Fitting a crown usually requires two visits to your dentist.
During the first visit, the tooth is prepared for the crown. You'll be given an anesthetic. Once you're numb, your dentist will remove the outer portion of your tooth to accommodate the thickness of the crown. If the tooth has a filling, part of the material may be left in place to serve as a foundation for the crown.
An impression is then made to provide an exact model for the prepared tooth. This impression is sent to a laboratory for construction of the crown.
Once the impression is completed, your dentist will place a "temporary' crown on your tooth. This temporary crown is made of acrylic resins and will protect the tooth and gum tissue while the permanent crown is being formed - a process of one to two weeks.
During the second visit, the temporary crown is removed. Your dentist will then fit the permanent crown, check for accuracy, adjust for any bite discrepancies and evaluate for appearance. If all these factors are acceptable, the crown will be cemented to your tooth.
