So, one dentist (not the one I usually see, but his associate) and 2 technicians worked for an hour trying to replace the temporary crown that broke yesterday and I was finally advised just to go without until my permanent crown goes in Tuesday (or Monday if I get lucky). I'm having to eat very carefully and avoid very cold things because of the sensitivity. In a dental history that includes a lot of crowns, including my 4 front teeth, this is a first.
