Is it really true that a general anesthetic is not required for implant placement?
Yes. The pain response in the jaw can be completely suppressed with a local anesthetic. When the implant site is drilled into the bone and the implant is screwed into place, you will feel a vibration and a slight feeling of pressure but no pain. For most patients the procedure feels like treatment for caries which is also conducted under local anesthetic. If you still want to sleep through the treatment nonetheless, just ask.
