The short answer

  • A gummy smile is not one problem. It can come from an over-active upper lip, a short lip, excess gum tissue, worn teeth, or a long upper jaw. Each has a different fix.
  • Botox only fixes the muscular type. A small dose relaxes the muscles that lift your upper lip so less gum shows when you smile. It works well when the muscle is the cause and does nothing when it is not.
  • A lip flip or lip filler can help when a short or thin upper lip is part of the picture, by letting the lip cover more of the gum.
  • Gum tissue and jaw causes need a specialist. Excess gum is a periodontist's job (a gum lift); a long upper jaw is a maxillofacial surgeon's job. Injectables will not fix either, and an honest clinic says so.
  • In Dubai a Botox gummy smile correction is roughly AED 600–900, because it uses a very small, precise dose. This is a job for an experienced, DHA-licensed injector.

Plenty of people describe a gummy smile as a small, fixable thing, and often it is. But the reason it goes wrong for some patients is that they treat it as a single problem with a single solution, usually Botox, when the real cause sits somewhere else entirely. A few units in the wrong situation buys you three months of nothing.

So this guide starts with the cause. Once you know why your gum shows, the right treatment is obvious, and you can walk into a Dubai consultation already knowing whether you are looking at a quick injectable, a lip treatment, or a conversation with a dentist or surgeon.

What a gummy smile actually is

A gummy smile, known clinically as excessive gingival display, simply means that more of your upper gum shows than most people find balanced when you smile fully. There is no strict medical threshold, but roughly three to four millimetres or more of visible gum at a full smile is the point at which many people start to notice it and ask about it.

It is a cosmetic concern, not a health problem, and a lot of people who have one never think about it. If yours bothers you, though, the good news is that it is one of the more treatable aesthetic concerns, provided the treatment matches the cause. That last part is the whole game.

The causes, and why the cause decides the fix

Your gum can show for several different reasons, and sometimes for more than one at once. This is the single most important table in this guide, because it tells you which specialist and which treatment your case actually points to.

The causeWhat it looks likeWho fixes it
Hyperactive upper-lip musclesThe lip lifts high and fast when you smile, exposing gum, but sits normally at rest.Botox (the ideal case)
Short or hypermobile upper lipA naturally short lip, or one that travels a long way up, so it cannot cover the gum.Lip flip or filler, sometimes Botox
Excess or low gum tissue (gingival)A lot of gum shows even at rest; teeth can look short.Periodontist / dentist (gum lift)
Vertical maxillary excess (jaw)The whole upper jaw is long; teeth and gum sit high in the face.Maxillofacial surgeon (jaw surgery)
Worn or short teethTeeth look small relative to the gum, altering the ratio.Dentist (crowns / veneers)

The honest headline: Botox only solves the first type, the over-active muscle, and it can help with a short lip in some cases. It does nothing for excess gum tissue, a long jaw, or worn teeth. A clinic that offers you Botox without first working out which of these you are is either guessing or selling. A good injector looks at your smile at rest and in full motion, measures how far your lip travels, and refers you on if the cause is not muscular.

Botox for the muscular type

When the cause is a muscle that lifts the upper lip too hard, Botox is the mainstay treatment and the least invasive option by a wide margin. The muscles involved sit beside the nose and along the upper lip; when they over-contract, they haul the lip up and expose the gum. A very small, precise dose of botulinum toxin relaxes those muscles just enough that the lip does not lift as high, so less gum shows when you smile.

Botox is botulinum toxin type A. Injected in tiny controlled amounts, it temporarily blocks the nerve signal to a specific muscle so that muscle stops contracting as strongly. That is the same mechanism the US Food and Drug Administration describes for its approved cosmetic uses, and the same reason the effect is temporary: as the nerve signal returns over about three to four months, the muscle regains its pull. For the mechanics of dosing, brands and per-unit pricing, our full guide to Botox in Dubai goes deeper, and if you are weighing this against volume treatments, Botox vs fillers in Dubai lays out which concern belongs to which tool.

The appeal here is real: a muscular gummy smile can often be softened with just 2–4 units total, no downtime, and a result that settles within a couple of weeks. The catch is precision, which the next sections cover, because this is not an area where more product is better.

Good to know

Precision matters more here than almost anywhere else on the face. The muscles that lift your lip sit right next to the ones you smile and speak with. A poorly placed few units can leave the upper lip looking heavy, flat or asymmetric, or your smile looking uneven, until it wears off months later. A small, symmetric dose from an experienced injector is the whole difference between a natural result and an odd one.

