Aren't Cavities Just Kid's Stuff?
No. Changes that occur with aging make cavities an adult problem, too. Recession of the gums away from the teeth, combined with an increased incidence of periodontal (gum) disease, can expose tooth roots to plaque. Tooth roots are covered with cementum, a softer tissue than enamel. They are susceptible to decay and are more sensitive to touch and to hot and cold. The majority of people over age 50 have tooth-root decay.
Decay around the edges, or margins, of fillings is also common to older adults. Because many older adults lacked benefits of fluoride and modern preventive dental care when they were growing up, they often have a number of dental fillings. Over the years, these fillings may weaken and tend to fracture and leak around the edges. Bacteria accumulate in these tiny crevices causing acid to build up which leads to decay.
