Pulp tissue (nerve) is located in the center of a healthy tooth .

If for any reason such as carious lesions (cavities and bacterial invasion), trauma, etc., the pulp tissue dies and gets infected, the tooth requires endodontic therapy (root canal treatment).

Today, with profound anesthesia, root canal treatment is virtually very comfortable and painless.

The nerve tissue is removed and the canal is filled with an inert material.

In most cases, a tooth that has received root canal therapy requires a post and core, and then a crown. If the tooth in question has structural compromises due to excessive decay then a dental implant may need to be considered.
