Not to sound like a V.O. guy in a toothpaste commercial, but, do you have plaque? If you're not sure, check the bottom two front teeth in the center of your mouth, as it is there where it is typically most visible. How are you looking?

If the results of you quick self-exam are less than stellar, you're probably not alone -- studies show that one in five people admit to brushing their teeth less than twice a day. In addition to giving your teeth a good brushing more often, you can also try eating raisins. Researchers from the University of Chicago found that these tasty little fruits contain chemicals that prevent black from sticking to your teeth.

Of course, a trip to your friendly neighborhood D.D.S wouldn't be a bad idea, either. Oh, and at the end of your visit, when the hygienist offers you the choice of a complimentary tooth brush of roll of floss, go with the floss ... and unlike 72 percent of the rest of people living in America, do it every day.
