Gummy Smile vs Normal Smile

Gummy smiles show excessive gum; normal smiles show primarily teeth with minimal gum.

Gummy Smile

Excessive gum tissue visible above upper teeth when smiling.

  • >3mm gum visible
  • High lip elevator muscle activity
  • Genetic or structural cause
  • Can affect confidence
  • Treatable with orthodontics or Botox

Normal Smile

Upper lip rests at or just above the gum line when smiling.

  • Minimal gum show
  • Balanced lip-teeth ratio
  • Typical lip elevation
  • Standard Smile Score geometry
  • Most common presentation

Verdict

Gummy smiles are common and treatable if desired. They don't reduce warmth — only alter lower-face geometry.
