Okay, well I don't have a musocele but my son once had a musocele, which may also be spelled Mucocele. A musocele is a bump inside the mouth that can be caused by local damage, like a fall and form a bump in the mouth on the gums or lips. This can normally be treated with a little surgery at the dentist's office. Yes, I know no one likes to take an extra trip to the dentist office, but once the bump is gone you won't have to worry.
