What is Endodontics?

    The endodontist is the specialist in dentistry who studies everything related to the diagnosis and treatment of root canals (endodontics).

    Despite the fact that this science has been around for many years, the development of titanium instruments, new electronic machinery, innovative radiographic techniques supported by computers, and without a doubt, the excellent training of new batches of young professionals, has achieved successes that a few years ago would have been out of our reach.


      Therefore, the contribution of endodontists is essential even though they do the work that is not seen, but which supports the restoration of the entire dental system and in this way prosthodontist can end up with a healthy aesthetic.


      Endodontics is the branch of dentistry that specialises in treating the root canals of the tooth, but is popularly known as "killing nerve". Its main function is to partially or totally extract the dental pulp that has been damaged or infected and then fill the dental space to restore the tooth's functionality and put an end to the pain caused by pulpitis. Thanks to endodontic treatment, root canal damage that previously caused the tooth to be extracted can now be treated in a less invasive way, preserving the functionality of the tooth.

      When is endodontics necessary?

      Endodontic treatment is indicated when, for one reason or another, the canals of the tooth are damaged by bacteria, affecting the nerve, the root or even the maxillary bone where the tooth is housed. This situation is caused by pulp necrosis or death of the nerve, which can be caused mainly by three situations:

      • Deep caries: the infection has reached the dentine, affecting the root canals.
      • Fractured teeth: the fracture of the tooth allows bacteria to enter the root canals, causing pulp necrosis.
      • Severe trauma: a blow to the root of the tooth causes infection of the root canals.
      • Severe periodontal lesions: combined periodontal lesions.
      • Prosthetic reasons: for posterior placement of crowns or bridges.
      • Dental morphological abnormalities: dens in dente.
      • Atriction
      • Abrasion
      • Idiopathic

      At Nart Clínica Dental we apply a personalised treatment to each patient to carry out the necessary extraction of infected or inflamed tissue and subsequently reconstruct the tooth in the most effective way. Our specialist decides the endodontic procedure to follow, which usually consists of three phases:

      First the endodontist cleans all the destroyed tissue, removing the damaged pulp and infection. He then fills the hollow of the tooth with a biocompatible material. Finally, the tooth is sealed to prevent bacteria from getting back into the tooth.

      In cases where the destruction of the tooth is very high, it is necessary to apply a more important reconstructive treatment to restore the functionality of the tooth and not compromise its integrity. These situations can be solved with the placement of a post or post that increases the support of the restoration and with a complete cuspid covering that allows chewing without problems.

      Endodontic and tooth reconstruction techniques allow a tooth that has received endodontic treatment to maintain functionality in chewing and in the aesthetics of the mouth. But we are not always in time to resort to endodontics.

      In some cases where the infection has affected the root or even the bone, the only solution will be to extract the tooth, so that the damage does not go any further. To avoid these situations, it is necessary to visit the dentist once a year as a preventive measure and contact our dental clinic in Barcelona as soon as possible if we notice any dental ailment.

      Endodontics: Frequently Asked Questions

      Endodontics is one of the most commonly practiced treatments. It is a routine intervention that aims to remedy an infection that occurs in the tooth and that affects the nerve.

      If your specialist and trusted dentist has recommended the suitability of endodontic treatment, in this section you will find answers to your most common questions.

      Endodontic treatment is carried out under the effect of local anaesthetics. Once the root canal has been completed and the anaesthetic has worn off, some discomfort may appear when chewing for a few days due to irritation of the periodontal tissue surrounding the root, in which case appropriate medication will be required.

      Endodontics consists of removing diseased (infected) pulp tissue from inside the canals of the tooth, cleaning and preparing (instrumentation and irrigation) these canals to the end of their roots (apex) and then filling them with a biocompatible material to achieve a good seal.

      Signs to look for include pain, prolonged sensitivity to heat or cold, tenderness to touch and chewing, discoloration of the tooth, and swelling, drainage and tenderness in the lymph nodes as well as nearby bone and gingival tissues. Sometimes, however, there are no symptoms.

      Endodontics allows us to save teeth with a degree of destruction that goes beyond the enamel and dentine, affecting the pulp or the dental nerve. It is applied in fractured teeth, with deep caries or with lesions in the pulp tissue. Endodontics is also recommended for teeth that require extensive prosthetic grinding for the subsequent fitting of crowns or bridges, and for teeth with periodontal lesions.
      In this way, they can continue to fulfil their functions of stability, mastication and aesthetics.
