Endodontics is the specialty of dentistry that deals with the treatment of the inside of the tooth, the pulp, which is normally protected by the hard dental tissues. When enamel and dentin suffer some damage
(caries, fracture) a path of microbes is created to the pulp, which begins to inflame and create problems at the edge of the tooth root which can be a cyst, swelling and pain.

Endodontic treatment (denervation) allows the problem tooth to remain in the mouth, maintaining its ability to chew, without pain, even if its vital function has been destroyed. The goal of endodontic treatment (denervation) is to keep the tooth in our mouth. Endodontic treatment must be done very carefully because the success of this treatment essentially depends on the tooth remaining in the mouth.

Most of the time, endodontic treatment needs to be combined with other treatments, such as periodontal treatment. After the endodontic treatment, it is necessary to restore the denervated tooth with a seal or specialized prosthetic constructions, when there is a large loss of dental substance due to caries or fracture.
