A dental implant is an artificial tooth root that is surgically placed into the jaw to replace a missing or extracted tooth. The implant has an exposed piece called the abutment. A porcelain crown, bridge, or full denture is cemented on the abutment. Once attached, the implant functions as a natural tooth.
A dental extraction or informally called tooth pulling is the removal of teeth from the dental socket. Extractions are performed for a wide variety of reasons, such as extensive tooth decay, periodontal disease, or dental trauma, especially when they become painful.
