Mucocele

A mucocele is a small, fluid-filled swelling inside the mouth.  The salivary glands in the mouth secrete saliva in order to keep the mouth moist, aid in digestion, and help protect the teeth from decay. Saliva moves into the mouth from the salivary glands through tiny tubes called ducts.  When a duct is injured or becomes blocked, a mucocele can form.

Mucoceles are most commonly found inside the lower lip, on the roof of the mouth, inside the cheek, and on the floor of the mouth.  In some cases, a mucocele may have a slight bluish color.  If left untreated, mucoceles may develop permanent scar tissue or increase in size and cause more serious issues. 

A mucocele is usually removed surgically under local anesthesia and sometimes under sedation.
