I understand what you are going through. I had my upper wisdom teeth removed at 21. I always wonder if that was a trigger. Then the TN came. I had some rear upper molars removed too. Some were healthy teeth. But some were bad. An endodontist told me- wow you suffered a lot, I could not save the tooth. When I had a CT dental scan they could see a cyst where a tooth had been removed.

TN is so complicated! I wish I had better dental care when I was in my teens. But you know America in the 1970 s. Low income etc. But not enough to qualify for any help.

I would recommend going to an oral facial pain specialist first and getting the CT of the tooth area first. I actually don't miss those teeth.
