It would come on sudden, and leave sudden. My mouth would feel as though it was on
fire all around on
that side and on
that side of my tongue. We left the high altitude, highest of 10,000 ft. When we got below 4000 i felt some relief. Stopped and got an ice cream and even though i had gotten use to not letting anything cold or hot float over to those teeth, some melted ice cream did drift to that tooth area. Again, my face and mouth was on fire and stayed that way longer.
