Go on a white teeth diet
If youre quaffing red wine and black tea, or smoking cigarettes or cigars, expect the results to show up as not so pearly whites. Other culprits to blame for dingy teeth include colas, gravies, and dark juices. Bottom line: If its dark before you put it in your mouth, it will probably stain your teeth. Brush immediately after eating or drinking foods that stain teeth and use a good bleaching agent, either over the counter or in the dentists office. For convenient teeth cleaning action, eat an apple.
