A balanced smile looks effortless, which is why a gummy smile can feel distracting to the person who has it. When more than 2 to 3 millimeters of gum show on a full smile, the lip-to-tooth ratio skews bright and bouncy, not always the look someone wants in photos or meetings. If you see mostly pink before white, you are not alone, and it is not a flaw. It is simply anatomy at work. Botox for gummy smile offers a precise, reversible way to restore proportion, often in minutes, with results that read as natural rather than “done.” This is a guide to what actually happens during the Botox procedure for gummy smile correction, the anatomy behind it, when it excels, and when other options might be better.
What makes a smile look “gummy”
Most gummy smiles come from a combination of three factors. The first is hyperactive elevator muscles of the upper lip, mainly the levator labii superioris alaeque nasi, levator labii superioris, levator anguli oris, and zygomaticus minor. These muscles pull the upper lip up and back when you smile. If they overperform, your lip elevates higher than average and more gum shows. The second factor is tooth eruption and gum display. Short clinical crowns, high gingival margins, or altered passive eruption can make teeth look stubby and gums look prominent. The third is skeletal pattern. A long midface or vertical maxillary excess sets the entire gum-to-lip relationship higher.
Botox, or botulinum toxin type A, affects muscle activity, not bone or tooth length. That matters for results. If your gummy smile mostly comes from an over-lifting lip, Botox injections can lower the curtain smoothly. If your gum display comes from short teeth or a long upper jaw, you may need a dentist or surgeon to change the hardware, not just the software.
How Botox works when used thoughtfully
At its core, Botox therapy reduces the release of acetylcholine at the neuromuscular junction. In plain terms, it quiets a muscle’s ability to contract. For lines around the eyes or forehead, that means softer expression lines and fewer creases. For a gummy smile, it means the upper lip does not jump as high when you grin. You still smile. You still look like you. The lip simply stops overshooting.
In practice, clinicians target key muscle junctions that lift the lip. The most common point is the so-called Yonsei point near the side of the nose, where several lip elevators overlap. Some injectors add a tiny unit at the medial part of the zygomaticus minor or near the depressor septi nasi if the nasal tip pulls down and the lip climbs up together. Dosing is small compared to Botox for forehead lines or Botox for frown lines. Where 10 to 20 units might land across the glabella or crow’s feet, gummy smile correction often uses a total of 2 to 6 units spread across two to four points. I prefer to start lower, reassess at two weeks, and add more if needed. That approach avoids overcorrection and frozen-looking smiles.
Who tends to be a good candidate
Patterns emerge after you have treated enough faces. People who lift their upper lip high yet have normal tooth size tend to do beautifully with subtle Botox cosmetic adjustments. If someone can relax the top lip by saying “Emma” and the smile suddenly looks balanced, there is a good chance small amounts of toxin will deliver that same balance without changing the character of their expression.
Patients with altered passive eruption, gummy display from orthodontic relapse, or very short incisors often benefit from dental contouring or periodontal work first. In select cases, pairing dental treatment with Botox for lip modulation offers the best outcome. When vertical maxillary excess is the driver, surgical options like orthognathic surgery remain the definitive fix, while Botox offers a temporary, low-commitment preview of decreased gingival show.
A look at the appointment, minute by minute
The Botox procedure for gummy smile is efficient. After photos give you a baseline and help you see subtle differences later. We map your smile at rest, half-smile, and full smile. I palpate the lip elevators to see which ones dominate. Some people recruit strongly near the nose, others more laterally. That influences where I place the needle and how many units I draw.
Cleansing takes seconds. I use a 30 or 32 gauge needle and a conservative initial dose. Two small injections, one on each side, often suffice. If the depressor septi nasi is active, a midline micro-dose may help the nasal tip stop tugging downward when you smile. The entire Botox treatment typically takes less than ten minutes. You can go back to work without obvious marks other than a pinprick or two.

People ask about pain. On a zero to ten scale, most rate these Botox injections as a two or three. The upper lip area is sensitive, but the needle is tiny, and the volume of fluid is small.
What to expect after treatment
Botox does not work instantly. You will feel normal the first 24 to 48 hours. By day three to five, most people notice the upper lip no longer springs as high. Full effect lands around day seven to fourteen. I book a two-week check for new patients, especially first time Botox users, to make sure the lift is even and to add a micro tweak if one side still climbs.
Results typically last eight to twelve weeks in the lip elevators, sometimes up to sixteen weeks in low-metabolism patients. Smiling is frequent and dynamic, so the effect can fade faster than in areas like the glabella. Plan seasonal Botox maintenance if you like the look. Some prefer “Baby Botox” or “Micro Botox” dosing to keep movement soft without any hint of stiffness. That approach can work well in this area.
Downtime is effectively none. Avoid heavy exercise, saunas, and pressing on the treated area for the first day. Skip facials and masks that might rub the area for 24 hours. Makeup is fine after a few hours if the skin looks closed and calm.
