I have permenant nerve damage from when I had my wisdom teeth out 10 years ago. Having the doctor "recheck" it proved to be a waste of time. I went in once a month for about 3-4 months and all he would do is poke around and ask what i felt. The last time I went he said he could try to do a nerve graft. There was no way I was risking it getting damaged more so I opted to wait it out.
At first, it was dead numb. Then it got extremely sensitive even to touch. They refer to this as "parathesia" Now I have partial feeling. I am told that part of the nerve regenerated but the rest did not. Fortunately I do not have drooping and barely notice it at all anymore.
The sharp shooting pain you felt was the needle touching or coming very close to the nerve. Nerves had electrical charges and metal and electric don't mix well. The shot he gave you is basically a blind shot - they aim for where the nerve typically is in text books and hope to get close enough that the anes will numb it. Typically you get a jolt and go numb very fast and it lasts a long time.
There is no reason to seek a dentist at this point. They can't do much unless you want to find someone who is willing to attempt to graft it but I don't think they would do that this soon after. Most of the time it regenerates but takes a very long time. It also doesn't mean that you had a terrible dentist. He had a good aim. Him stepping back and looking at you like "what is wrong with her" was probably because, believe it or not, not that many people freak out or cry in the chair and what you experienced doesn't happen that often.
To tryingourbest, Most dentists have you sign a consent form before performing an extraction. Or they can verbally tell you about the odds of this happening, or lie and say they did. Anytime you have a surgery where they cut you, they cut the nerves completely in half or in the case of extractions have a very good chance of at least nicking the nerve. I had a c-section and now my stomach is numb there, no one told me it would happen but I can't very well sue them, Basically, you have no case as far as suing them goes. I work in the dental field and have for 14 years, including some time in a oral surgery office. You both really need to find dentists who have a genuine concern about your dental health - sounds like both these offices don't really cares what happens after you walk out the door and any problems that arise are nothing but an inconvenience for them, rather than for you - not good. And I would seriously reconsider another surgery esp this soon after and by the same doctor. get a second opinion.
