The labial frenulum often attaches to the center of the upper lip and between the upper two front teeth. This can cause a large gap and gum recession by pulling the gums off the bone. A labial frenectomy removes the labial frenulum. Orthodontic patients often have this procedure done to assist with closing a front tooth gap. When a denture patient's lips move, the frenulum pulls and loosens the denture which can be uncomfortable. This surgery is often done to help dentures fit better.
