I get the same pains. I always have a lot of jaw pain, almost like I have too many teeth in my mouth and there's pressure there. The pain goes from up by my ears to the top and bottom of my jaw, right round both sides of my face.

I recently had to have some teeth out so they did extra local at the start and the end of the procedure to help with the pain and it all worked well. I was worried about problems from all the sympathetic nerves in my face but it was all fine.