Natural results without a “frozen” smile
The art is in the dose and placement. Overdo it, and the upper lip can look heavy or even lengthened, which flattens your smile shape and can change how you enunciate certain consonants. Done well, Botox for gummy smile lowers gum show by 1 to 3 millimeters and preserves the lip’s curvature. This is not Botox for face slimming or Botox for masseter, where the contour shift is slow and subtle over weeks. Here, the effect is clear and quick, so nuance matters.
People who use Botox for anti aging around the eyes and forehead often worry about compounding stiffness. A skilled injector accounts for the whole face. If you already have Botox for crow’s feet and bunny lines along the nose, doses must be balanced. Treating bunny lines and a gummy smile together can yield a smooth, cohesive smile, yet the injector must respect how these muscle groups interplay so that smiling still looks animated, not flat.
The role of the lip flip and fillers
The lip flip, a micro dose of Botox to the orbicularis oris along the vermilion border, can pair nicely with gummy smile treatment in select faces. By softening the ring muscle that purses the lips, the upper lip can evert slightly. That adds the illusion of volume without filler and can offset any sense of upper lip shortening. However, too much toxin around the mouth risks difficulty with straws or whistling. Tiny amounts and careful selection matter.
Dermal fillers occupy a different lane. If lip thinness contributes to gum show because the lip curls inward on smiling, subtle filler can support structure and reduce inversion. Still, filler cannot relax overactive elevators. Many of us combine minimal filler for support with Botox cosmetic injection at the elevators for balance. Think of filler as scaffolding and Botox as a gentle dimmer switch.
When Botox is not the right tool
If you show a lot of gum even when the lip barely moves, the teeth and gums need evaluation. Periodontal crown lengthening, orthognathic surgery, or orthodontic intrusion can lengthen teeth or reposition jaws for durable change. Botox in that context acts as a temporary, non surgical Botox alternative to test-drive a milder result or to smooth a small residual lift after dental work.
Another caution: if the smile asymmetry stems from previous surgery or nerve injury, toxin may balance one side botox near Boston Massachusetts but could also unmask other imbalances. A careful exam and honest conversation help set realistic expectations.
Safety profile, side effects, and how we avoid trouble
Botox safety in experienced hands is excellent. The injections for gummy smile use low doses at shallow depths. The biggest risk is overcorrection, which translates to a heavy or droopy upper lip at full smile. That resolves as the product wears off, generally within six to ten weeks in this region. Unevenness can happen if one side’s muscle dominance differs from the other. We minimize that by testing your smile in different expressions and calibrating doses.
Bruising is uncommon but possible, especially if you take fish oil, aspirin, or other anticoagulants. Small nodules from injection fluid disappear within an hour. Headache is rare with such small dosing. True allergic reactions are exceptionally rare. If you are pregnant or breastfeeding, postpone treatment. If you have a neuromuscular disorder or are on certain antibiotics like aminoglycosides, disclose that fully. A board certified Botox doctor, dermatologist, or trained Botox nurse injector should walk through your history and tailor your plan.
Comparing Botox for gummy smile with other facial uses
Many people first meet Botox as a tool for wrinkles. Botox for forehead lines and Botox for frown lines soften the upper third of the face. Botox for brow lift or eyebrow lift uses gentle lateral dosing to tilt the brows open. Around the eyes, Botox for crow’s feet, under eye wrinkles, and bunny lines polish the periorbital and nasal region. Below the nose, we can treat chin dimpling or a pebble chin, the orange peel texture that appears when the mentalis muscle overfires. Each zone requires a different mental map.
Gummy smile correction sits at the junction of function and aesthetics. Unlike static lines, we are tuning a dynamic expression. The doses are lighter, the muscles are smaller, and the feedback loop is faster. This is where a conservative mindset and a follow-up plan matter more than bravado.
Cost, timing, and value
Pricing varies widely by city, injector experience, and whether clinics charge by unit or by area. In most markets, gummy smile treatment uses very few units, so the Botox cost is typically on the lower end compared with larger areas like the forehead. Expect a range that reflects 2 to 6 units at your local per-unit price. While “Affordable Botox” and “Botox deals” appear online often, the better question is value: precise dosing, medical oversight, and a plan for touch-ups often save money and frustration in the long run.
If you are preparing for a wedding or an important event, schedule your first session at least four weeks ahead. That gives time for the two-week check and any micro-adjustment. If you already know your dosing sweet spot, two weeks lead time is usually enough.
How long it lasts, and how it fades
The toxin’s effect peaks at about two weeks, then gradually softens. Most people notice wear-off at two to three months in the upper lip elevators. If your metabolism is fast or you exercise intensely, you may see a shorter window. Those who keep up consistent Botox maintenance sometimes find the lift remains better even as the product wears off, because the muscles unlearn a bit of their overactivity. It is subtle, not permanent, but real.
When does Botox wear off entirely? By the three to four month mark, most of the effect is gone. If you skip a cycle, nothing rebounds worse than baseline. You return to your natural movement and gum display.
