the great public health achievements of the 20th century.
