AP EXCLUSIVE: US says too much fluoride in water
(AP) – 1 hour ago
ATLANTA (AP) — Fluoride in drinking water — credited with dramatically cutting cavities and tooth decay — may now be too much of a good thing. It's causing spots on some kids' teeth.
A reported increase in the spotting problem is one reason the federal government will announce Friday it plans to lower the recommended limit for fluoride in water supplies — the first such change in nearly 50 years.
About 2 out of 5 adolescents have tooth streaking or spottiness because of too much fluoride, a surprising government study found recently. In some extreme cases, teeth can even be pitted by the mineral — though many cases are so mild only dentists notice it.
Health officials note that most communities have fluoride in their water supplies, and toothpaste has it too. Some kids are even given fluoride supplements.
The U.S. Department of Health and Human Services is announcing a proposal to change the recommended fluoride level to 0.7 milligrams per liter of water. And the Environmental Protection Agency will review whether the maximum cutoff of 4 milligrams per liter is too high..................
