Hi and welcome to the NeuroTalk Support Groups.

I'm so very sorry that you've been in so much pain. Frankly I can't imagine having a root canal with all that going on. Ouch. I hope you're able to delay something like that until you find some answers.

I can't help either but will make a couple of suggestions.

You could post in the Dentistry and Dental Forum and/or the Trigeminal Neuralgia Forum

Unfortunately neither are particularly busy forums but you never know, someone may be, or have been in the past, experiencing similar problems.

I did run a quick search using keywords "Trigeminal Neuralgia tooth" and came up with quite a list of old posts. If you have time you might want to try that.

Advanced Search Feature

Some of the posts I found sounded similar to the pain you have experienced.
All the best to you.

p.s. If you want to, you could ask a moderator if you could change your Username from your email address for privacy reasons.
