Florida has passed a new law banning fluoride from public water. Governor Ron DeSantis says people should have the choice to use fluoride and not be forced to get it through their tap water. Supporters of the ban worry about possible health risks from too much fluoride and believe people should decide for themselves.

Fluoride has been added to drinking water since the 1940s to help prevent cavities. Health experts say it keeps teeth strong and helps avoid tooth decay. The Centers for Disease Control and Prevention even called it one of the greatest public health successes of the 20th century.

Dentists warn the ban could lead to more dental problems, especially in children. Many groups tried to stop the law, but it will go into effect on July 1. Other states and cities may follow, and federal health agencies are reviewing their own guidance on fluoride use.
