Want whiter and brighter teeth? Look no further than your food. Grab an apple, some carrots, a cucumber now and then and you'll scrub your stains away. It's the abrasive or crunchy quality of these foods that do the trick, says Elisa Mello, DDS, a cosmetic dentist in New York City. Items to avoid: Red wine, coffee, and cola, which may darken your pearly whites.

Another cleaning trick, says Mello for Woman's Day magazine (July 8, 2008), is to sip staining beverages through a straw and then chase with plenty of water to prevent them from leaving a mark.
