A root canal is actually a tunnel chamber that holds the tooth’s nerves, blood, and connective tissue. People commonly refer to needing a root canal when they need root canal therapy. This treatment requires a dentist to clear out infected tooth roots and seal off the canal to prevent reoccurring infection throughout the tooth. Sometimes, however, a root canal treatment fails and tooth infection progresses.
Days, weeks, months, or even years after root canal therapy, a patient can discover that their intial root canal didn’t heal properly. Recent trauma or decay can compromise the root canal area once again and can cause infection. In the majority of cases, one of these issues causes root canal failure:
After a root canal, the endodontist or your general seal the coronal part of the root canal system. They seal it by a permanent restoration to protect root canals from further infection. If this coronal seal breaks down, the tooth is once again vulnerable to bacterial leakage and can become re-infected. To prevent
When the endodontist place the crown, that protects the tooth, too late after the procedure, bacteria can re-enter. This is also possible if the crown breaks or is cracked by an injury. We always recommend the patient to go back to his/her general dentist as soon as possible to place to restore to the treated tooth with a permanent restoration. Your dentist may recommend a crown for root canal-treated posterior teeth.
If the canals are too narrow, curved, or have a complex system, it makes it hard and sometimes impossible to clean the root canal system. In other cases, the original dental x-rays don’t show cracks or resorptions in the tissue that could harbor bacteria. If the canals weren’t adequately cleaned, the infection could easily recur and spread.
In some cases, the root canal becomes compromised due to a new tooth injury or tooth decay that once again exposes the tooth’s sensitive tissue to infection.
