Gummy Smile Botox: A Patient's Guide to Treatment in 2026

You may be reading this because you like your smile in photos until the moment you laugh properly. Then all you can see is more gum than you'd like, and it starts to affect how freely you smile.

That's common, and it's something we discuss often in clinic. A gummy smile isn't automatically a dental problem or a “flaw”. In many people, it's about how the upper lip moves when they smile. That distinction matters, because if the cause is muscular, treatment can be surprisingly straightforward.

At our Maidenhead clinic, the conversation around gummy smile Botox is always about balance. The aim isn't to change your face or flatten your expression. It's to soften an overactive lift of the upper lip so your smile looks more harmonious and still feels like you.

What Causes a Gummy Smile and How Does Botox Fix It

Some people notice it in selfies. Others notice it when they're speaking, laughing, or seeing candid wedding photos. The pattern is often the same. At rest, the mouth looks completely normal. When smiling, the upper lip lifts higher than expected and exposes more gum tissue.

That usually points to a lip-dynamic gummy smile. In plain English, the upper lip is being pulled too far upward by specific facial muscles. The main one often involved is the levator labii superioris alaeque nasi, usually shortened to LLSAN.

The muscle issue in simple terms

A useful way to think about it is like a curtain being pulled slightly too high. The curtain itself isn't the problem. The pull is just stronger than it needs to be. In a gummy smile, the upper lip acts a bit like that curtain.

Botulinum toxin works by relaxing the overactive muscle rather than adding volume. It isn't a filler. It doesn't bulk the lip out or reshape your teeth or gums. It reduces the strength of that upward pull so the lip settles lower when you smile.

A 2024 systematic review on gummy smile Botox found that treatment often targets the LLSAN muscle, with a conservative 2 to 3 units generally effective, and peak results commonly seen at 2 to 4 weeks.

A good result doesn't look “done”. It looks like your smile, just less top-heavy.

Why this treatment suits some smiles and not others

Proper assessment matters. Botox works well when the problem is muscle activity. It won't correct a gummy smile caused mainly by tooth position, gum overgrowth, jaw structure, or other dental and skeletal factors.

In practice, that means the consultation is the most important part. We assess your smile at rest, in speech, and in full animation. We're looking at movement, symmetry, and whether the upper lip is the primary driver of what you're seeing in the mirror.

If that's the case, this treatment sits neatly within broader anti-wrinkle injections because the principle is the same. The product relaxes a targeted muscle. The difference is that here, the goal is a softer smile lift rather than a smoother forehead.

What doesn't work is treating a gummy smile as if every patient needs the same dose in the same spot. Anatomy varies. Smile pattern varies. That's why natural outcomes come from careful placement, conservative dosing, and realistic expectations rather than chasing a fixed formula.

Your Treatment Journey at Our Maidenhead Clinic

The first thing most patients want to know is what the appointment feels like. Fair question. The process is usually much simpler than people expect, but it should never feel rushed.

Before treatment

Your journey starts with a consultation, not an injection. We look at your smile from the front and in motion because gummy smiles aren't one-size-fits-all. Some are more central. Some show more gum across a broader width. Some are mixed patterns and need a more customized plan.

That medically led assessment is a big part of why patients choose a health and aesthetic clinic in Maidenhead rather than booking treatment purely on price. The decision isn't just whether Botox can be used. It's whether Botox is the right answer for your anatomy.

During that appointment, we also talk about what result you want. Patients typically prefer subtle changes, aiming to smile freely without feeling their gum line dominates the photo.

On the day

The treatment itself is quick. The injection points are small and precise, and the area doesn't usually require a long appointment. The key is accuracy, not speed for its own sake.

One of the most useful clinical points from the literature is that injection patterns are adjusted to the patient's smile type, and a standardised clinical series reported the best aesthetic outcome at 14 days, with benefits lasting 2 to 3 months before a gradual return toward baseline. That same paper also describes tailoring placement, including lateral nasal-base placement and around a 50% dose reduction on the lateral side for posterior or mixed gummy smiles to reduce overcorrection and asymmetry risk, as outlined in this clinical paper on tailored gummy smile injection patterns.

Clinic reality: The most natural smiles usually come from under-treating slightly at the first visit rather than trying to force a maximal result in one go.

After your appointment

You won't usually walk out with the final result visible immediately. The change builds gradually. That's why we explain the timeline clearly before treatment, so you're not checking the mirror a few hours later and wondering whether anything happened.

