Diet for a Pretty Smile

Dried licorice root may fight tooth decay, new research has found. But if you're not a fan, these foods can also help keep teeth, gums, and breath healthy, says Mark Wolff, D.D.S., Ph.D., of NYU College of Dentistry:

Yogurt. The lactic acid may ward off periodontal disease, but skip the sugary varieties.

Sugar-free gum and hard candies. These promote saliva flow and also help fight cavities. Xylitol-sweetened ones work best.

Raw or firm vegetables. Chewing celery and other crunchy veggies helps "scrub" your teeth. Ones with vitamin C—broccoli; red, green, and yellow peppers—may also protect against gum disease.
