Many people think of cavities as a dental health problem that affects mainly children, whose mouths are still developing and growing. However, as people age their bodies continue to change, making them susceptible to tooth decay as well. Older adults may find that their gums are receding from their teeth as part of the early stages of gingivitis, thereby exposing the roots of their teeth to plaque.

At the same time, bacteria may accumulate in the crevices and fractures around old dental fillings, which can result in tooth decay. Dental patients may already be aware of the importance of brushing and flossing on a daily basis for preventing cavities and maintaining dental health. An additional preventative measure may be taken by asking your dentist about applying a sealant – a thin plastic coating that creates a barrier between teeth and cavity-causing plaque.

Although sealants are most often applied to children’s teeth, they may also be effective for adults, according to the California Dental Association. Your dentist should be able to answer any questions about this procedure.
