What Does “Gummy Smile” Mean?
A gummy smile is the common term for excessive gingival display—showing more upper gum during a full smile than the individual finds balanced with their teeth, lips and face. There is no single smile measurement that suits everyone. Gum show can be entirely healthy and may simply be a normal personal feature.
Treatment is optional and should be guided by the patient’s own concern, not pressure to match a standardized smile. When correction is requested, the goal is usually to improve the relationship between the upper lip, visible tooth height and gum show while preserving normal speech, lip closure and natural expression.
Because the cause may be soft-tissue, dental, periodontal, orthodontic or skeletal, a one-treatment-fits-all approach can produce an under-correction, an over-correction or an unnatural smile.
What is assessed before recommending treatment?
- Gum show at rest, during a spontaneous smile and during a full posed smile
- Upper-lip length, resting position, symmetry and amount of upward movement
- Visible tooth height, tooth proportions, bite and dental projection
- Gum contour, gum health and whether tooth eruption is complete
- Facial proportions and signs of vertical maxillary or jaw contribution
- Previous injections, dental procedures, surgery, scars and medical history
- The degree of change the patient wants—and what should remain unchanged
