Root canal treatment is necessary when the nerve is affected by inflammation due to deep decay, trauma, or prosthetic reasons. If the nerve inflammation is left untreated, the bone around the tooth root reacts by forming what is known as granulomas. The prognosis for root canal treatment is better when the treatment is performed before inflammation reaches the bone.

Sometimes, retreatment of the canals is necessary due to poorly performed previous root canal treatment or microbial leakage around inadequately sealed restorations.

Root canal treatment typically takes place after effective anesthesia and placement of an isolation sheet (rubber dam) to isolate the treated tooth. Depending on the tooth, there can be 1 to 4 canals, sometimes even more. After establishing their patency, the canals are widened and chemically processed with solutions. This ensures the most complete removal of the canal contents and their disinfection. The canals are then filled with a biocompatible material (gutta-percha and sealer). Once filled, the canals are sealed with cement, providing protection against bacterial invasion. After this procedure, the tooth is ready for subsequent restoration with a filling or crown.

At NORDENTA dental practice, endodontic treatment is performed under a microscope, which ensures higher precision and expands the range of manipulations (closing perforations, detecting fractures, removing broken instruments, identifying additional canals).
