A dental bridge is, in some ways, less invasive and in other ways more invasive than a dental implant. Unlike implants, bridges do not replace a tooth root. Rather, a bridge uses one or more surrounding teeth as a support on which to attach a crown that can fill the missing tooth space. The treatment process is not nearly as long as the implant process (which requires osseointegration), though in some ways, it is more invasive because it requires the permanent alteration of adjacent teeth to support the bridge. As the name implies, a dental bridge literally bridges the gap between teeth resulting from a missing tooth. The restoration, therefore, must be anchored to one or more adjacent teeth, which must first be filed down in order to function as a support.
