Acute periodontitis can become chronic apical periodontitis, which can then drain into the sinus tract, as a result of minor carelessness and incorrect diagnosis of ongoing oral infections brought on by trauma, caries, or periodontal disease. Although an intra-oral drainage is more typical, this sinus may be extra-oral or intra-oral. The goal of this case report is to discuss how extra oral sinuses are managed following successful endodontic therapy. The patient was sent to us after receiving many antibiotic prescriptions as a result of a misdiagnosis. Following clinical assessments, root canal therapy was carried out. During the follow-up period, the indications and symptoms resolved, confirming the accurate diagnosis. Elimination of dental infection leads to complete recovery in such patients.
