That's Fit

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.

We've all seen the ads for over-the-counter teeth whiteners, and I'll admit to being curious about them myself. I've never taken the leap, however, because I'm concerned about safety and the long-term health of my teeth. But then I read this article from the Seattle Times.

According to them, if the directions are followed closely and you don't try to whiten too frequently, then bleaching your teeth with an OTC whitener can be safe and effective. However, though these methods are inexpensive compared to having your dentist do the procedure, they don't last nearly as long -- one to six months, compared to six to twelve months when done professionally.

Additionally, OTC whiteners don't work on things like caps, crowns, veneers, or dentures, and they also aren't effective on certain stains. So if you're willing to accept those conditions and don't try to over-whiten your teeth, it appears to be a safe enough procedure.
