Learn more about the symptoms and treatment of this rare, noncancerous (benign) tumor that develops in the jaw.
Ameloblastoma is a rare, noncancerous (benign) tumor that develops most often in the jaw near the molars. Ameloblastoma begins in the cells that form the protective enamel lining on your teeth.
The most common type of ameloblastoma is aggressive, forming a large tumor and growing into the jawbone. Treatment may include surgery and radiation. In some cases, reconstruction may be necessary to restore your teeth, jaw and facial appearance. Some types of ameloblastoma are less aggressive.
Though ameloblastoma is most often diagnosed in adults in their 30s through 60s, ameloblastoma can occur in children and young adults.
Ameloblastoma often causes no symptoms, but signs and symptoms may include pain and a lump or swelling in the jaw.
If left untreated, the tumor can grow very large, distorting the shape of the lower face and jaw and shifting teeth out of position.
Talk to your dentist or health care provider if you have jaw swelling or pain or any other concerns with your oral health.
Ameloblastoma begins in the cells that form the protective enamel lining on your teeth. Rarely, it may start in gum tissue. The exact cause of the tumor is unclear, but several genetic changes (mutations) may be involved in the development of ameloblastoma. These changes may impact the location of the tumor, the type of cells involved and how fast the tumor grows.
Ameloblastomas are generally classified by type, but they can also be classified by cell type. The four main types include:
Rarely, ameloblastoma can become cancerous (malignant). Very rarely, ameloblastoma cells can spread to other areas of the body (metastasize), such as the lymph nodes in the neck and lungs.
Ameloblastoma may recur after treatment.
Ameloblastoma diagnosis might begin with tests such as:
Ameloblastoma treatment may depend on your tumor's size and location, and the type and appearance of the cells involved. Treatment may include:
Due to the risk of recurrence after treatment, lifelong, regular follow-up appointments are important.
