nerve damage after dental implant

Three weeks ago i had an implant placed in my mouth on tooth #30 on the right side of my lower jaw. Unfortunaltely my dentist drilled to far with the implant prep drill and nicked the inferior alveolar nerve. I felt a electric shock sensation when this happened and he immedialtey back it off. He then proceeded to extract tooth #31. The roots of that tooth were very close to the nerve canal but he feels the injury occurred with the implant drill. I now have altered sensation and numbness on my lower lip, chin as well as gums and teeth. My dentist informed me that nerves heal slow and this might take weeks months or even a year. He cant even guarantee ill ever get feeling back. The tightness in my lower right teeth is the hardest thing to deal with right now. I feel a lot of pressure and tightness there. Ibuprofen is helping somewhat. > > My current dilemma is trying to decide whether or not to remove the existing implant that he was then able to install. We confirmed the next day by 3d Cone Beam scan that the implant he installed is not violating the nerve canal so his recommendation was to leave it in. I would rather leave it in and not risk causing more damage to an already injured nerve. The confusing part is when i got a second opinion from a different dentist he advised me to take the implant out. He did not even want to see any imaging or film. My question is if its not violating the nerve canal what is the harm in leaving it in? He acknowledge that there is no physical impingement to the nerve from the implant but wont elaborate further about why to remove it. I just don't know whether to leave it in or take it out. Is it possible that the tightness i fell in my teeth is a result of the implant or the initial nerve damage itself? I just want to make sure i do the right thing and give myself the best opportunity to heal. Its been a real challenge coping with this. I'm having a hard time finding someone with expertise with this type of injury. Any guidance you can give me would be greatly appreciated. > Thank you > Mike Perkin
