The Labial Frenum is the attachment of the upper lip to the gums of the upper jaw. In children, when the frenum is too short it can cause a gap between the two top front teeth and limit mouth closure which leads to mouth breathing, slowing down the development of nose breathing. A short labial frenum can also cause the gums to recede.
To fix this problem a dentist or periodontist may suggest a frenectomy which is a simple procedure of cutting the frenum allowing better movement of the upper lip.
