Temporary crowns are used to protect a prepared tooth while a permanent crown is being made. In some cases, the dentist may need to remove the nerve of the tooth before placing the temporary crown. This is done to prevent pain and discomfort. The nerve is located in the center of the tooth and is responsible for sending signals to the brain. When the nerve is removed, the tooth will no longer be sensitive to pain or temperature changes.
Removing the nerve of a tooth is a relatively simple procedure. The dentist will first numb the area around the tooth. Then, they will make a small incision in the gum tissue and remove the nerve. The procedure usually takes about 30 minutes. After the nerve has been removed, the dentist will place the temporary crown on the tooth.
