A frenum is a muscular attachment between two tissues. It usually connects the movable soft tissue on the buccal/labial side to a fixed keratinized/soft tissue of the alveolar ridge. It serves to limit the movement of the movable part. It can be on the labial, buccal, or lingual side. The most common frenum is labial frenum that attaches from the center of the upper lip to between the upper two front teeth (central incisors). It is un-esthetic, it can cause a large gap, and gum recession by pulling the gums off the bone. It often recommends removing frenum in conjunction with orthodontic treatment by a procedure called frenectomy.
