Too much fluoride damages kids’ teeth, study shows

Posted by Trish Riley, January 21, 2011

Less fluoride in drinking water wouldn't lead to more tooth decay, say state and local dentists, experts and their professional organizations.

Concerned about the effects of excessive fluoridation, the federal government is proposing to lower the amount of fluoride recommended in drinking water. The current acceptable range is 0.7 to 1.2 milligrams per liter of water. The proposed fluoride level would be an optimal 0.7 milligrams of fluoride per liter of water.

It’s the first change that the U.S. Department of Health and Human Services has proposed since recommendations were set in 1962. Water districts add fluoride to the water supply to promote dental health care through a process called fluoridation.
