Fluoride in Drinking Water to Be Reduced
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.
