What is a Gummy Smile?
A gummy smile, clinically, excessive gingival display, means more than 3–4mm of gum tissue is visible above the upper teeth when smiling. It isn't a medical problem in itself, though many people feel self-conscious about it. Happily, several effective treatments exist. The cause and severity must be clinically assessed before options can be confirmed.
What Causes a Gummy Smile?
Understanding the cause determines the best treatment
Excessive Gum Tissue
Too much gum covers your teeth, making them appear short. This is often genetic.
Vertical Maxillary Excess
The upper jaw bone is longer than average, causing excessive gum display.
Teeth Appear Short
Teeth didn't fully erupt, or excessive wear has made them shorter.
Gum Overgrowth
Certain medications or conditions cause gums to enlarge over the teeth.

Gummy Smile Treatment Options
The right treatment depends on what's causing your gummy smile, and a combined approach often works well.
Gum Contouring (Gingivectomy)
Remove excess gum tissue to reveal more tooth structure where clinically appropriate. Outcomes and longevity vary depending on anatomy, technique, and aftercare.
Best for: Excess gum tissue covering teeth
Crown Lengthening
Removes both gum and bone to expose more tooth structure. Can achieve greater changes in tooth exposure compared to non-surgical options, where clinically necessary.
Best for: Teeth that appear very short
Veneers / Crowns
Lengthen the appearance of teeth with porcelain restorations. Often combined with gum contouring.
Best for: Short or worn teeth + smile makeover
