A dental implant is a tooth restoration for people who are missing one or more teeth for a variety of reasons, like injury or periodontal disease. To begin the implant process, a metal post is surgically positioned into the jaw. Once it is in place and the bone surrounding the implant has had time to heal, a replacement tooth is attached to the post. Implants are stronger than natural teeth and generally last 10-20 years. They are also a more favorable approach than bridgework, because they do not depend on neighboring teeth for support.