When a lip flip or filler helps

Sometimes the muscle is not the only issue. If your upper lip is naturally short or thin, it simply cannot cover as much gum, and relaxing a muscle only goes so far. In those cases a lip treatment can be part of the answer.

A lip flip uses a few units of Botox in the muscle around the mouth to let the upper lip roll gently outward, showing a little more of the lip and covering a little more gum, without adding any volume. It is subtle and short-lived, around six to eight weeks, which makes it a low-commitment way to see whether repositioning the lip improves your smile. A conservative amount of lip filler can do something similar by adding a small amount of height and fullness to a thin upper lip, so it drapes lower over the gum line. Neither of these is a fix for excess gum tissue or a long jaw; they help only when a short or thin lip is genuinely part of the picture, and often they work best alongside a small muscular dose rather than instead of it.

The point of naming all three options is honesty about scope. Injectables are excellent for the muscular and lip-driven versions of a gummy smile. Pushed beyond that, they stop working, and a responsible clinic will not keep selling you units for a problem that lives in your gums or your jawbone.

When it is dental or skeletal, and injectables are not the answer

This is the part most gummy-smile marketing skips. If a lot of gum shows even when your face is completely at rest, the likely cause is the gum tissue itself, and the right person to see is a periodontist or dentist. A gum lift, or crown lengthening, reshapes the gum line so more tooth and less gum shows. It is a minor dental procedure with a lasting result, and no amount of Botox reproduces it, because the issue is tissue, not muscle.

If instead your whole upper jaw looks long, with the teeth and gum set high in your face, the cause may be skeletal, known as vertical maxillary excess. The definitive correction there is orthognathic (jaw) surgery, carried out by a maxillofacial surgeon, sometimes alongside orthodontics. It is a bigger decision than an injectable by a long way, and it is not something anyone should be steered into lightly, but for a genuinely skeletal cause it is the honest answer, and injectables are not a substitute. Worn or short teeth are a third, separate story, corrected by a dentist with crowns or veneers to rebalance the tooth-to-gum ratio.

None of this means Botox is a bad option. It means Botox is the right option for one specific cause. Knowing which camp you fall into before you book saves you from paying for a treatment that was never going to hold.

What to expect: dosing, onset and maintenance

For a muscular gummy smile, the treatment itself is quick. After assessing how your lip moves, the injector places a small, symmetric dose, typically 2–4 units in total, into a precise point on each side. There is little to no downtime, and you can usually return to your day straight away, avoiding heat, heavy exercise and rubbing the area for the first day.

The effect is gradual, not instant. You will usually start to see the change within a few days, with the full result settling by around two weeks, which is also the point at which a good clinic reviews you and makes any tiny adjustment. Because the dose is so small, over-treatment is the main thing to avoid: too many units, or units placed slightly off, can make the upper lip look heavy or the smile asymmetric. This is exactly why the injector's experience matters more than the headline price.

Maintenance is straightforward but ongoing. The result lasts roughly three to four months, in line with how botulinum toxin behaves elsewhere on the face, after which the muscle regains its lift and the gum begins to show again. Most people who are happy with it repeat the treatment two or three times a year. There is no obligation to keep it up; if you stop, your smile simply returns to how it was before, with nothing lost.

One more honest note on who should do this. A gummy smile correction is a small line on a price list, which tempts some places to offer it as a cheap add-on. Resist that framing. The margin for error here is a millimetre or two, and the cost of getting it wrong is a lopsided smile for a season. Treat it as a job for a skilled, licensed injector, and take two minutes to verify the clinic and injector on the DHA registry before you book.

What gummy smile treatment costs in Dubai in 2026

Because the same visible concern can have very different causes, the prices below cover the non-surgical, injectable routes. Surgical options such as a gum lift or jaw surgery are quoted separately by a periodontist or surgeon and cost considerably more, because they change tissue or bone permanently.

TreatmentWhat it addressesTypical Dubai price (2026)
Botox gummy smile correctionOver-active upper-lip muscleAED 600 – 900
Lip flipShort lip, subtle repositioningAED 400 – 700
Lip flip with gummy smile correctionMuscle plus lip togetherAED 700 – 1,100
Conservative lip filler (0.5ml)Thin upper lip, added heightAED 1,200 – 1,800

A note on suspiciously cheap offers. A Botox gummy smile correction is inexpensive because it uses so few units, not because it is trivial, so do not choose on price alone here of all places. Ask which product is being used, how many units, and who is injecting. For a full breakdown across every treatment, see our UAE aesthetic price guide. And if you are a man weighing this up, muscle bulk changes the dosing slightly; our guide to Botox for men in Dubai covers the natural-look approach and why the numbers differ.