What a careful injector looks for in assessment
We watch your lip at rest and in motion. The ratio of pink to white in a soft smile versus a full laugh matters. We look for nasal tip depression on smiling, which points to depressor septi nasi involvement. The philtral column length, lip thickness, tooth size, and gingival margin height all influence dosing. We check for asymmetry in zygomatic recruitment as you smile wider. Sometimes the left side recruits laterally more strongly, which calls for a fractional dose difference. Small choices like injector angle and depth at the Yonsei point can separate a good outcome from a great one.
I also ask about habits like mouth breathing, bruxism, or orthodontic history. For patients with masseter hypertrophy, Botox for masseter or Botox for TMJ can reshape the jawline and reduce jaw clenching, but that is a separate project. Still, it changes facial balance and may influence how the smile reads on camera.
A patient story that captures the nuance
A designer in her thirties came in after trying filler elsewhere that made her upper lip look puffy from the side but did not fix the gummy smile. At rest she looked fine. On smiling, 4 millimeters of gingiva showed from canine to canine, and the nasal tip dipped. We used four units total, two per side near the alar base, and 1 unit midline for the depressor septi nasi. At two weeks, gingival display dropped to roughly 1 to 2 millimeters, the philtrum looked a touch longer in motion but natural, and her photos finally matched how she felt she looked. At her six-week check, we added a micro lip flip with 1 unit per side to soften inversion. The results read like her, just calmer.
Managing expectations and understanding trade-offs
Subtlety is the goal. The trade-off is that you may not eradicate all gum show, especially if the skeletal base contributes. I often tell patients to expect a 30 to 60 percent improvement from Botox alone in lip-dominant gummy smiles. That reduction, paired with the preservation of expression, usually hits the sweet spot. If you chase a 100 percent fix with higher doses, you risk a flat, heavy upper lip. It is better to accept a millimeter of gum than to lose personality in your smile.
Where Botox fits in a full-face strategy
A smile lives within a face. Treating a gummy smile in isolation can unmask other imbalances. If a patient has strong bunny lines, softening them at the same visit can keep the nose bridge smooth on smiling. If they have dynamic vertical lip lines, a trace of Micro Botox may help without compromising function. For someone worried about sagging skin at the jawline, Botox for platysma bands or the so-called Nefertiti lift might sharpen the lower face, though that is unrelated to the smile itself. Handled together, these choices create harmony rather than a patchwork of tweaks.
Botox for wrinkles around the eyes, Botox for forehead lines, and Botox for frown lines remain the staples. A gummy smile correction adds a precise final polish. When someone asks why you look so friendly in photos lately, they should not be able to pinpoint a single feature. They should just see you.
Practical aftercare and what not to do
The first day matters more than most people think. Avoid firm massage around the nose and upper lip. Try not to take a hot yoga class or sit in a steam room. Keep your head above your heart for a few hours. Smile normally. You do not need to “exercise” the toxin in or avoid smiling altogether. If a tiny bruise appears, arnica gel helps. If you feel uneven at day five, do not panic. Asymmetries often even out by day ten. If not, a micro touch-up solves it.
When to consider alternatives
If you are chasing a permanent change and do not want ongoing visits, Botox is not your last stop. A periodontist can assess crown lengthening to show more tooth and less gum. An orthodontist can intrude teeth in select cases. A maxillofacial surgeon can address vertical maxillary excess with orthognathic surgery for a skeletal solution. For some, a lip repositioning procedure in which the upper lip mucosa is advanced can reduce elevator pull surgically. These paths vary in invasiveness, cost, and recovery, but they are options for those who want a one-time solution.
Choosing the right provider
Credentials matter. A board certified Botox provider who treats smiles often will understand dosing finesse in the perinasal area. Ask to see Botox before and after photos for gummy smile specifically, not just general Botox for face results. Discuss your goals in millimeters if possible. A good injector will talk you out of too much product and will schedule the two-week check as part of the plan. Price matters, but a steady hand and judgment matter more.
A quick reference checklist for patients
- Look for a provider who regularly treats gummy smile and can explain your specific anatomy. Start with a conservative dose, then reassess at two weeks for symmetry and smile shape. Plan treatment two to four weeks before major events to allow for adjustments. Avoid heat, heavy exercise, and pressure on the area for 24 hours after injections. Keep expectations realistic: aim for balanced, not rigidly perfect, gum-to-tooth display.
The bigger picture: confidence without overcorrection
When done well, Botox for gummy smile does not erase your expressions. It edits them. The upper lip settles slightly lower, your teeth frame the smile naturally, and your gums no longer lead the show. People often describe feeling more at ease laughing without covering their mouth. The fix is quick, reversible, and adjustable, which makes it a smart first step for those unsure about more invasive options.
Botox is a tool, not a personality transplant. It shines when tailored to your anatomy and your habits. If you already use Botox for expression lines or for headache relief due to chronic migraine, you understand how much dosing and placement matter. Apply that same mindset here. The best results do not advertise themselves. They simply let you enjoy your smile without thinking about it.
