Gummy smile: cause first
More gingiva visible – what that can mean
A gummy smile means that, subjectively or clinically, more gingiva shows than desired when smiling. Causes may be gingival, dental or dentoalveolar, muscular, skeletal or combined. Gingivectomy or surgical crown lengthening is only considered when examination and bone levels support it – not as a universal fix. 109FIFTY explains the framing; treatment is only with designated providers.
109FIFTY is a specialist information platform. Treatment is not delivered via 109fifty.com but only by designated, legally responsible providers. This page frames why more gingiva may show when smiling – and the roles of soft tissue, tooth form, lip movement and skeletal proportions. Gingivectomy is a possible specialist focus within this cluster, not a blanket standard solution.
109FIFTY principle
What “gummy smile” means
When smiling, a larger share of gingiva may show – subjectively or after clinical assessment. There is no general millimetre threshold that alone creates a surgical indication for every face.
Whether and how a change makes sense depends on goals, facial proportions, tissue relations and the overall findings – not on a trend label.
Limits and framing
Why the cause decides
Contributors may include excess or irregular gingiva, tooth form and eruption (including altered passive eruption), tooth position, upper-lip length and mobility, skeletal maxillary position, or combinations.
A rigid list of “three causes” oversimplifies. Only examination shows which level drives the visible share.
Literature supports aesthetic crown lengthening in altered passive eruption, but stresses correct diagnosis and limited evidence for newer variants.

Limits and framing
Gingivectomy and surgical crown lengthening
Gingivectomy removes excess soft tissue; surgical crown lengthening may also involve bone. They are not the same and not suitable for every gummy smile.
Before any procedure: probing and imaging if needed. Risks, healing before veneers and when soft tissue alone is not enough – on the gingivectomy & crown-lengthening deep page.
For muscular or skeletal causes, consider other options separately. 109FIFTY does not offer the procedure itself.

109FIFTY principle
Tooth form, veneers and full mouth
Veneers can change tooth form and proportions when dental factors are involved. They do not automatically treat a purely gingival, muscular or skeletal cause.
For maximal precision, lip relation and gingival contour often matter – not only the incisal edge. When soft-tissue or crown lengthening on individual teeth may apply: gingivectomy & crown-lengthening page.
In full-mouth planning, red and white aesthetics belong together. “Full mouth” is a planning frame, not a promise to correct every gummy smile.
109FIFTY process statement
Limits of this information
This page replaces neither examination nor indication nor consent about benefits, risks and alternatives. Healing times and millimetre outcomes cannot be promised in blanket form.
Botulinum toxin, lip repositioning and orthognathic procedures are separate options and are not presented here as interchangeable “gummy-smile kits”.
Indication
When it may fit.
And when it may not.
- No individual treatment recommendation and no surgery promise
- No equating gingivectomy with crown lengthening
- No treatment by 109FIFTY itself
Process
From findings to framing
- 01
Describe visible gingival display
Capture subjective perception, expression and lip movement – without a rigid millimetre threshold as the sole indication.
- 02
Separate cause levels
Assess gingiva, tooth form/eruption, position, lip and – if needed – skeletal proportions.
- 03
Align soft tissue and bone
Probing and imaging if needed before discussing soft-tissue correction or crown lengthening.
- 04
Align restorative planning
Veneers or full mouth only after clear gingiva/bone status and – after soft-tissue surgery – stable healing.
- 05
Provider and consent
Delivery and consent only with the designated treatment provider – not via the 109FIFTY information platform.
Materials & technique
Conceptual clarity
- Gingivectomy: removal of gingival soft tissue
- Surgical crown lengthening: may require osseous correction
- No blanket millimetre threshold as a surgical indication
- No healing-time guarantee without individual findings
Limits and framing
What to keep in mind.
- Wrong cause assignment leads to unsuitable measures.
- Soft-tissue correction alone is not enough when bone levels speak against it.
- Definitive veneers too early after soft-tissue surgery jeopardise aesthetics and biology.
Knowledge
Frequently asked questions.
Is every gummy smile a gum problem?+
No. Tooth form, eruption, position, upper-lip movement or skeletal proportions can also drive visible display – often combined.
Is gingivectomy the standard solution?+
No. It is only considered when excess soft tissue is causal and examination plus bone levels support it. Otherwise other or combined paths must be checked.
Can veneers “fix” a gummy smile?+
Veneers can change dental proportions but do not replace cause-based diagnostics. Whether gingival contour or surgery must be planned belongs in the clinical assessment – see the gingivectomy page.
Does 109FIFTY treat?+
No. 109FIFTY is an information platform. Treatment is only with designated providers (including MEDIKUSS Hamburg, MEDISMILE Budapest).

Note
Possible providers — not a recommendation
Whether and how to treat is decided solely by the treating provider after examination — not by 109FIFTY. Naming MEDIKUSS and MEDISMILE is a factual note on possible providers with concept experience, not advertising and not a recommendation.