What patients tend to find reassuring is the structure of the process:

• First stage: You leave with a personalised plan based on your smile pattern, not a generic injection map.

• Next phase: The area settles over the following days as the muscle activity softens.

• Best point to judge it: We usually ask patients to assess the result once it has had proper time to develop, rather than making a snap decision too early.

If you're considering treatment for an event, don't leave it until the last minute. A wedding, party, work photoshoot, or holiday is much easier to plan for when you've allowed enough time for the smile to settle naturally.

Expected Results Longevity and Maintaining Your Look

The best gummy smile Botox result is subtle. Your smile still lifts. Your upper lip still moves. You still look like yourself. The difference is that the lip doesn't retract so aggressively that the gums become the first thing you notice.

What the timeline usually looks like

The clinical review data gives a helpful framework for expectation-setting. Effects are usually seen within 1 to 2 weeks, they generally last 4 to 6 months, and reduction in gingival display of up to 5 mm has been reported after treatment, according to this UK-relevant clinical review on botulinum toxin for gummy smile. The same review notes that many patients return to baseline by 24 weeks.

That's why I describe it as a treatment you manage rather than a treatment that manages you. It's temporary, which means it's adjustable. If you like a soft change, you can maintain that. If you decide you don't want to repeat it, it wears off.

What natural maintenance looks like

There isn't one “correct” schedule for everyone. Some patients prefer to top up before the effect has fully faded so their smile stays consistent. Others are happy to wait until they notice more gum show returning.

Useful points to keep in mind:

• Temporary is often a benefit: You're not locked into a permanent change.

• Consistency usually matters more than intensity: Gentle, well-timed maintenance tends to look better than chasing a stronger result.

• Your smile can be reassessed over time: Muscle activity, lip behaviour, and your aesthetic preference can all shift.

If you want a broader sense of how longevity works with this category of treatment, our guide on how long anti-wrinkle injections last can help you understand the maintenance side.

Most patients are relieved to hear this isn't permanent. It gives them room to try the treatment, live with it, and decide whether they want to continue.

What doesn't work well is expecting one appointment to permanently solve a dynamic smile pattern. Botox is a smart option for the right candidate, but it's still a temporary neuromodulator, not a structural correction.

Is Gummy Smile Botox Right for You

The strongest candidates for gummy smile Botox are people whose upper lip lifts too far because of muscle hyperactivity. If your smile looks balanced at rest but becomes very gum-heavy when you laugh or grin fully, Botox may be worth considering.

Who tends to suit it best

This treatment usually makes sense when you want a non-surgical change and your main concern is the lip lifting high rather than the teeth, gums, or jaw being the primary issue. It can also suit people who want a reversible option before committing to anything more invasive.

Good candidates are often looking for:

• A subtle adjustment: You want less gum show, not a different face.

• Minimal interruption: You don't want major downtime.

• Flexibility: You like the idea that the result can be maintained, modified, or allowed to wear off.

When Botox may not be the right answer

Some gummy smiles are driven more by dental position, gum tissue, or underlying skeletal structure. In those cases, Botox can be the wrong tool. It may soften the appearance slightly, but it won't fix the root cause.

That's also why treating this area casually can backfire. If placement is off or the plan doesn't match the smile type, you can end up with an unnatural upper lip position, asymmetry, or an odd change in smile mechanics.

The safest treatment is often the one you're advised not to have. A proper consultation should include that possibility.

Why practitioner choice matters

This is a small treatment area, but small areas demand precision. The injector has to understand not just product handling, but facial movement, balance, and how different smile patterns behave.

At a medically led clinic, the value is in the assessment as much as the injection. You want someone who can distinguish between a muscular gummy smile and one that really belongs in a dental or surgical pathway. That protects both your outcome and your safety.

If Botox is suitable, conservative treatment usually gives the most believable result. If it isn't suitable, the honest answer should be clear from the start.

Cost and Alternative Treatment Options

Cost matters, but so does context. For gummy smile concerns, the key question isn't just “What does Botox cost?” It's “What treatment matches the cause of my smile, and what level of intervention am I comfortable with?”

Because dosing and injection pattern vary by anatomy, clinics usually price this after assessment rather than offering a one-price-fits-all promise. That's sensible. A smile that needs simple central softening isn't the same as one that needs more nuanced balancing across a mixed pattern.

