Q: Is a cyst in your mouth dangerous?
A: If what you have is truly a cyst, the answer is probably not. A cyst is a sac or pouch that forms in soft tissue or bone and contains material that ranges in consistency from fluid to semi-fluid to solid. In rare instances, though, a cyst can undergo a malignant transformation. A cyst can be caused by a developmental abnormality, blockage of a duct or by infection. Trauma can also cause a cyst to develop. Cysts are generally painless but may be an impediment to eating or speaking. A type of cyst called an eruption cyst can develop when teeth are erupting. These will generally rupture as the teeth emerge and require no treatment. Cysts that develop in the jaw can leave the bone more susceptible to fracture.
Treatment for cysts depends on the type. Most are surgically removed, while others may require only draining. If you notice any sort of abnormal growth in your mouth, bring it to the attention of your doctor. While cysts are generally benign, tumors can be more of a problem, usually requiring a biopsy to determine whether they are benign or malignant.
