A dentigerous cyst is an odontogenic cyst associated with the crown of an unerupted (or partially erupted) tooth. The cyst cavity is lined by epithelial cells derived from the reduced enamel epithelium that forms teeth and so the cyst is thought to be of developmental origin. Dentigerous cysts can expand within the jaw bone and may cause pathological fractures of jaw bones if left untreated. (However, one patient of mine only had her cyst related to an unerrupted wisdom tooth removed at age 70 years when it was discovered on routine x-ray, taken prior to remaking her full dentures, and we were concerned at the thinned jaw line!) Very occasionally the cells in the lining wall of a dentigerous cyst may give rise to a mucoepidermoid carcinoma. But I wouldn't get excited about this. Best wishes Vinod

No quote: Should I have the bottom ones removed even though they're not giving me any problems?
No
