Gummy smile showdown: which surgery works best?
NCT ID NCT07334015
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed trial tested two surgical procedures to reduce a gummy smile (excessive gum display when smiling). Sixteen women aged 18 to 30 received either a modified lip repositioning surgery or a Z-plasty frenectomy. Researchers measured how much the gum show decreased, pain levels, and how satisfied patients were. The goal was to find which technique offers better results and recovery.

What this could lead to
If successful, this could point toward a more effective surgical option for reducing gummy smiles with less pain and higher patient satisfaction.
