LOS ANGELES --
The federal government has called for a reduction in the amount of fluoride in drinking water because of a growing epidemic of fluorosis.Fluorosis is a tooth disease which stains and even erodes teeth and happens when someone receives too much fluoride, according to the U.S. Department of Health and Human Services and the U.S. Environmental Protection Agency.
According to the government, as much as 40 percent of children have fluorosis.
As a result, the government proposed the recommendation be set at no more than .7 milligrams of fluoride in every liter of drinking water.
That number is down from 1.2 milligrams per liter.
