An impression is taken and a temporary crown is placed over the top of the prepared tooth. The impression is sent to the laboratory and the crown is then fabricated. The next appointment usually between 2-3 weeks later involves cementing the permanent crown in place. If all goes well, this appointment takes 30 minutes.
A RealAge answered. Crowns, which cap a tooth that is too damaged to hold a filling, are expected to last about five to eight years. Many last much longer, though. Your dentist will check your crown at regular checkups, and if it is still working well, you may be able to keep it for many years. On the other hand, if you regularly grind your teeth, chew on ice, or bite your fingernails, your crown may need to be replaced even before five years is up.
