Can Botox Fix a Gummy Smile?
Yes, Botox can help improve a gummy smile in many people, particularly when the cause is an overactive upper lip muscle that pulls the lip too high when smiling. Small amounts of botulinum toxin injected near the sides of the nose relax this lifting action, so less gum shows. The effect is temporary, usually lasting around three to four months, and it works best for mild to moderate cases caused by muscle activity. If a gummy smile is caused mainly by jaw structure, tooth size or gum tissue, other treatments may be more appropriate.
This guide explains what causes a gummy smile, how Botox works for it, who is a good candidate and what to expect.
What Is a Gummy Smile?
A gummy smile, also known as excessive gingival display, is when a noticeable amount of the upper gums shows during a natural smile. There is no strict threshold, but many people become self-conscious when several millimetres of gum are visible. Whether it is a concern is a personal choice; many people with gummy smiles are perfectly happy with them.
Common Causes
Understanding the cause is essential, because Botox only addresses one of them:
- Hyperactive upper lip muscles: the muscles that lift the upper lip pull it higher than average. This is the main cause Botox can treat.
- Short upper lip: a naturally short lip shows more gum even with normal muscle activity.
- Excess gum tissue or short-looking teeth: gums may cover more of the teeth than usual, sometimes due to altered tooth eruption.
- Vertical overgrowth of the upper jaw: a skeletal pattern where the upper jaw is longer vertically.
- A combination of factors, which is common.
A dermatologist or aesthetic doctor may assess the muscles, while a dentist or orthodontist can help evaluate teeth, gums and jaw structure.
How Botox Treats a Gummy Smile
Several small muscles work together to lift the upper lip when you smile. The most commonly targeted area is a point beside the nostrils where these elevator muscles converge. Injecting a small amount of botulinum toxin here:
- Reduces the strength of the upward pull on the lip.
- Allows the lip to sit slightly lower when you smile.
- Shows less gum while keeping a natural smile.
The amounts used for gummy smile are generally small compared with many other areas. Commonly cited totals are typically in the low single digits of units per side, but the exact amount is decided by your doctor based on muscle strength and symmetry. Precision is especially important here, as too much can affect the smile.
Who Is a Good Candidate?
Botox for a gummy smile may suit people who:
- Have gum display mainly caused by strong lip elevator muscles.
- Have mild to moderate gum show.
- Want a non-surgical, temporary option.
- Want to "test" how a lower lip position looks before considering longer-term options.
It may be less suitable if the cause is mainly skeletal or dental. It is also not recommended during pregnancy or breastfeeding, or for people with certain neuromuscular conditions.
What to Expect From Treatment
The procedure
The treatment usually takes only a few minutes. The doctor asks you to smile to assess the muscle movement, marks injection points, and then injects with a very fine needle. Discomfort is brief and mild.
When results appear
Effects start within a few days, with full results around one to two weeks. A review at around two weeks allows minor adjustments if needed.
How long it lasts
Results commonly last around three to four months, though some people find the effect fades sooner because the treated muscles are small and very active.
Possible Side Effects
Side effects are usually mild and temporary, but because the area is so closely linked to expression, they can be noticeable:
- Small bruises or swelling at injection points.
- A smile that feels slightly stiff or different for a while.
- Asymmetry if one side responds more than the other.
- Upper lip lengthening that looks excessive if too much product is used.
- Rarely, difficulty with certain mouth movements, such as drinking through a straw or pronouncing some sounds.
Choosing an experienced injector and starting conservatively help reduce these risks. Any effects wear off as the toxin does.
Other Options for a Gummy Smile
Depending on the cause, alternative or additional treatments include:
- Lip filler: adding a little volume to the upper lip may slightly reduce gum show in some people.
- Gum contouring: a dental procedure to reshape excess gum tissue.
- Orthodontic treatment: to adjust tooth position.
- Lip repositioning surgery: to limit how high the lip can rise.
- Jaw surgery: for significant skeletal causes.
For visitors to Korea, Botox is a quick, low-downtime option, but remember that results are temporary, so consider how you will maintain them once you return home.
Frequently asked questions
Will Botox change my smile completely?
When done well, it should lower the upper lip slightly while keeping your smile natural. Overcorrection is possible, which is why conservative dosing is often preferred.
Is Botox for gummy smile painful?
Most people find it quick and mildly uncomfortable. Ice or numbing cream can help.
Can it be combined with lip filler?
Yes, some people benefit from both. Your doctor may perform them together or space them out.
Does the result become permanent with repeated treatment?
No. Botox remains temporary, although some people find they can space treatments a little further apart over time.
Get an Accurate Assessment
Botox can be a simple and effective way to soften a gummy smile when the main cause is muscular. Because several factors can contribute, an accurate diagnosis is important. A qualified dermatologist, sometimes working with a dental specialist, can assess your smile and recommend the most suitable treatment.
