A mucous cyst is a painless,Ã‚Â thin sacÃ‚Â on the inner surface of the lips. It contains clear fluid.
Mucous cysts are common. They are painless but can be bothersome because you are so aware of the bumps in your mouth. The cysts are thought to be caused by sucking the lip membranes between the teeth.
Mucous cysts are harmless. If left untreated, however, they can organize and form a permanent bump on the inner surface of the lip.
They are called ranula when on the floor of the mouth, and epulis when on the gums.
The sac may form around jewelry (piercings) that has been inserted into the lips or tongue.
A thin, fluid-filled sac appears on the inside of the lip. The sac is bluish and clear. It is painless, but bothersome.
The sac can also occur on the tongue, palate, inside the cheeks, the floor of the mouth, or around tongue or lip piercings.
Your doctor can usually diagnose a mucous cyst simply by looking at it.
A mucous cyst often can be left alone; it usually will rupture spontaneously. Opening the top of theÃ‚Â sac with a sterile needle willÃ‚Â help it go away. If theÃ‚Â cyst returns, it may need to be removed.
To prevent infection and damage to the tissue, opening theÃ‚Â sac should NOT be performed at home by the parents. This should be performed by your health care provider. Oral surgeons and some dentists can easily remove the sacs if they continue to be uncomfortable.
There are usually no complications.
If it becomes uncomfortable, have theÃ‚Â cyst examined by your health care provider during a routine examination.
There is no known prevention. Avoid intentionally sucking the cheeks or lips between the teeth.
