SDN Members don't see this ad. (About Ads) Help! I'm pre-dent and just got hired as a dental assistant, to be trained on the job. But the assistant who has been training me won't be there on Monday, and the office is currently understaffed. The dentist has very high expectations, and I want to be as prepared as possible, to minimize the crashing and burning. Could someone list a general step-by-step for a crown prep? "...then the dentist will probably do some drilling, and next is cord packing...." Like that. It would be absolutely appreciated!
