Gummy Smile Treatment

A gummy smile is simply a smile in which more gum tissue than average shows above the upper teeth. It is a variation, not a disease — many people are entirely happy with theirs. But if the amount of gum on display makes you self-conscious, gummy smile treatment in London can help rebalance the proportions between lip, gum and teeth. At our Wimpole Street practice, the starting point is always identifying the cause, because the cause determines the treatment.

There are several recognised patterns. In some people, the teeth erupted with gum covering more of the crown than usual (altered passive eruption), making healthy teeth look short. In others, the upper lip is short or lifts strongly when smiling. Some cases involve vertical growth of the upper jaw, and others follow tooth wear, where teeth shorten and gum display increases in proportion. Often, more than one factor contributes.

Treatment tends to suit adults whose gum display genuinely bothers them and who have healthy gums to begin with. It is worth saying plainly: up to a few millimetres of gum display is generally considered within the normal, attractive range, and we will tell you if we think intervention offers little benefit. Suitability, and the likely cause in your case, is confirmed at an in-person consultation with a GDC-registered dentist.

Assessment involves examining how your lip moves at rest and in a full smile, measuring the visible tooth height against typical crown proportions, checking gum health, and taking photographs and, where useful, X-rays to see where the bone sits relative to the gum margin. From these findings we can usually pinpoint which of the causes applies to you — and therefore which treatments are realistic.

Where the gum covers too much of the tooth, gum contouring can reshape the margin to reveal the natural crown length. Where the supporting bone sits close to the margin, crown lengthening — a minor surgical procedure adjusting both gum and bone — gives a more stable result. Where the teeth are short through wear, restorative treatment such as bonding or veneers rebuilds proportion instead of removing tissue.

Where a strong lip lift is the dominant factor, dental procedures alone may not achieve what you want. In those cases we discuss a referral for botulinum toxin treatment to soften the lip elevation — a temporary, repeatable option provided by an appropriately trained prescriber — or, rarely, surgical options managed by specialist colleagues. Being honest about which route fits your anatomy avoids disappointment and unnecessary treatment.

Because the right plan is so case-specific, gummy smile treatment is quoted after consultation, with every option and its cost explained in writing as an itemised quote. Cost drivers include the number of teeth involved, whether soft tissue alone or bone also needs adjusting, whether restorative work forms part of the plan, and whether any element is provided by referral.

Every option has limitations. Contouring and crown lengthening involve a healing period and carry small risks of sensitivity or minor asymmetry that may need refinement. Botulinum toxin effects are temporary, typically lasting a few months, and require repeat treatment. Restorative options commit teeth to long-term maintenance. Individual results vary, and no outcome can be guaranteed — which is why we plan digitally and show you the intended change first.

Aftercare depends on the route chosen: gentle hygiene and a review after soft-tissue procedures, routine maintenance for restorative work, and scheduled top-ups if a muscle-relaxant referral forms part of your plan. Whatever the combination, ongoing check-ups keep the result healthy and stable.

It can help to understand how the causes are teased apart in practice. At consultation we ask you to smile naturally, then broadly, and we measure how far the lip travels between rest and full smile — a strong lift points towards the lip as the driver. We then measure the visible height of the upper front teeth: if they measure short but probing shows the full crown hiding beneath the gum, altered eruption is likely; if they are short because the biting edges have worn, restoration is the logical route. This step-by-step reasoning is why a single consultation on Wimpole Street can usually replace a lot of inconclusive online research.

Patients considering treatment often ask how natural the result will look, and the honest answer is that naturalness comes from restraint. The aim is never to eliminate gum display entirely — a smile with no visible gum can look as unusual as one with a great deal — but to bring the proportions of lip, gum and tooth into a range that reads as unremarkable. Digital planning helps here: seeing a simulated change of two millimetres versus four makes the conversation concrete, and many patients choose the more conservative option once they see both side by side.

If you decide not to proceed, nothing is lost. A gummy smile is a cosmetic variation, not a condition that deteriorates if untreated, and monitoring costs nothing. The exception is where tooth wear is driving the change — worn teeth may continue to shorten if the cause, such as grinding, is not addressed, so in those cases we may recommend protective measures like a night guard even if you defer the cosmetic element. Separating what is optional from what is advisable is part of an honest consultation.

Aftercare and maintenance depend on the chosen route, but the principles are consistent: gentle hygiene while soft tissue heals, scheduled reviews so we can confirm the margin has settled where planned, and routine check-ups thereafter. Where restorative work such as bonding or veneers forms part of the plan, those restorations carry their own maintenance needs — careful cleaning at the margins and, where grinding is present, a protective night guard. Many patients find the whole sequence less involved than expected: a small number of well-planned visits, each explained in advance, with written aftercare guidance to take home from our London practice.

We are easy to reach from across London: the practice is on Wimpole Street in Marylebone, within a short walk of Bond Street, Oxford Circus and Regent’s Park underground stations. Because gummy smile treatment often involves a planning visit, a treatment visit and a review, straightforward transport links make the sequence easy to fit around a working diary, and appointments can usually be grouped or spaced to suit your schedule rather than ours.

Patients travel to our Marylebone practice, near Harley Street, for gummy smile treatment because it sits at the junction of several disciplines — periodontal, restorative and facial. At our Wimpole Street practice in central London we can assess all the contributing factors in one visit, plan the combination that fits your anatomy, and coordinate any referrals ourselves, so you have a single, coherent plan rather than piecemeal treatment.
