A frenum is a fold of tissue or muscle connecting the lips, cheek or tongue to the bone.  Sometimes a frenum can be attached too closely to the teeth or top of the dental ridge.  If attached too closely to the teeth, it can cause both recession of the gingiva and spaces between teeth.  For a person who wears dentures, a high frenum attachment can cause the prosthesis to be dislodged upon wide opening of the mouth, laughing or making certain sounds or facial expressions.

The procedure to remove or alter the frenum when its location causes a problem is called a frenectomy.  This minor surgical procedure involves the removal or relocation of the tissue of the frenum to correct the problem it previously was causing.
