Well, that was fun. Two needles to freeze, as expected. The dentist (new to me) was good, very patient. Took over two hours all told. He did the prep work for the temporary crown, then left the assistant to do the actual temp crown. After I left the clinic, I had time before my bus so popped into the grocery store. I was at the cash, waiting in line, when I felt something in my mouth, spit it into my hand. Ha! It was the temporary crown... very temporary at less than 15 minutes. I was trying to hang onto it, but dropped it and then couldn't find it, in spite of getting down to look. Alas the floor is very similar in colour to that of normal teeth. Some janitor is going to find that and wonder.... It took a minute for me to realize that the tooth is singing! Fortunately, the clinic is very close to the grocery store, so back I went, where I waited for another temporary crown to be put on. This time the dentist did it. Fingers crossed it stays on...
