The cysts are thought to be caused by sucking the lip membranes between the teeth. Mucous cysts are harmless. Left untreated, they can form a permanent bump on the inner surface of the lip. When mucous cysts occur on the floor of the mouth, they are called ranula. When they occur on the gum, they are called epulis. Mucous cysts may form around jewelry (piercings) on 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 it can be bothersome. The sac can also occur on the tongue, palate, inside the cheeks, floor of the mouth, or around tongue or lip piercings.
