I got Atypical TN after dental work. I've had it a good year. I am on meds. The medication has helped. Recently, I feel better...after enduring a good year of horrible pain. Even now, a cold wind will set the bad pain off. So for me, it hasn't stopped...it is still there. I rely on the meds to keep the pain away.

Regarding your situation....I'm thinking a dental procedure can definitely set if off or off again, especially in someone prone to this problem.

I hope you can get on meds to control it and I'm thinking since it has stopped before, it will stop again.
