Root canal treatments are performed when there is damage and infection on the nerve of your tooth. Rather than extracting the tooth entirely, a root canal treatment allows you to keep your natural tooth. Your dentist can identify a need for a root canal treatment through dental x-rays or other changes to your tooth by looking for abscesses.
The procedure begins with a local anaesthetic. After freezing the gums surround the tooth, the dentist drills into it and enlarges the root canal system. Using fine instruments your dentist will clean out the dead or infected tissue. After it has all been removed the root canals are plugged and the tooth is filled with a permanent material. The procedure ends with a cap being placed on top of the tooth to restore natural tooth function and appearance.
The crowned tooth should be treated as a natural tooth and follow the same oral care routine when being cleaned.
