Gum Contouring & the Gummy Smile: Causes, Treatments and What to Expect

A "gummy smile" is the everyday name for excessive gingival display: when more gum tissue shows above the upper front teeth than most people find balanced at a full smile. Clinicians usually treat 1 to 2 millimetres of gum on show as normal and pleasing.

Once the band of visible gum reaches roughly 3 to 4 millimetres or more, many patients begin to feel their smile looks "toothy" or short, even when the teeth themselves are perfectly healthy. It is worth saying plainly: a gummy smile is an aesthetic observation, not a disease. Your gums can show a lot and still be completely healthy.

That distinction matters, because the visible gum line is the meeting point of several separate things — the height and shape of your gums, the length of your tooth crowns, the position of your upper lip, how high that lip lifts when you smile, and the underlying bone and jaw position. A change in any one of these can tip an otherwise even smile towards looking gummy.

Because of that, two people with an almost identical amount of gum on display can need very different treatments, and a careful diagnosis comes before any procedure.

The gum tissue you see frames each tooth like the setting around a stone. When the framing is uneven — one tooth looking shorter than its neighbour, or the gum scalloping sitting at different heights left to right — the eye reads the smile as unbalanced long before it counts millimetres.

This is why gum work sits squarely inside cosmetic dentistry and is often the quiet first step of a wider smile makeover. Getting the gum architecture right can make teeth look longer, more symmetrical and more proportioned without touching the teeth at all.

It also helps to separate cosmetic gum reshaping from the management of gum disease. Reshaping healthy gum to improve a smile is an elective, cosmetic decision. Removing gum tissue because it is inflamed, infected or overgrown from periodontal treatment / gum disease is a health treatment with a different aim.

The two can look superficially similar on the day, but the reasoning, the urgency and the aftercare differ. A reputable clinic will not reshape gums cosmetically until any active inflammation, dental plaque and tartar build-up or pockets have been assessed and stabilised first.

Throughout this guide we keep that line clear: cosmetic gum contouring is about proportion and symmetry on a healthy mouth, never a shortcut past untreated gum problems.

Because the smile line is shaped by gums, teeth, lip and bone together, a gummy smile can have very different roots — and the cause decides the cure. Four patterns account for the great majority of cases, and many patients have a blend of two or more.

The first is altered passive eruption. As teeth come through in childhood, the gum is meant to migrate up the crown and settle near the point where enamel meets root, exposing the full tooth. When that migration falls short, the gum stays low and covers part of the crown. The teeth are a normal length but look short and stubby, with extra gum on show.

This is one of the most common and most treatable causes, because reshaping the gum (and sometimes a little bone) reveals tooth that is already there. Healthy tooth enamel usually sits just beneath that excess gum, waiting to be uncovered.

The second is vertical maxillary excess: the upper jaw has grown longer than average, so the whole tooth-and-gum block sits lower in the face and more gum shows when you smile. Here the issue is skeletal rather than gum-deep, and the gums themselves may be perfectly positioned on the teeth. Trimming gum will not fix a jaw that is simply too long, which is why diagnosis is so important.

The third is a hyperactive or short upper lip. Some lips lift unusually high when smiling, or are naturally short, so even normal gums are exposed at full smile. The teeth and gums can be textbook-perfect and the smile still reads as gummy purely because of how far the lip travels. This soft-tissue cause responds to lip-based treatments rather than gum surgery.

The fourth pattern is short or worn-down teeth. Years of grinding, acid erosion or simple wear can shorten the crowns, so the gum-to-tooth ratio shifts and more pink shows relative to white. Sometimes the gum has also crept down.

Restoring tooth length with dental bonding, dental crowns or veneers can rebalance the smile, occasionally alongside a touch of gum reshaping. Bite problems and certain types of malocclusion can drive this wear pattern, so the cause may sit upstream of the gums entirely.

Identifying which of these four is in play — or in what combination — is the single most important step, and it is why an honest clinic spends more time on diagnosis than on selling a procedure.

