U.S. says too much fluoride causing splotchy teeth

ATLANTA – In a remarkable turnabout, federal health officials say many Americans are getting too much fluoride, and it’s causing splotches on children’s teeth and perhaps other, more serious problems.

The U.S. Department of Health and Human Services announced plans Friday to lower the recommended level of fluoride in drinking water for the first time in nearly 50 years, based on a fresh review of the science.

The announcement is likely to renew the battle over fluoridation, even though the addition of fluoride to drinking water is considered one of the greatest public health successes of the 20th century. The U.S. prevalence of decay in at least one tooth among teens has declined from about 90 percent to 60 percent.
