Chew on This: 8 Foods for Healthy Teeth

Regular brushing and flossing help keep teeth healthy by getting rid of sugars and food particles that team up with bacteria to form plaque. Plaque produces acid that damages tooth enamel, causes cavities and sets the stage for periodontal, or gum, disease.

Now, a growing body of research is finding that certain foods may be good for teeth, too. Just as so-called “functional foods” may keep your heart healthy, for instance, others may promote oral health, according to Christine D. Wu, a pediatric dentistry researcher at the University of Illinois at Chicago.

Here are eight teeth-friendly foods that show promise.

Tea: Compounds called polyphenols, found in black and green teas, slow the growth of bacteria associated with cavities and gum disease. Researchers at the University of Illinois at Chicago found that people who rinsed their mouths with black tea for one minute, 10 times a day, had less plaque buildup on their teeth than people who rinsed their mouths with water. What’s more, the size and stickness of their plaque was reduced.

Cheese: Research published in the journal General Dentistry earlier this year reported that 12- to 15-year-olds who ate cheddar cheese had lower acid levels in their mouths than those who ate sugar-free yogurt or drank a glass of milk.

Raisins: Naturally sweet, raisins don’t contain sucrose, or table sugar. Sugar helps bacteria stick to the tooth surface, letting them produce plaque, Wu said. Raisins are also a source of phytochemicals, which may kill cavity-causing plaque bacteria. Some compounds in raisins also affect the growth of bacteria associated with gum disease, Wu has found.

Crunchy foods: It takes serious chewing to break down foods such as carrots, apples and cucumbers. But all that crunching isn’t in vain. Chewing “may disturb dental plaque, and serve as a cleansing mechanism,” Wu said.  So instead of remaining in your mouth and settling on teeth, bacteria get cleared away.

Vitamin-rich foods: Foods containing calcium — such as cheese, almonds and leafy greens — and foods high in phosphorous — such as meat, eggs and fish — can help keep tooth enamel strong and healthy, according to the American Dental Association.

“Acidic foods and beverages may cause tiny lesions on tooth enamel,” Wu said. “Calcium and phosphate help redeposit minerals back into those lesions.” Calcium is also good for bones, including your jaw.

Sugarless gum: Pop a stick in your mouth after eating. Chewing boosts saliva secretion, clearing away some bacteria, Wu said. The keyword here is “sugarless.” Bacteria rely on sucrose to produce plaque, Wu said.

Milk: In a study published in the Journal of the American Dental Association in July, Wu and her team found that drinking a glass of milk after downing dry, sugar-sweetened Fruit Loops lowered levels of acid in the mouth more than drinking water or apple juice did.

Cranberries: Cranberries contain polyphenols (just as tea does), which may keep plaque from sticking to teeth, thus lowering the risk of cavities, according to a study published in the journal Caries Research. A caveat: Because the fruit is so tart, many cranberry products have added sugar, which may affect any potential benefits for teeth, Wu said.
