Keep Your Gums and Teeth Healthy.

Good oral hygiene like brushing and flossing at least twice every day can help prevent gum infections, cavities, and tooth loss. Having your teeth cleaned and checked by a dentist or dental hygienist at least once a year also is important, the IDA says. No matter how well you brush, tartar and plaque can still build up and cause gum problems. The foods you eat contribute to tooth decay when they combine with bacteria in your mouth. To protect your teeth: Have plenty of calcium-rich foods such as milk, yogurt, and cheese. Calcium maintains the bone the tooth roots are embedded in. This is particularly important for older adults and for children during the development of both baby and adult teeth. Donot eat sticky sweets, such as soft candies, toffees, taffies, and pastries. If you eat sweets, rinse your mouth with water afterward. Or brush your teeth if you have a chance. If you chew gum, chew sugar-free brands.