How Botox compares with other options

Some patients also ask whether filler can help, or whether gum or jaw procedures would be more appropriate. The answer depends on the reason for the gummy smile.

Treatment	Invasiveness	Longevity	Typical Cost (UK)	Best For
Botox	Minimally invasive injection treatment	Temporary	Varies by clinic and anatomy	Lip-dynamic gummy smiles caused mainly by overactive upper lip movement
Dermal filler	Minimally invasive injection treatment	Temporary	Varies by clinic and product used	Selected cases where lip support or balance is part of the concern, not pure muscle pull
Gingival surgery such as gingivectomy or laser gum contouring	More invasive than injectable treatment	Longer-lasting than Botox	Usually higher than injectable treatment	Cases where gum tissue is the main issue
Orthodontic or jaw-based correction	Most invasive pathway	Structural and longer-term	Usually the highest cost route	Skeletal or dental causes rather than muscle-driven smile movement

If you're weighing up gum-focused procedures, this guide to understanding laser gum treatment options is a useful starting point because it explains when gum contouring belongs in the conversation.

Where filler fits and where it doesn't

People are often surprised to hear that filler isn't a direct replacement for Botox here. Filler adds volume or support. Botox reduces muscle pull. Those are different jobs.

In selected cases, a practitioner may discuss lip support as part of an overall smile plan. Our article on lip filler for gummy smile concerns explains where that approach may complement treatment and where it won't.

If you're deciding between options, don't choose based on the least expensive line item alone. Choose based on the cause. The cheapest wrong treatment is still the wrong treatment.

Aftercare and Frequently Asked Questions

Aftercare for gummy smile Botox is usually simple, but small details matter because this is a very precise treatment area.

Aftercare that helps the result settle well

• Keep the area undisturbed: Don't press, rub, or massage the injection site unless your practitioner has told you otherwise.

• Stay upright for a while after treatment: This is standard advice with anti-wrinkle treatments and helps keep the area settled.

• Leave strenuous activity for later if advised: A quiet day is often more sensible than going straight into a demanding workout.

• Follow your individual clinic guidance: If your practitioner gives you specific instructions based on your smile pattern or treatment plan, those take priority.

• Be patient with the mirror: Early checking causes unnecessary worry because the effect develops gradually rather than instantly.

Common questions patients ask

Will it hurt

Most patients describe it as very manageable. The injections are small and quick. For many people, the anticipation is worse than the treatment itself.

Will I look unnatural

That shouldn't be the aim. A well-planned result softens the lip lift without making the mouth look stiff or oddly flat. The right outcome is a smile that looks balanced, not restricted.

Can I combine it with lip filler

Sometimes, yes, but only when there's a clear reason. Botox and filler solve different problems. Combining them can work in selected patients, but it should never be automatic.

What if I don't like it

This is one reason many patients feel comfortable trying it. The effect is temporary. If you decide it isn't for you, it gradually wears off rather than leaving a permanent change.

Are there risks

Yes, and it's better to discuss them openly. Potential issues can include asymmetry, overcorrection, undercorrection, or a smile that doesn't move as expected. Those risks are exactly why assessment, dosing, and placement matter so much.

If a treatment is sold as effortless and risk-free, the conversation probably isn't careful enough.

Can I go back to normal straight away

It's usually an easy treatment to fit around work and daily life, provided you follow the aftercare advice you've been given.

Smile with Confidence Your Next Step

You might already know the feeling. You smile in a photo, then look at it and focus on how much gum shows instead of the smile itself. For the right patient, gummy smile Botox can be a simple medical treatment that softens that upper lip lift and helps the smile look more balanced.

Results depend on careful assessment, precise placement, and realistic expectations. In clinic, that matters more than speed or trends. A good result should sit quietly within your expression, so you still look like yourself when you laugh, talk, and smile.

At Youthful Revival in Maidenhead, the patient journey starts with an honest consultation. We assess how your lip moves, how much gum shows, and whether Botox is likely to give the kind of change you want. In some cases, it is a good fit. In others, another approach makes more sense, and it is better to say that clearly from the start.

If you have been covering your mouth when you smile, holding back in photos, or if you want a professional opinion before deciding, a consultation is the right next step. You should leave with a clear view of the cause, the likely outcome, and whether treatment fits your goals.
