Yes to both. The Trigeminal Nerve is the sensory nerve for the face and that includes the teeth. If you have a cavity, best to get it filled. You've probably already done that, but if not, contact the TNA (see numbers in previous posts) and you can ask them for a Professional Packet to give to your dentist with info about TN and how to treat you so as to minimize flares during and after treatment. Or go to the following links and print out the information -

Visit the sticky threads at the top of the forum and learn about TN from the websites listed there. There are other drugs that may work better for you and let you get back to a more comfortable life. Find another neurologist who is willing to work with you. Talk to some neurosurgeons. You need to do the research (unfortunately - hard when you're hurting so much, but don't take just one doctor's word as law). Get a copy of Striking Back (contacts listed in other threads) and learn what your options are.

Best to you and keep us posted.
