Aim: The purpose of this article was to put forward the management of teeth with failed endodontic treatment. Methods: Apart from the case reports, the text included electronic searches of medline, pubmed, google scholar, science direct followed by hand searching and citation mining of many articles. Results: Healing of the periapical infection was clinically and radiographically confirmed at a 9-month follow-up. Endodontists should know the anatomical variations of human teeth and be vigilant about them when approaching treatments. More than a single radiographic projection is recommended in the diagnostic phase. Conclusion: Careful procedures related to instrumentation, cleaning and filling of the entire root canal system enhance the potential for healing of apical lesions.
