A gummy smile happens when the upper lip rises higher than usual during a smile, showing more gum tissue above the front teeth than most people find balanced. Botox is one of the most effective non-surgical treatments for a gummy smile because it relaxes the small muscles that lift the upper lip, letting the lip settle into a more proportionate position. Most patients notice softer, more balanced results within three to five days, with full effects visible by about two weeks, and there is no downtime involved.
What Is a Gummy Smile?
A gummy smile, sometimes called excessive gingival display, describes a smile where more than three to four millimeters of gum tissue shows above the upper teeth. A small amount of gum show, generally two to three millimeters, is considered a normal and even attractive part of a natural smile. When the amount exceeds that range, the smile can look unbalanced, even if the teeth themselves are healthy and well-aligned.
The condition is extremely common and has nothing to do with oral hygiene or dental health. It is a cosmetic concern rooted in muscle activity, bone structure, tooth size, or gum tissue, and in many cases more than one of these factors overlaps.
Many people with a gummy smile feel self-conscious about laughing openly or smiling for photos, even though their teeth and gums are perfectly healthy. This is purely an aesthetic proportion issue, and it is one of the most common concerns raised during cosmetic consultations. Recognizing that a gummy smile is a normal variation in facial anatomy, rather than a flaw, is often the first step toward feeling comfortable exploring treatment options.
What Causes Excess Gum Show When You Smile?
Several structural and muscular factors can contribute to a gummy smile, including:
- Hyperactive upper lip muscles, particularly the levator labii superioris alaeque nasi, which pull the lip higher than average during a smile
- A naturally short upper lip that exposes more gum tissue at rest and while smiling
- Vertical maxillary excess, a bone-related condition where the upper jaw grows slightly longer than average
- Teeth that appear small relative to the surrounding gum tissue
- Gum tissue that has grown down over more of the tooth surface than usual, sometimes called gingival hypertrophy
Identifying which of these factors applies is important because it directly affects which treatment will actually work. A muscle-driven gummy smile, for example, responds very well to Botox because the excess lip movement is the root cause. A bone-driven gummy smile, on the other hand, will show only modest improvement from Botox alone, since the underlying skeletal proportions remain unchanged. This is why an in-person evaluation, rather than a self-diagnosis based on photos, gives the most accurate treatment recommendation.
A physician with more than two decades of experience in aesthetic medicine, Dr. Violetta Berdichevskaya at Avellina Aesthetics, evaluates each patient’s smile individually to identify which of these factors is driving the gum show before recommending a treatment plan, since muscle-related gummy smiles typically respond best to Botox.
How Botox Works for Gummy Smile Correction
Botox treats a gummy smile by targeting the muscle responsible for lifting the upper lip too high. A small, precise dose is injected into the muscle on each side of the nose, just above the corners of the mouth. Once the muscle receives less signal to contract, the upper lip rises less dramatically when smiling, which reduces the amount of visible gum tissue without changing how the rest of the face moves.
This approach relies on the same neuromodulator technique used in Botox treatment across Philadelphia for wrinkle reduction, simply applied in a much smaller dose and a different muscle group. Speech, chewing, and normal lip movement are not affected, and the surrounding smile muscles continue to work as they always have.
This treatment is sometimes grouped with the cosmetic lip flip, since both use Botox near the upper lip, though gummy smile correction targets a slightly different injection point aimed specifically at reducing gum show rather than reshaping lip fullness. Because only one of several muscles that lift the lip is treated, the remaining muscles continue supporting a balanced, natural-looking smile, which is why results tend to look proportionate rather than frozen.
Botox for Gummy Smile: What to Expect
The treatment process is straightforward and typically follows these steps:
- A smile assessment is performed to measure how much gum shows and to confirm the cause is muscular rather than bone-related
- Two to six units of Botox, on average, are mapped and injected on each side of the upper lip elevator muscles
- The injections themselves take roughly ten to fifteen minutes, with only mild, brief discomfort
- Patients resume normal activities immediately, avoiding strenuous exercise and lying flat for a few hours
- A brief follow-up may be scheduled at two weeks to fine-tune results if needed
Most patients benefit from a personal consultation to review dosage, placement, and expected outcomes beforehand, since the right unit count depends on lip length, smile pattern, and how strongly the muscle contracts.
Results and Recovery Timeline
Gummy smile Botox is a low-downtime treatment, but results build gradually rather than appearing instantly:
- Days 1 to 3: mild swelling or small injection marks may be present, with no visible change yet
- Days 3 to 5: the upper lip begins to sit lower during a smile as the muscle relaxes
- Weeks 1 to 2: full results are visible and the smile appears balanced
- Months 3 to 4: the effect gradually fades as muscle activity returns to normal
Because the results are temporary, many patients build these touch-up visits into their ongoing beauty routine to keep their smile consistently balanced throughout the year.
Am I a Good Candidate for Gummy Smile Botox?
Gummy smile Botox tends to work best for patients who meet the following criteria:
- A mild to moderate gummy smile caused primarily by an overactive lip muscle rather than bone structure
- General good health with no known sensitivity to botulinum toxin
- Realistic expectations about the temporary, muscle-relaxing nature of the treatment
- Not currently pregnant or breastfeeding
Patients whose gummy smile is caused mainly by bone structure or gum tissue overgrowth may see only partial improvement from Botox alone, which is why an accurate diagnosis matters. Topics such as how much gum show is considered a gummy smile and gummy smile surgery versus Botox comparison are worth exploring further for patients weighing multiple options.
Botox vs. Other Gummy Smile Treatments
Botox is not the only option for correcting a gummy smile, and the right choice depends on the underlying cause:
Botox Injections
Non-surgical, temporary, and ideal when an overactive lip muscle is the main cause. Results last three to four months and require no recovery time.
Lip Repositioning Surgery
A permanent surgical option typically reserved for cases involving significant bone or lip-length factors that Botox cannot fully address.
Orthodontics or Veneers
Better suited to cases where small teeth relative to the gumline are the primary concern, rather than muscle activity.
Complementary Lip Enhancement
Some patients choose to pair Botox with dermal fillers for subtle upper lip volume, which can further soften the balance between lip and gum tissue for a fuller-looking smile.
Choosing the Right Provider for Gummy Smile Botox
Precision matters more with gummy smile Botox than with many other injection areas, since the muscles involved are small and closely positioned near the nose and mouth. Overcorrection can flatten the smile or affect lip mobility, so the treatment should always be performed by an experienced, medically trained injector who maps each injection point individually.
Ask any provider you are considering how many gummy smile cases they treat, how they determine unit dosing, and what their approach is if the first result needs slight adjustment at the two-week follow-up. A provider who takes time to answer these questions in detail, rather than offering a generic quote over the phone, is generally a strong sign of the kind of individualized care this treatment requires.
Scheduling a consultation allows your injector to map out precise injection points before treatment begins and confirm that Botox is the right fit for your smile pattern. You can request an appointment online or call the office directly to get started.

Frequently Asked Questions
Most patients need between two and six units per side, for a total of roughly four to twelve units, depending on lip length and muscle strength.
No. The dose used is small and targeted, so normal speech, chewing, and lip function remain unaffected.
Results typically last three to four months before the muscle gradually regains its normal activity and a touch-up is needed.
Discomfort is minimal. The needle used is very fine, and most patients describe the sensation as a brief pinch.
Botox is temporary by design. Patients seeking a permanent correction for bone-related cases may want to discuss surgical options instead.
Pricing depends on the number of units required, which varies from patient to patient. Exact costs are typically discussed during a consultation.
