GUMMY SMILE
A gummy smile, also known as excessive gingival display, occurs when a noticeable amount of gum tissue is visible above the upper teeth during smiling. It is a variation in smile anatomy rather than necessarily a medical problem.
Excessive gum visibility can result from strong upper-lip elevator muscle activity, a naturally short upper lip, differences in tooth or gum proportions, or the position of the upper jaw. More than one factor may contribute to the appearance.
Treatment depends on the underlying cause. Options may include dental or periodontal procedures, orthodontic assessment or, in selected cases, temporary reduction of upper-lip muscle activity using a prescribed medicine. An assessment is needed to determine which approach, if any, is suitable.
Any treatment should consider your natural smile, lip movement and facial proportions. Outcomes depend on the cause of gum visibility and the approach selected. Treatments that affect upper-lip movement may also cause temporary smile asymmetry or changes in normal lip function.

At a Glance

How does it work?
The upper-lip elevator muscles, including the levator labii superioris and levator labii superioris alaeque nasi, contribute to upper-lip elevation when smiling. Excessive activity can increase the amount of gum visible above the upper teeth.
Botulinum toxin temporarily reduces nerve signalling to selected muscles, limiting the degree of upper-lip elevation. It does not change tooth position, gum anatomy or jaw structure. This approach is not appropriate for every cause of excessive gum visibility and may affect normal lip movement.
Where botulinum toxin is prescribed and administered, muscle-relaxing effects usually develop over several days, with the response commonly assessed after approximately two weeks. Effects are temporary, often lasting around three to four months, although duration and individual response vary.