Once the cause is clear, the treatment almost chooses itself. The same amount of visible gum can be addressed by very different procedures depending on what is driving it, so this section walks through the main options and which problem each one solves.

Gum contouring (gingivectomy / gingivoplasty) is the workhorse for gum-level causes. A periodontist or dentist trims and reshapes excess gum tissue to create a higher, more even gum line and reveal more of each tooth. According to Cleveland Clinic, gum contouring removes excess tissue and reshapes the gum line to treat a gummy smile or an uneven margin.

It suits altered passive eruption and minor asymmetries beautifully, and results are typically lasting where the gum sits over healthy enamel.

When the bone crest is too high as well as the gum, simple trimming is not enough and the answer is surgical crown lengthening. Here the surgeon lifts the gum, removes a small amount of bone to give the right distance between bone and the new gum margin (protecting the "biological width"), then settles the gum lower on the tooth.

This exposes more tooth structure stably and is essential when a tooth also needs a crown or veneer and there is too little tooth showing to grip. It is more involved than contouring and needs a few weeks for the margin to mature before final restorations.

For a hyperactive or short lip, gum surgery is the wrong tool. Lip repositioning surgery shortens the reach of the upper lip so it covers more gum at full smile, by removing a strip of tissue inside the lip and re-securing it lower.

Alternatively, Botox for a hyperactive lip relaxes the muscles that hoist the lip, softening the lift; it is non-surgical and reversible but temporary, usually lasting around three to four months before a top-up is needed.

Where the root cause is skeletal — true vertical maxillary excess — gum and lip work only camouflage the issue. The definitive corrections are orthodontics, often with clear aligners to intrude over-erupted front teeth, or in pronounced cases jaw surgery to reposition the upper jaw.

These are bigger commitments reserved for marked cases, and not everyone with a skeletal tendency needs them. Finally, when short or worn teeth are the problem, length is rebuilt with bonding, crowns or porcelain veneers — sometimes after a little contouring to set the gum frame first. The art is choosing the least invasive option that genuinely fixes the underlying cause.

If your plan involves trimming gum, you will likely be offered the choice between a traditional scalpel approach and a laser. Both are routine, and a good operator gets excellent results either way; the differences are mostly in bleeding, stitches and recovery comfort.

With a scalpel gingivectomy, the surgeon marks the planned new gum line, numbs the area thoroughly, then removes and reshapes the excess tissue with fine blades. Stitches may be placed to control bleeding and guide healing. It gives the surgeon very direct tactile control of the new contour, which can be an advantage on complex reshaping or where bone is being adjusted at the same time.

Laser gingivectomy uses a focused light beam to remove tissue. Because the laser cauterises as it works, bleeding is usually minimal and stitches are often unnecessary, which many patients find makes the day and the first 48 hours more comfortable. Cleveland Clinic notes that because lasers seal tissue as they cut, you may not need stitches and recovery is often quick.

The trade-off is that lasers are best suited to soft-tissue reshaping; if meaningful bone needs removing for crown lengthening, a surgical flap and instruments are still required. Neither tool is universally "better" — the right choice depends on how much tissue is moving, whether bone is involved, and the surgeon's experience.

On the day, expect a thorough numbing with local anaesthetic so the procedure itself is not painful, though you will feel pressure and movement. Pure soft-tissue contouring of a few front teeth is often done in a single visit of thirty to sixty minutes. Surgical crown lengthening takes longer and is more involved.

Your clinician will usually photograph and measure your smile first, sometimes with a trial mock-up so you can preview the new proportions before anything is removed — a sensible safeguard, since gum that has been taken away cannot simply be put back.

Good candidacy is part of the safety story. Cleveland Clinic stresses that you should be in good oral health before contouring, with no untreated cavities or periodontal treatment / gum disease needing attention first. The American Academy of Periodontology similarly frames healthy gums as the foundation for any cosmetic gum work.

Heavy smoking, poorly controlled diabetes or active inflammation all slow healing and may need addressing before surgery. This is exactly why we separate elective contouring from disease management: reshaping gum over an unstable foundation invites relapse, gum recession or disappointment.

