Root Canal Therapy (Endodontics)
 |
In this example, the red spot indicates an exposed pulp, after decay removal |
 |
A root canal is done when the pulp, or nerve, is damaged. In this case, a deep cavity has invaded the pulp. |
 |
The decay is removed, and then the pulp tissue is cleaned out. This is comfortably done with a local anesthetic. |
 |
The canal space(s) are sealed with a rubbery material to prevent infection. |

The tooth is restored, often with a post and crown. The crown here is depicted in gold, but is usually constructed with a porcelain exterior for esthetics |
