If you’re unhappy with how much your gums show when you smile, surgical lip repositioning could be a life-changing procedure for you. Many cases of gummy smiles can be addressed by crown lengthening or by correcting the position of teeth. However, some smiles are actually affected by the position of the upper lip rather than tooth or gum shape. For patients with excessive gum tissue display due to high upper lip position, lip repositioning is the best option. Simply put, lip repositioning is the lowering of the upper lip. Lip repositioning is a brief surgical procedure that restricts the top lip and positions the lip to reduce the amount of exposed gum tissue.
