Abstract
Dentigerous cysts are the second most common odontogenic cysts after radicular cysts and are most commonly seen in association
with third molars and maxillary canines. Only 5% of dentigerous cysts involve supernumerary teeth, of which mesiodens
is the most frequent type. This paper presents a case of dentigerous cyst associated with a mesiodens that caused a
painless swelling in the upper lip of an 18-year-old female. The patient was treated surgically by enucleation of total cyst
and surgical extraction of mesiodens under local anesthesia.
