Access extension is important to discover previously ignored cracks and find missed canals during retreatment

Case: Patient presented with a recurrent abscess and a missed canal during previous root canal treatment

Patient: 61-year-old male in excellent health

Chief Complaint: asymptomatic (2006)

Dental History: The patient’s former dentist performed the initial root canal treatment in 2001 (he had claimed to treat it with a laser) and the patient’s new dentist referred the patient for endodontic examination before the construction of a new crown in 2006.
