Dental Health and Fluoride Treatment
Where Can I Find Out How Much Fluoride Is in My Tap Water?
To find out how much fluoride is in your tap water, ask your local dentist, contact your local or state health department, or contact your local water supplier. Information for contacting your local water supplier should be on your water bill or see the "local government" section of your phone book.
Approximately 62% of the U.S. population served by public water supplies has access to adequate levels of fluoride in their water, and 43 of the 50 largest U.S. cities have water fluoridation systems.
