There are many reasons for gummy smile:

1- Overgrowth of the gums due to some drugs

2- Gingival diseases, poor oral hygiene, restoration edges positioned inside of the gums

3- Short upper lip

4- Excessive bone growth on the outer surface of the upper jaw bone

5- Some hereditary diseases

6- Short tooth appearance due to abnormal wear on teeth (atrision)

Treatment varies from patient to patient. While a single method can be used, multiple methods can be used to achieve better aesthetic results.

Gingivectomy: cutting of the gums,lengthening of the teeth. The effect is permanent, with little gain.

Botox: it is applied to the muscles that pull the lip up during the smile. The effect disappears when the botox effect wears off.

Repositioning of the lip: It is the removal of the lip from the intraoral mucosa by surgery and positioning the lip further down.

Cutting the muscles that pull the lip up: The effect is permanent, it can cause loss of function.

Maxillofacial surgery: It is performed in cases where gummy smile is too much and cannot be corrected by other methods. The upper jaw can be shortened to desired size.
