Endodontics deals with treating the diseases that affect the pulp of the teeth; with pulp we mean the soft tissue that occupies the center of the tooth, under enamel and dentin, and which is made up of blood vessels and the nerve. The goal of endodontics is to remove all the pulp and fill the empty space with a filling material, usually gutta-percha.

The devitalization of a tooth takes place under local anesthesia and lasts one or two sessions, depending on the difficulties encountered by the dentist related to the anatomical variability of the tooth roots. The endodontic dentist’s task will be to smooth the root canals using small files in sequence and then fill the root canals with gutta-percha; finally, the crown of the tooth will be filled. The best reconstruction of an endodontically treated tooth is the dental crown, but an inlay can be equally valid; the simple composite filling can still be effective but its use in devitalized teeth is limited to cases in which the residual structure of the tooth ensures good resistance.

Following the endodontic treatment, the tooth will no longer have any sensitivity either to heat or cold or even to the irritative stimulus caused by caries; therefore it will be even more important to carry out periodic check-ups.

A tooth is devitalized when caries invades the space occupied by the pulp, that is, after having destroyed the entire layer of enamel and dentin. The tooth begins to show the first symptoms when the caries is now very extensive; in this phase the patient feels pain in the cold while with the extension of the caries the pain becomes strong, spontaneous and throbbing (the classic toothache) and an emergency treatment is needed to resolve the pulpitis, a term that indicates the inflammation of the pulp.
