Too much of a good thing? Excess fluoride in water supply causes dental problems

For the first time in nearly 50 years, the government is recommending lowering the fluoride in drinking water. Officials say many Americans are getting too much fluoride and it's causing some kids to have "splotchy" teeth. The AP's Kelly Daschle reports.

The US health department is recommending that water supplies contain 0.7 milligrams of fluoride per liter of water, replacing the current recommended range of 0.7 to 1.2 milligrams.

Learn how much fluoride is in your tap water. Call your local water municipality because the level varies from city to city. If it's above 0.7 milligrams per liter, you could consider filtering your water.
