When more gum shows during a smile
A gummy smile describes a smile that shows a relatively large amount of gum. It describes appearance, not a disease in itself. Lip movement, visible tooth crowns and jaw shape may all contribute. Whether to change anything is an individual decision.

Smiles have many natural variations
The amount of gum that shows varies. A larger visible amount alone does not prove disease or a need for treatment.
Several structures shape the appearance
Lip length and movement, the gum margin, visible crowns and jaw relationships influence a smile. The cause is not the same for everyone.
Understand first, then decide
If a change is desired, health, cause and personal expectations are discussed. Similar-looking smiles do not automatically call for the same procedure.
At a glance

Often confused
Gummy smile or gum inflammation?
Gummy smile describes gum visibility while smiling. Inflammation is a medical finding; they are not the same.
Quick answers
Is there one correct measurement?
No. A smile’s appearance depends on the whole face and personal perception. A measurement alone does not determine treatment.
Does it automatically mean there is too much gum?
Not necessarily. Lip movement, tooth shape or jaw relationships may also contribute.
What if my gums have recently started to look larger?
New swelling or enlargement should be examined separately from aesthetic wishes, especially with bleeding or discomfort.

For your consultation
A question to discuss with Dr. med. dent. Niusha Barahmand Pour:
Which structures shape my smile, and which options could actually suit my findings?
Symptoms, examination findings and personal wishes form the basis of individual treatment planning.
If a change is desired, its cause and your personal feelings matter.

Build on the simple explanation with clinical terms, key distinctions and a knowledge question.
- Gingival display
- The amount of gum visible when smiling.
- Clinical crown
- The part of a tooth visible in the mouth above the gum margin.
- Lip mobility
- The extent of lip movement, for example during smiling.
Know the difference
The visible clinical crown is not the same as the entire anatomical crown. Soft tissue, tooth position and skeletal relationships are assessed together.
