The labial frenulum, also known as lip-tie, often attaches to the center of the upper lip and between the upper two front teeth.

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.
