1. Go On a White-Teeth Diet
What goes into your mouth shows up on your teeth. So if you’re drinking a lot of red wine or black tea, or smoking cigarettes, expect the results to show up as not-so-pearly whites. Other culprits include colas, gravies and dark juices. The bottom line: if it’s dark before you put it in your mouth, it will probably stain your teeth. Step one: brush your teeth immediately after having foods that stain. Step two: regularly use a good bleaching agent from your dentist. Step three: be conscious of tooth-staining foods and drinks, and have them only when a toothbrush is around. If not, have an apple for dessert.
