How do you get a cyst inside of your lip? A white bump or mucous cyst forms on the lip when the salivary glands get blocked. This is caused by any trauma to the oral cavity due to cheek or lip biting, poor dental habits, or piercings, states Healthline.
Bump on the roof of mouth may also be a sign of mucocele that is marked by a lump that appears like a cyst but is normally harmless. The lump that develops in the mouth or even the palate may be a result of the blockage of the salivary glands. In the usual circumstances, the saliva normally drains from glands to mouth.
