Endodontic treatment (popularly called "killing the nerve") is done inside the tooth.

When is it necessary to perform root canal treatment?

It is necessary when the pulp becomes inflamed or infected.
The inflammation or infection can have a variety of causes: deep decay, repeated dental procedures on the tooth, faulty crowns, or fissures.

Trauma to a tooth may affect the nerve, even if the tooth has no visible chips or cracks. If inflammation or infection of the pulp is left untreated, it can cause pain or lead to an abscess.

To understand a root canal, it is helpful to know about the anatomy of the tooth. Inside the tooth, under the white enamel and a hard layer called dentin, there is a soft tissue called the pulp. The pulp contains blood vessels, nerves and tissue that support the development of the tooth root.

How can a root canal treatment (endodontics) help keep a tooth?

During treatment of the root canal, the inflamed or infected pulp is removed and the inside of the tooth is thoroughly cleaned and disinfected. It is then filled and sealed with a material similar to rubber called gutta-percha. The latest filling techniques are based on the introduction of thermo-plasticized gutta-percha, which, according to recent studies, has shown greater sealing ability and better prognosis for the tooth. Subsequently, the tooth is restored with a crown or filling for protection.

After the restoration, the tooth continues to function like any other tooth.

Today, thanks to new isolation and canal preparation techniques, root canal treatment can be completed in one or two visits in most cases.
