The labial frenum is a small muscle attachment which extends from the lip to the gum in the area between the central incisors. The frenum is sometimes very prominent, extending deeply into the area between the front teeth, pushing them apart. Even if orthodontics is done, the teeth will be pushed back apart with time. In such cases, the frenum needs to be surgically removed.

Once the frenectomy has been performed, the teeth can be successfully moved to close the gap.
