British aren't sure they want fluoride in their drinking water

If you drink water from a municipal water source (not well water), then chances are good that fluoride has been added. It's a common practice in the U.S. to protect teeth from decay. British Health Secretary Alan Johnson wants the practice to become widespread in England -- only 10% have fluoridated water there -- but he's getting resistance from people who question the safety of fluoride and who also say it's their right too choose what goes into their water.

Some studies show that an excess of fluoride can actually pit the teeth and may affect bone health. But health experts say the benefits far outweigh the risks and that children who drink fluoridated water have 15% less tooth decay than those that don't.
