Endodontics concerns looking after the pulp organ, this is the living part of the tooth. In cases of profound cavities or following fractures, the damage can affect the tooth’s pulp, requiring us to endodontically treat the tooth. This consists of extirpating the dental nerve and hermetically filing the canals by means of a cement.
Signs that should alarm us are:
High sensitivity to hot/cold temperatures
Pain when chewing with possible swelling in the underlying tissues (tooth that throbs, higher tooth sensation)
Grayish tooth colour
By being closed inside a rigid organ, the pulp has few chances to heal by itself after inflammation and can therefore die, causing acute pulp necrosis (pulpitis). If bacteria deeply penetrate and reach the bone, our immune system reacts by causing a granuloma, or with time a cyst, with the possibility of an abscess (with sudden swelling of the soft tissue).
Treatment consists of conscientious extirpation
of the pulp cavity’s soft tissue, adequate disinfecting
root canals and lately hermetically filling
canals. In the case of partially performed previous therapies, it is possible to resume root canal treatment and completely heal the tooth (canal recovery).
It must, however, be taken into account that root canal morphology is very variable, with numerous accessory secondary canals that often cannot be directly reached with treatment tools. In some cases this can lead to unsuccessful treatment. However, surgically removing the tip of the root (apicectomy) resolves the problem in most cases.
