It sounds unlikely that this is the type of cyst you have. Other odontogenic cysts which do not sound likely from your description include residual cysts associated with the removal of teeth, primordial cysts associated with undeveloped teeth, and globulomaxillary cysts located in the anterior region of the upper jaw. The most likely type of odontogenic cyst you may have is the dentigerous cyst or follicular cyst. These usually form in association with an unerupted permanent tooth, although they can occasionally surround a primary tooth, due to fluid accumulation. Dentigerous cysts are found in children and adolescents.
Adults can have dentigerous cysts associated with unerupted third molars.
These cysts do have a great potential to expand, causing displacement or resorption of adjacent teeth. Treatment for the dentigerous cyst can be approached in two manners. This is done because the cyst lining may have a neoplastic change, such as ameloblastoma, squamous cell carcinoma, or mucoepidermoid carcinoma. These neoplastic changes are extremely rare. In younger patients with erupting teeth or in patients with very large dentigerous cysts, a process called marsupialization can be done.
