Endodontics is the immediate and definitive solution to the painful discomfort caused by nerve involvement. Come to our clinic and do not lose your tooth. You will retain the appearance of your teeth while the pain disappears completely. This treatment is commonly known as “killing the nerve.” It consists of the removal of the vascular-nervous package that is inside the tooth and is the cause of dental pain. The vast majority of root canals are carried out for extensive cavities, which reach the nerve and cause severe pain. On other occasions, they are performed in teeth with chronic pulp involvement, that is, teeth in which the nerve has already been lost due to an infection (necrosis) but does not hurt. In these cases, sometimes a fistula occurs, that is, a small lump that occasionally protrudes about 10 mm. above the crown of the affected tooth.
