Fluoride in the Phoenix water supply

Putting fluoride in the public water supply began in earnest in the U.S. in the mid-20th century. The process was intended to reduce tooth decay and help lower-income people who found it more difficult to afford regular visits to the dentist.

Most reputable studies have concluded that water fluoridation continues to accomplish those goals, but some groups remain concerned about the safety. Earlier this summer, researchers from the Harvard School of Public Health and China Medical University say they found indications that fluoride may affect cognitive development in children.

It was against that backdrop that a Phoenix City Council subcommittee heard testimony yesterday on whether to recommend changes to the city’s current water fluoridation process. But after two hours the council subcommittee decided not to recommend changes.

The guest to discuss the hearing and fluoride in water is Dr. Bob England, Director of Maricopa County’s Public Health Department. Opponents of water fluoridation did not make a guest available to us.
