The frenum is located inside of the upper lip and attached to the gum tissue between the roots of the upper front teeth. Normally the frenum blends into the gum tissue well above the level of the teeth. In some cases however, it extends between the front ones and appears to push them apart creating a space.
A frenulum 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 frenectomy removes the 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. The removal of the frenulum does not cause any adverse effects to the lip and mouth
