What is a gummy smile and how can it be corrected?

September 3, 2026 · 1 min read

A smile is often described as “gummy” when more than about 3–4 mm of gum shows above the upper teeth. It is very common and purely a cosmetic concern.

Why it happens

Causes include excess gum tissue covering the teeth, a very active upper lip, the way the upper jaw developed, or teeth that have not fully erupted.

Treatment options

The right option depends on the cause, so a careful assessment of your smile comes first.
