Hi. i have bilateral facial numbness and some pain with it. Have been told it is neuropathic pain, not TN. I'm a bit of a worrier and thought i would post as i have toothache, x-rays appear fairly normal but i have a large silver filling of 10 years and dentist thinks it may be worth taking the filling out though also said it is so close to the nerve that it may need root canal treatment. My fear is of the anaethetic or the root canal treatment making my neuropathic pain worse. Anyone have any knowledge of risks involved with this? I have read a lot about the possible link with dentistry and facial pain.
