Besides looking virtually identical to your natural tooth and functioning just as well, an implant replaces a tooth without sacrificing the health of neighboring teeth, as might occur with a tooth-supported fixed bridge. This alternative requires your adjacent teeth to be ground down so they can support a cemented bridge.
Because a dental implant replaces the root of a missing tooth, it can preserve your bone structure. With a bridge, the bone that had surrounded the missing tooth begins to deteriorate. Single dental implants, on the other hand, integrate naturally with your jawbone, keeping it healthy and intact.
