A dental implant is a small metal or titanium rod that is screwed into the jaw bone and then capped with a crown. The dental implant is used to replace a tooth or teeth that have been lost due to damage or decay. Dental implants prevent teeth on either side of an opening from shifting away from other teeth that are nearby. When implants are used, they act as a barrier that the other teeth can butt up against, holding them in place and maintaining the mouth’s original alignment. Dental implants are often put in as soon as the root of the other tooth is removed to ensure the other teeth remain in place.
