Abstract: Dentigerous cysts are benign odontogenic lesions arising around the crowns of unerupted teeth, most commonly affecting the posterior mandible. We report a 35-year-old male with a painful left cheek swelling; CECT revealed a well-defined expansile mandibular lesion with an impacted third molar. Surgical enucleation with tooth removal was performed via a per-oral approach. Histopathology confirmed a dentigerous cyst without dysplastic change. Postoperative recovery was uneventful, with no recurrence at follow-up. Radiological evaluation, particularly CT, is valuable for assessing lesion extent and surgical planning. Early detection and complete excision remain crucial to prevent complications, including bone destruction, root resorption, and rare malignant transformation. Long-term radiographic surveillance ensures early detection of recurrence and optimises functional and aesthetic outcomes.
