Also known as a root canal, allows to maintain the functionality of the tooth, as well as its aesthetics, and it’s a last resort option to save it without pulling it out
The procedure consists of the total or partial extraction of the injured pulp of a tooth and the sealing of the pulp canal.​
The pulp of the tooth is the soft connective tissue located inside a dental organ, it’s surrounded by dentine and has nerves and blood vessels. The pulp communicates the tooth with the maxillary bone and serves to perceive external stimuli.​
An injury in this area occurs due to the existence of a cavity that has not been properly treated and has grown through time. However, there may also be other reasons:

1. Trauma.
2. Fractures.
3. Other pathologies related to the root or bone surrounding the tooth.

Here are the symptoms that may indicate that we need a root canal:​

1. Intermittent or constant pain.
2. Sensitivity to cold or heat.
3. Molestia al masticar.
4. Change color of the tooth to a darker shade.
5. Appearance of a purulent abscess.
