You will typically have two visits to the dentist to prepare for a dental crown. In some cases, your dental crown can be made in your dentist’s office.
The first visit
During the first visit, the tooth that’s going to receive the crown is examined and prepared. X-rays of the tooth and its surrounding bone will be taken. Your dentist might have to do a root canal treatment before your dental crown procedure if there is any:
-> Tooth decay.
-> Risk of infection.
-> Injury to the tooth’s pulp which is the soft tissue inside your teeth that contains blood vessels, nerves and connective tissue.
The tooth that is receiving the crown will be filed down across the top and sides. This will make space for the crown itself. The amount of tooth that gets filed away depends on the type of crown you have. All-metal dental crowns are thinner and will not need as much of the tooth removed as compared to all-porcelain or porcelain-fused-to-metal crowns. If too much of your tooth is missing — due to damage or decay — a filling material can be used to “build up” enough tooth structure for the crown to cover.
After reshaping the tooth, a paste or putty is used to make a copy (also called an impression) of the tooth that’s going to receive the crown. Impressions of the teeth above and below the tooth that’s getting the dental crown will also be made. This is done to make sure that the crown will not affect your bite.
The impressions are sent to a dental laboratory. The laboratory makes the crowns and usually returns them to the dentist’s office in two to three weeks. During this first office visit, your dentist will make a temporary crown to cover and protect the prepared tooth while you are waiting on the permanent crown.
The second visit
During the second visit, the permanent crown is placed on your tooth. The temporary crown from your first visit is removed and the fit and colour of the permanent crown is checked. If everything is suitable, a local anaesthetic is sometimes used to numb the tooth and the new crown is permanently cemented in place.
Same-day dental crowns
Dental crowns can also be made on the spot by your dentist if he or she has the equipment. This process starts off similarly to the traditional way a crown is made — the first steps are to remove decay and shape the tooth for a perfect fit inside the crown. After these steps, the actual making of the crown is different. In the same-day procedure, a scanning device (a “wand”) is used to take digital pictures of the tooth inside your mouth. The computer’s software creates a 3D model of the tooth from these pictures. The digital design is then sent to another in-office machine that carves the shape of the crown out of a block of ceramic. In less than 15 minutes, the crown is ready to be cemented into place.
