What happens when they put crowns in at the dentist?
Assuming no root canal was done, the dentist will numb you and then file down the tooth until it's just a small point. Then he'll take an impression of the area. You'll get a temporary crown right then, it's nothing fancy, just good enough to get you by. He then sends the impression to a lab, and depending on the lab, you should have the real one within 2 weeks. Then he cements the real one in. No novacaine is used now. Your gum line might be a little sore for a few days until you get used to it.
