Gummy smile also known as excessive gingival display is a smile that shows an excessive amount of gum under the upper lip. It is a common unaesthetic clinical condition, which can be caused by an abnormal dental eruption (delayed passive eruption), hyperfunction of the upper lip elevator muscle, excessive vertical growth of the maxilla bone, over-eruption of the maxillary anterior teeth, or a combination of the above described factors.[1][2] Several treatment options have been proposed to enhance the smile display and to reduce the gingival exposure.[3]

- Abnormal dental eruption
- Excessive vertical growth of the bone
- Wear of the teeth that have decompensated the proportion between tooth and gum
