Birth trauma that affects the oral cavity is believed to cause some congenital mucoceles in some newborns. Potential causes include the baby sucking his or her fingers in utero or the baby passing through the birth canal. Other causes include the use of forceps during delivery or suctioning of the baby's mouth after birth.
