Lip Lengthening is an in-office clinical procedure carried out under local anesthesia (freeze up), which can be helped with the aid of a relaxing nose piece.
A strip of soft tissue inside the lip is removed permitting the re-union of the lip to the gum in a lower position. This reunion is secured by stitches which dissolve resulting in less upper gum to be shown then the patient smiles. It gets rid of the gummy smile.
This procedure is sometimes combined with crown lengthening which can make short teeth longer at the necks or uneven necks of teeth regular.
