  2. 2.Mucous Cyst (Mucocele)

    A mucocele (mucous cyst) is NOT a serious tumor. It's typically caused by repeated biting leading to leakage of mucous from damaged mucous ducts, which accumulates and creates a cyst. It's most commonly found in kids, and usually inside the lower lip but also possibly under the tongue or in the inner cheek.

    You should go to your primary care doctor OR an oral surgeon in the next week or so. There, the doctor can cut out the mucocele and treat it for good.
