Dental implants are artificial tooth roots that are placed into the jawbone to support a replacement tooth or bridge. They are made of titanium, which is biocompatible with the human body, and they can be used to replace one or more missing teeth. Dental implants are typically placed by a dentist or oral surgeon and the procedure is performed under local anesthesia. After the implants are in place, the replacement teeth are attached to the implant, completing the restoration. Dental implants are a permanent solution for missing teeth and can help to improve an individual's oral health and appearance.
