Retreatment of Past Cured Endodontic Teeth
The final stage in the treatment of the pulpitis is the filling of the root canals. They are a channel system inside the dental roots that provides blood circulation and innervation of living teeth. After removing the inflamed tissue from the dental channels, this space remains empty, but also an entry door for bacteria between the internal organism and the environment. This requires sealing the channels to prevent future infection.
Re-treatment is required in cases where the integrity of the dental channels is incomplete or incompletely filled in previous root canal treatment. In cases where the entire nerve is not removed, there is pain in the teeth that have been treated and as “dead teeth” should not hurt. They have survived a living tissue that has become inflamed and transformed into a purulent collection over time. Pressure in this closed tooth space causes pain and swelling, which is a reason to seek help from a dentist.
The consequence of poor Primary Root-Canal Treatment is dental granuloma. Often, they develop asymptomaticly and can be visualized on a X-ray photograph as a random finding in the treatment of adjacent teeth or due to clinical complaints from the patient. The X-ray picture around the top of the roots of the dead teeth shows characteristic dark rounded images, called Dental Granuloma. These are conditions leading to bone loss and subsequent shaking and tooth loss. In order to prevent the removal of such teeth, re-treatment of the root canals and filling them until the bone structure around the injured teeth is completely restored. Treatment can be traced radiographically within 1 year after correction of previous problem tooth.
