If you want to keep your teeth white, check this list of foods and beverages that stain teeth.

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
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
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.
Tips to Minimize Stained Teeth
Ironically, many of the foods and beverages that stain teeth are loaded with
antioxidants, which, of course, have key health benefits. So if you’re worried
about stained teeth, you might want to cut back on these foods and beverages
rather than cut them out entirely. “Moderation and a balanced diet are key,”
In addition, consider taking steps to minimize the contact between your
teeth and stain-promoting substances. Dentists offer several suggestions:
Use a straw. Sipping beverages through a straw is believed to help
keep teeth-staining beverages away from the teeth -- the front teeth, in
particular. No, you’re probably not eager to use a straw for coffee or wine.
But it shouldn’t be too much trouble to use a straw for cola, juices, and iced
Swallow promptly. Swallowing stain-causing foods and beverages
quickly is also believed to help protect teeth from stains. Obviously, it’s
important to chew foods thoroughly before swallowing. And gulping can, of
course, cause choking. But don’t retain things in your mouth for long periods
of time. In other words, savor flavors -- but not for too long. “There’s no
question that the quicker you drink something the lower the exposure [to
stain-promoting substances],” says Debra Glassman, DDS, a dentist in private
practice in New York City.
Swish with water. It’s not always convenient to brush your teeth
after having something to eat or drink. Even when it is, it might be better not
to: dental enamel is highly vulnerable to abrasion from tooth brushing for up
to 30 minutes after the consumption of an acidic food or beverage. So it’s
safer simply to swish with water -- and brush later, once the enamel has had a
chance to re-harden. Another way to remove stain-causing substances without
brushing, Howell says, is to chew sugarless gum after eating or drinking.
