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.
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.

Impressions will be made of your tooth and the surrounding teeth. This is to make sure that the new crown will not impact your bite. The impressions will be sent to a dental lab where the crown will be made.

You may have some pain when the local anesthetic is injected. After the procedure, you may have discomfort or sensitivity around your tooth.
