Talk to your dentist about these risks before the procedure.
What to Expect TOP
Prior to Procedure
It typically takes 2 visits to have a crown placed. Before these appointments, you and your dentist will decide which type of crown is best for you. Different materials are used to create crowns:
You will also have dental exams. The dentist will evaluate the health of your tooth's roots.
It is also important that you talk to your dentist if you take any medications, herbs, or supplements. You may need to stop taking some medications up to 1 week before the procedure.
In addition, tell your dentist if you have any heart conditions or joint replacements. You may need to take antibiotics to prevent infection.
Local anesthesia will be used.
Description of the Procedure TOP
The First Visit
The area surrounding the tooth will be numbed, usually by injecting a local anesthetic into the gum. Next, the tooth will be prepared for the crown. The surfaces will need to be filed down. If you are missing part of the tooth, material may need to be added to the tooth so that the crown can be placed. This filling material is called a crown buildup.
Physical impressions will be made of your tooth and the surrounding teeth. This is to make sure that the permanent crown will be an exact fit without impacting your bite. The impressions will be sent to a dental lab where the permanent crown will be made. If you are planning to have a porcelain crown, the dentist will help you select a shade that looks like your natural tooth color. The dentist will put in a temporary crown until the permanent one is ready. The permanent crown should be ready in 2-3 weeks.
A newer technique uses digital technology to take impressions. This allows a permanent crown to be made in the office in 1-2 hours. This technology may not be available everywhere.
The Second Visit
If had a temporary crown placed, you will need to return for a second visit. The dentist will numb the area again. The temporary crown will be removed. Cement will be used to secure the new permanent crown in place.
How Long Will It Take? TOP
You will need to have about 2 visits over the course of several weeks. Each visit may last about 30-60 minutes.
Will It Hurt? TOP
You may have some pain when the local anesthetic is injected. After the procedure, you may have discomfort or sensitivity around your tooth for a short time.
