The crowning process usually takes two visits.
It typically takes a dentist two separate appointments to make and place a new dental crown for a patient.
The first appointment involves: 1) Preparing (shaping) the tooth, 2) Taking its impression and 3) Placing a temporary crown. The time needed to perform these steps can range from 30 minutes to an hour.
During the time period between the two appointments, a dental laboratory will fabricate the crown. Two weeks or so are usually allotted for this process.
When the patient returns for their second visit, the dentist will cement the finished crown into place. This step can usually be completed in about 20 minutes or so.
That means all of your appointments together, spaced about two weeks apart, will take somewhere on the order of an hour to an hour and a half of actual chair time.
