JK: he just pulled the nerve, left the tooth. Don’t ask me why. Then packed the now empty space with whatever goes in there to end up being called a root canal. Actually, I am pretty tolerant of dental pain in general. Frequently, if I have a minor cavity, I’ll have the dentist drill without numbing. I prefer 90 seconds of acceptable pain to dead feeling in mouth, cheeks, and jaw, for hours. However, the Swiss incident was not by choice.
