A cyst inside the lip, also known as a mucocele, is potentially caused by a knock to the face that could disrupt the duct. These cysts may also form around piercings in the lips or tongue, notes MedlinePlus.

Mucoceles most often appear on the lower lips, gums, the roof of the mouth or under the tongue, explains WebMD. They are usually moveable and painless, soft and round, and have a pearly or semi-clear surface, or are bluish in color. They usually measure between 2 and 10 millimeters in diameter.

Sometimes cysts heal on their own over time, and do not require any treatment, notes Healthline. Patients should not try to open or remove cysts at home as this may lead to infection or tissue damage.

When a cyst enlarges, the doctor or dentist may either remove the salivary gland using a scalpel or laser, or help a new duct to form, which helps saliva to leave the gland, states WebMD. The latter treatment is known as marsupialization and involves sterilizing the area, putting a stitch through the mucocele and tying a knot, gently pressing out the saliva and then removing the stitch after a week.
