While you may not be getting any older, your teeth probably are! Dental treatment and needs begin to change as you age. Adults can be divided into two distinct categories with respect to their needs: those adults who have not had a history of many restorations (fillings) and those who have had their teeth drilled and filled repeatedly over the years.
The first group is lucky. New decay can begin at any time, but the older you get, the less likely you are to get new cavities. If those adults, who have had few fillings, brush and floss their teeth properly so that they prevent periodontal disease, they probably will have few new dental problems develop. The old restorations they have had placed, will usually be replaced at infrequent intervals (especially if the fillings are only small fillings) and will not need many crowns (caps), bridges, implants or endodontic treatment (root canal therapy).
