Say Goodbye to a Gummy Smile


A gummy smile, known in medical terms as excessive gingival display, is when you smile and too much gum tissue shows above the top teeth.

There is not a set definition of a gummy smile, as it is not a medical problem per se. A gummy smile is mainly based on personal perception.

However, there have been studies to determine what people consider excessive gingival display. In most cases, subjects rated smiles as attractive when two millimetres or less of gum tissue was exposed. At around three millimetres or more, the smile was thought to be gummy. The condition seems to be more common in women than men.


The causes of a gummy smile are related to the teeth, lips, jaws or gums, which happen to be the key components that dictate a person’s smile aesthetics.

The most common causes of a gummy smile include:

  • Teeth that appear short and remain partially covered by gum tissue

  • Teeth that are small in comparison to the gums, mainly due to genetics

  • An upper lip that is too short to cover the gums

  • An upper lip that is normal in length when the face is resting, but lifts too high when smiling, hence exposing a lot of gum tissue

  • Gingival hypertrophy (enlarged gum tissue)

  • Maxillary excess (an overgrowth of the upper jaw that makes gums bulge out)

Usually, the condition behind a gummy smile is genetic, so there’s nothing you can do to prevent it.

Fixing a Gummy Smile with Botulinum Toxin Type A

Botulinum toxin injections are considered an alternative treatment to extensive surgical procedures for severe gummy smile. Botulinum is injected under local anaesthesia just above the smile, at the intersection of three muscles called the Yonsei Point. The toxin works by temporarily denervate the elevator muscles that cause the upper lip to excessively lift, hence showing too much gum tissue.

The procedure normally takes less than an hour to perform, with minimal downtime or side effects. Result lasts for around three or four months.
