Food For thought: Top List of ‘Culprits’ That Stain Your Teeth

White smile1. Wine. Red wine, an acidic beverage that contains chromogens and tannins, is notorious for staining teeth. But white wine, too, promotes staining. In a study conducted recently at New York University School of Dentistry, teeth exposed to tea were stained more severely if they previously had been exposed to white wine. So if you’re fond of following up that glass of Chardonnay with a cup of Earl Grey, you may be giving your teeth a double whammy.

2. Tea. Like wine, the ordinary black tea most people drink is rich in stain-promoting tannins. Dentists say it’s a bigger stainer than coffee, which is chromogen-rich but low in tannins. “Tea’s pretty aggressive,” says Mark S. Wolff, DDS, PhD, chairman of the department of cariology and comprehensive care at New York University School of Dentistry in New York City. Herbal, green, and white teas are less likely to stain than black tea.

3. Cola. Acidic and chromogen-rich, cola can cause significant staining. But even light-colored soft drinks are sufficiently acidic to promote staining of teeth by other foods and beverages. “Carbonated beverages have similar acidity to battery acid,” Messina says, adding that cola-stained teeth are most common among “people who have a can on their desk all the time and sip all day long.”

4. Sports drinks. Recent research led by Wolff found that highly acidic sports drinks can soften tooth enamel — setting the stage for staining.

5. Berries. Blueberries, blackberries, cranberries, cherries, grapes, pomegranates, and other intensely colored fruits (and juices, pies, and other foods and beverages made from them) can cause stains.

6. Sauces. Soy sauce, tomato sauce, curry sauce, and other deeply colored sauces are believed to have significant staining potential. 

7. Sweets. Hard candies, chewing gum, popsicles, and other sweets often contain teeth-staining coloring agents. If your tongue turns a funny color, dentists say, there’s a good chance that your teeth will be affected, too. But unless they are consumed regularly, these sweets probably play a minor role in teeth staining, says Maria Lopez Howell, DDS, a dentist in private practice in San Antonio.
