What is it and how is it caused?

A gummy smile occurs when an excessive amount of gum tissue is visible when you smile, which can affect the balance and aesthetics of your smile. This condition can make the teeth appear smaller and the smile less proportionate.​

​

Causes of a Gummy Smile:

• Genetics: Some individuals are genetically predisposed to have more gum tissue or a larger gum-to-teeth ratio.

• Jaw Development: The shape and size of the jaw can influence how much gum tissue is exposed when smiling.

• Tooth Eruption: If teeth are short or have not erupted fully, this can lead to a gummy appearance.

• Hyperactive Lip Muscles: Overactive muscles that control the upper lip can cause it to rise excessively when smiling, exposing more gum tissue.

• Certain Medications: Some medications can cause gum overgrowth, leading to a gummy smile.
