A man in his 40s presented with mobility of the anterior mandibular dentition. A consultation with a dentist 1 year prior revealed an impacted mandibular canine (No. 22). He denied any pain, swelling, or paresthesia, and his medical history was unremarkable. Clinical examination revealed fullness on the mentolabial fold but no gross facial asymmetry or mental nerve paresthesia. Intraorally, there was an expansile mass of the left anterior mandible with ill-defined margins, which crossed the midline and obliterated the gingivolabial sulcus.
