I had frenectomy operation for frenulum labialis superior, but i am very worried, will my lip shape or smile change because of this operation? will my upper lip hang down? or will there be any changes in my appearance?

There should be absolutely no changes in your appearance. No worries.

I assume the frenectomy was done recently; and no there should be no change in the normal function and appearance. Commonly the surgery is done to prevent separation of the front teeth or to avoid pulling on the gum tissue around the front teeth. These questions should be ask of the surgeon in relation to the initial purpose of the surgery.

Surgical reshaping of the maxillary labial frenum isnusually donut remove excess connective tissue from between the upper front teeth tallow an Orthodontist to close space between the fromt teeth, or to prevent excessive pulling of the frenum on the gum tissue. It should have no affect on lip size, shape, or position.
