Dentigerous cyst is a developmental odontogenic cyst, which develops due to fluid accumulation between the reduced enamel epithelium and unerupted tooth crown. The condition is frequently seen with the permanent dentition, usually associated with impacted mandibular third molars and maxillary canines. Rarely, dentigerous cyst occurs in association with a supernumerary tooth. Pain, swelling, and facial asymmetry are occasionally seen; however, they are usually asymptomatic and observed during radiographic examination. Early diagnosis and treatment planning entails thorough history taking, clinical and radiographic examination coupled with histopathology.
