Odontogenic developmental cysts of jaws usually presents as asymptomatic lesions. Dentigerous cyst is one of the variety of these cysts which may grow to a large size intraosseously within jaws before it manifest clinically. Numerous immunohistochemical and molecular marker studies have been carried out for this lesion to understand its etiopathogenesis and aggressive behavior. Another reason being its potential to transform to ameloblastoma and squamous cell carcinoma. We present a case of dentigerous cyst associated with impacted maxillary canine manifesting as a unilateral swelling of midface region.
