A: Replacing missing teeth has always been a challenge for dentists, but fortunately we have added another way to replace teeth that offers many advantages over conventional methods. Dental implants allow a missing tooth to be replaced without altering or trimming down neighboring teeth that would serve as anchors for a bridge, or without relying on neighboring teeth that are not strong enough to support a bridge. Partial dentures and full dentures can be supported or retained by implants so that the function of the denture is greatly improved. The problem of a lower full denture that moves around when talking or eating can often be corrected by placing two implants in the lower jaw that hold the denture in place. Once dental implants are placed, the gradual deterioration that takes place in your jawbone where teeth are missing is slowed or eliminated.
