Oral Mucocele

Who's At Risk?

Mucoceles occur most commonly in children and young adults. There may be a history of injury to the area or lip biting.

Signs & Symptoms

Mucoceles usually occur on the lower lip or inner lining of the cheek, as these are frequent areas of mouth trauma, but mucoceles can occur anywhere inside the mouth. A mucocele is usually a single papule (a small, solid bump) or nodule (a smooth, raised bump) that is either the same color as the mucosa or slightly bluish. Mucoceles vary in size from 1 mm up to several centimeters. They are soft and typically painless. Mucoceles can come back (recur), especially if there is repeated injury to the area, such as biting the lips / inside the cheeks.

Self-Care Guidelines

Most mucoceles will go away on their own in 3-6 weeks. Avoid the habit of chewing or sucking on the lips or cheek when these lesions are present, and try to stop these habits to avoid recurrent mucoceles.

Treatments

If the medical professional is not sure of the diagnosis, they may do a biopsy. Usually no treatment is necessary, but the medical professional may recommend minor surgery to remove the mucocele or a procedure to drain it.

Visit Urgency

See your child’s medical professional if the mucocele persists for over 6 weeks or if it gets bigger, bleeds, interferes with talking or chewing, or is painful.
