Hi and welcome. What did your doctor think? I had an episode of TN several years back. I also went to the dentist, who found nothing dentally amiss. My doctor referred me to a neurologist, but it went away after a few days and I canceled the appointment. I hope it doesn't come back. And I hope yours goes away.
We do have a forum specific to TN if you haven't found it yet. Here's the link:
