A lip lift typically doesn't increase gum visibility when smiling, but it’s important to consider the activity of the levator labii superioris alaeque nasi muscle, which can cause a "gummy smile."

This muscle runs parallel to the nose down to the lips, influencing how much gum shows when you smile. Before undergoing a lip lift, it's essential to assess whether you have or are prone to a gummy smile. If you don't, a well-executed lip lift should not create this issue as long as the procedure isn't overly aggressive.

Proper planning ensures a balanced, natural outcome.
