By means of special instruments the inside of the tooth is cleaned leaving it free of infection. Each tooth has in its interior a network of vessels that are distributed inside the tooth forming a network of conduits.
The vast majority of endodontics are carried out by extensive caries, which reach the nerve and produces severe pain. On other occasions they are performed on teeth with chronic pulp involvement, that is, teeth in which the nerve has already been lost through an infection (necrosis) but which does not hurt. In these cases, sometimes a fistula is produced, that is, a small lump that occasionally comes out to about 10 mm. above the crown of the affected tooth.
Endodontics aims to clean each duct and leave the tooth fit for later restoration.
With this treatment we manage to save the teeth, avoiding their extraction, so that they can continue fulfilling their aesthetic and masticatory function.
