A dental implant is a titanium post (like a tooth root) that is surgically positioned into the jawbone beneath the gum line that allows the dentist to mount replacement teeth or a bridge into that area. Implants are used to support a dental prosthesis (from single crowns to full denture) once the bone grows around the post.
A procedure in which a diseased, redundant, or problematic tooth is removed, either by pulling or cutting out. Permanent teeth may also need to be removed for orthodontic treatment.
Dental surgery is any of a number of medical procedures that involve artificially modifying dentition; in other words, surgery of the teeth and jaw bones. Impacted wisdom teeth usually require surgery for their removal.
