At every age, a healthy diet is essential to healthy teeth and gums. A well-balanced diet of whole foods — including grains, nuts, fruits and vegetables, and dairy products — will provide all the nutrients you need. Some researchers believe that omega-3 fats, the kind found in fish, may also reduce inflammation, thereby lowering risk of gum disease, says Anthony M. Iacopino, DMD, PhD, dean of the University of Manitoba Faculty of Dentistry.
Avoid sugary foods
When bacteria in the mouth break down simple sugars, they produce acids that can erode tooth enamel, opening the door to decay. “Sugary drinks, including soft drinks and fruit drinks, pose a special threat because people tend to sip them, raising acid levels over a long period of time,” says Steven E. Schonfeld, DDS, PhD, a dentist in private practice and spokesperson for the American Dental Association. “Carbonated drinks may make matters worse, since carbonation also increases acidity.” Sticky candies are another culprit, because they linger on teeth surfaces.
