CHICAGO (AP) -- Illinois health officials say they'll wait before making any new recommendations on fluoride levels in drinking water across the state.

Fluoride is credited with cutting cavities and tooth decay. But studies show too much fluoride causes spots on some children's teeth. The federal government is planning to recommend lower levels of fluoride in water supplies. It's the first change in nearly 50 years.

Chicago Department of Water Management spokesman Tom LaPorte says the city generally aims to maintain fluoride levels at 0.9 to 1.05 milligrams per liter.

He says the water department is working closely with the federal and state Environmental Protection Agencies as they review the new recommendations.

Officials with the Illinois Department of Public Health said Friday the state's 1,850 water supplies follow current recommended fluoridation guidelines.