Recovery from cosmetic gum contouring is usually milder than people fear. After soft-tissue reshaping, most patients are comfortable on over-the-counter pain relief and back to normal routines within a day or two, with the gum margins tender for several days. Cleveland Clinic describes a typical gingivectomy recovery of about a week.

Surgical crown lengthening that involves bone takes longer to settle — the visible swelling eases within a week or two, but the gum margin keeps maturing for several weeks to a few months, which is why final crowns or veneers are placed only once that line is stable.

Aftercare is straightforward but matters. Expect to eat soft foods at first, avoid disturbing the area, rinse gently as instructed and keep up meticulous but careful cleaning so plaque does not irritate healing tissue. Your clinic may recommend a gentle antiseptic rinse and will review the site.

Sticking to a calm oral-hygiene routine — and a professional deep cleaning / scaling and root planing beforehand if there was any tartar — protects the result.

On durability, honesty is important and we avoid promises. Where gum was reshaped over healthy enamel and bone, results tend to be long-lasting and many patients are delighted years later. But gums are living tissue: outcomes depend on your healing, your home care and the original cause.

Treatments aimed at the lip behave differently — lip repositioning can be long-lasting, while Botox for a hyperactive lip is temporary by design and needs repeating. No ethical clinic can guarantee a permanent or risk-free result, and you should be cautious of any that does.

The risks are generally low in trained hands but real. They include temporary sensitivity as more tooth is exposed, gum tenderness and minor bleeding, and — the one to take seriously — removing too much tissue, which can leave teeth looking long, expose root surfaces or trigger gum recession that is hard to reverse. Asymmetry, slow healing or, rarely, infection are also possible.

This is why conservative planning, accurate measurement of bone and gum, and an experienced periodontist matter far more than the marketing around any one technique. If a tooth root becomes exposed, options such as gum grafting exist but add complexity — far better to remove the right amount the first time.

When weighing a clinic, prioritise diagnostic care and realistic expectations over the lowest quoted price.

Many patients consider Turkey because the combined cost of gum work and any restorations can be markedly lower than in the UK, US or Western Europe, while clinics there handle high volumes of cosmetic and Hollywood smile cases. We share only indicative ranges here, because the real figure depends on how many teeth are treated, whether bone is involved, and what restorations follow.

As a rough guide, cosmetic contouring or laser gingivectomy across the upper front teeth is typically the most affordable element, often a few hundred euros or pounds. Surgical crown lengthening with bone work costs more per area because it is more involved. Lip repositioning and Botox are separate line items, the latter recurring.

When gum work is the curtain-raiser to veneers or crowns, those restorations usually dominate the bill — see our notes on the cost of veneers in Turkey and overall Hollywood smile cost for context. Treat any headline number you see online as a starting point only.

The single reliable figure is a written itemised quote from your chosen clinic, listing each procedure, the materials, the number of teeth, follow-ups and what happens if revision is needed.

On timeline, simple soft-tissue contouring can often be done early in a trip, leaving healthy gums to settle before any same-visit cosmetic work. Where crown lengthening with bone is needed before veneers or dental crowns, the smarter plan is staged: gum surgery first, then a healing window of several weeks to a few months, then final restorations on a return visit.

Compressing that maturation to fit one short holiday is a common pressure and a poor idea — placing definitive restorations on a gum line that has not settled risks an uneven margin later. Ask any clinic to be explicit about staging and how a second visit, if needed, is handled.

Finally, see gum work as one instrument in a larger composition rather than a standalone fix. The most natural results come from designing the smile as a whole: gum line, tooth length and shape, colour from teeth whitening, and where relevant alignment through clear aligners — all planned together.

Deciding how many veneers you actually need, or whether veneers vs crowns suits your case, is far easier once the gum frame is right. Reshaping gum so teeth look longer can sometimes reduce how much restorative work you need at all.

A clinic that starts with diagnosis and a full smile-design plan — not a single procedure — is the one most likely to give you a result you are happy to live with.
