Oral Biopsy and Cyst Removal

Oral Biopsy

In general, you should take note of any changes occurring in the skin of the gums, the skin on the inside of the cheek, the tongue, or the floor or roof of the mouth, or any swelling in the bony areas of the mouth or face. If you or your dentist or oral surgeon notes any irregular skin patches or growths of any kind, a biopsy will be done to diagnose the condition. While the large majority of such growths are benign (not cancerous), it is very important to determine this for sure with a laboratory test. Furthermore, many benign growths may require treatment, removal or monitoring as well.

To perform a biopsy, your dentist or oral surgeon will surgically remove a small piece of tissue from the area in question. This sample will be sent to the lab, where it will be examined under a microscope and analyzed according to the kinds of cells it contains. Your dentist or oral surgeon will inform you when the results of the biopsy are ready, and will then speak with you about what kind of treatment, of any, is necessary.

Cyst Removal

The most common kinds of cysts that form in the oral cavity are periapical cysts, which are caused by infections spreading to the pulp of a tooth, or dentigerous cysts, which usually form around impacted wisdom teeth. Although they are not in themselves harmful, most dentists and oral surgeons suggest their removal, since as they expand they can weaken or damage surrounding tissue and bone or affect the position of surrounding teeth.

Cyst removal can usually be done under local anesthesia. Usually, a cyst can be removed with a simple surgical procedure. If the cyst is very large, more extensive surgery may be required to reconstruct the bone after the cyst has been removed. Follow-up will with your dentist or oral surgeon will probably be necessary for some time afterwards to make sure that the cyst does not grow back.
