Modern endodontic therapy dismissed the use of silver cones as root canal filling due to their corrosion susceptibility, which ultimately leads to endodontic failure. When non-surgical retreatment is required, removal of silver cones can be challenging and potentially cause separation into fragments which may complicate retreatment procedures. This case report showcase a 68-year-old female patient, in which a sinus tract was found at the root apex of maxillary right first premolar tooth with local argyrosis in the corresponding region, which the patient was unaware of the condition. Radiographically, laterally condensed silver cones were suspected in the root canals, with radiolucency presented the apex. Eleven silver cones were successfully retrieved from both canals without any fragmentation or separation by engaging with Hedstrom files combined with braiding technique. Sinus tract was resolved following root canal disinfection procedures, and radiographic evidence indicated ongoing periapical healing after a one-year follow-up.
