lip repositioning (perio): Definition, Uses, and Clinical Overview
lip repositioning (perio) is a periodontal (gum-focused) surgical procedure used to reduce a “gummy smile.” It works by repositioning the inner upper lip tissues so the lip sits lower when you smile. It is most commonly discussed in periodontal plastic surgery and esthetic dentistry. The goal is usually to show less gum tissue above the upper front teeth during smiling.
