Should adults be concerned about cavities?

Tooth decay is not just a child’s problem. Adults of all ages can have cavities, too. The causes for tooth decay are the same for everyone, regardless of age. Decay results when the bacteria in plaque feed on the carbohydrates (sugar) in our diet to produce acids that can cause cavities.

Yet, the nature of the decay problem does change somewhat as people grow older. Adults are more likely to have decay around older fillings, and because many adults grew up without the benefits of fluoride, they may have many more fillings. Decay of the tooth root is also common among older adults. Root caries (decay) occur when the gums recede, exposing the softer root surface, which decays more easily than tooth enamel.

Tooth decay is also promoted by dry mouth. This condition—called xerostomia—occurs when the supply of saliva is greatly reduced. It can be caused by many types of medications (such as anti-histamines, anti-hypertensives, and anti-depressants) or radiation therapy to the head or neck. Saliva is needed to lubricate the mouth, wash foods away and neutralize the acids produced by plaque. Allowed to continue, dry mouth can lead to rampant tooth decay. If you think you have this problem, be sure to discuss it with your dentist or physician. They may recommend an artificial saliva and fluoride products to help prevent decay.
