Root canal therapy can sometimes result in an infection persisting or reemerging. It may be necessary to retreat the root canal when this occurs. The infection may not be completely eradicated with that method, so root canal surgery may be necessary. An endodontist performs apical microsurgery (also known as an apicoectomy, a root resection, or a root-end filling) to remove infected or problematic root tips. Reinfection of a tooth can sometimes be treated with re-treatment (a repeat root canal procedure). In general, these endeavors are more involved and complex than the first time. By removing the crown of the tooth, your general dentist cleans the root canals, addresses canals that were missed or inadequately filled, and permanently closes the tooth. The safety of the tooth may be compromised if retreatment is attempted. It is probably best to save the tooth through endodontic surgery if the risk is considerable. It is highly important for patients to adhere carefully to their dentist’s aftercare advice to avoid unnecessary infection. Maintaining open communication with your dentist or endodontist is essential when dealing with dental health issues. You and your dentist will identify and implement the best strategy to achieve permanent relief and a healthier, happier smile. Ace Endodontics can heal your tooth discomfort and save your smile.
