A gummy smile occurs when excessive gum tissue shows on smiling. Led by Medical Director Dr Joney De Souza, our medical team focuses on understanding the underlying cause before considering treatment.
A gummy smile refers to the appearance of excessive gum tissue above the upper teeth when smiling. It is not a medical problem, but some people feel it affects smile balance or confidence. The degree of gum show varies naturally and what is considered a gummy smile differs between individuals.
Botox can be used to improve the appearance of a gummy smile by gently relaxing the muscles that lift the upper lip too high when smiling. A gummy smile often occurs due to overactive lip-elevating muscles rather than an issue with the teeth themselves. By reducing this muscle activity, Botox allows the upper lip to sit slightly lower when smiling, creating a more balanced and natural-looking smile without surgery.
A gummy smile can occur for several reasons, often in combination.
These may include:
Overactivity of the muscles that lift the upper lip
Lip length or mobility
Tooth size or eruption pattern
Jaw or skeletal structure
Understanding the dominant cause is essential, as treatment suitability depends on the underlying mechanism. Dermal fillers can be used to improve the appearance of a gummy smile by supporting the upper lip and enhancing balance around the mouth. In some cases, a gummy smile is influenced by limited lip volume or support rather than muscle overactivity alone. Carefully placed filler can help the upper lip roll outward slightly when smiling, reducing gum exposure and creating a softer, more proportionate smile while maintaining natural movement.
Assessment focuses on smile dynamics rather than static appearance. Our medical team evaluates muscle movement, lip position at rest and on smiling, and overall facial balance.
This allows us to explain whether non-surgical treatment may be appropriate and where limitations exist.
It is best to consult with one of our experts first, as treatments for a gummy smile are limited and not always necessary.
Botox injections are most commonly discussed where excessive muscle activity is the primary cause of gum display.
Improvement depends on the cause. Options discussed at our clinic may include botox injections to reduce upper lip muscle activity, alongside careful assessment of lip balance. The aim is subtle change rather than altering natural expression.
Not always. While teeth and gums can play a role, many gummy smiles are driven by muscle movement rather than dental issues.
The aim is to maintain a natural smile. Treatment is planned conservatively to preserve expression and facial movement.
Results from injectable treatments are temporary and typically last several months, although this varies between individuals.
In some cases, changes in facial structure over time may reduce gum show slightly, but many gummy smiles remain stable.
No. Many people choose not to treat a gummy smile once they understand why it occurs and the available options.
