Gummy Smiles Are Usually Fixed With Gum Contouring or Lip Repositioning

A gummy smile happens when more gum tissue than usual shows above your top teeth when you smile. It’s a common concern that research suggests affects a meaningful share of adults, more often women than men and thankfully, gummy smile treatment options in London are more straightforward than most people expect.

What Counts as a Gummy Smile?

Dental professionals generally describe a smile as “gummy” when more than 3mm of gum tissue is visible above the upper teeth. According to research published via the National Library of Medicine, excessive gingival display affects a meaningful share of the population, with the condition more common in women and most noticeable in younger adults.

It’s worth saying clearly: a gummy smile isn’t a health problem on its own. Gummy smiles treatment is almost always sought for appearance rather than any medical need, and that’s a perfectly reasonable reason to look into it.

What Causes a Gummy Smile?

Before deciding on gummy smile treatment, it helps to understand why the gums are showing more than expected. A few common causes include:

• Teeth that appear small compared to the surrounding gum tissue.
• An upper lip that lifts higher than average when smiling.
• Teeth that haven’t fully emerged from under the gum.
• Gum tissue that’s grown to cover more of the tooth than it should.
• The upper jaw sitting slightly further forward or lower than typical.

Because these causes are different, the right gummy smile treatment in London depends on which one applies to you. This is usually worked out during a consultation, often alongside an X-ray to check how the jaw and teeth line up beneath the surface.

Gum Contouring: The Most Common Fix

For many patients, gummy smile treatment starts with gum contouring, also called gingival recontouring. This is a straightforward procedure where a dentist reshapes the gum line by removing a small amount of tissue, exposing more of the natural tooth underneath.

At Smile Cliniq, which offers this treatment at its Finchley practice, gum contouring is carried out under local anaesthetic and usually completed in a single visit. A soft tissue laser or a fine surgical tool is used to reshape the gum line, and most patients experience only mild sensitivity for a couple of days afterwards.

This option works well when the main issue is extra gum tissue covering otherwise healthy teeth, rather than a problem with the lip or jaw.

Lip Repositioning: A Different Approach

When the cause is a lip that lifts too high, gum contouring alone won’t solve the problem, since the gum tissue itself may be a normal amount. In these cases, lip repositioning is often the better fit.

This procedure limits how far the upper lip can rise when you smile by adjusting the muscle attachment inside the lip. A study published in the Journal of Indian Society of Periodontology found lip repositioning to be an effective option for correcting a gummy smile caused specifically by a hypermobile upper lip, with results holding up well over follow-up periods.

Gummy smile treatment in London involving lip repositioning is done under local anaesthetic too, and recovery is generally quick compared with more involved jaw surgery.

When Jaw Surgery Might Be Needed

In more pronounced cases, where the upper jaw itself sits too low, gum contouring or lip repositioning may not be enough on their own. Here, a dentist may refer you to an oral surgeon, who can assess whether orthodontic treatment or jaw surgery is a better route.

This is a bigger step than the softer tissue options above, and it’s usually reserved for cases where the jaw position is the main driver behind the gummy smile, rather than gum tissue or lip movement.

What About Injections?

Some patients look at injectable treatments as an alternative to surgery. These work by temporarily relaxing the muscle that lifts the upper lip, reducing how much gum shows when smiling. The effect generally lasts a few months before wearing off, which makes it a reasonable option for people who want to trial the look before committing to something permanent.

Choosing the Right Option

Because gummy smile treatment varies so much depending on the cause, a proper assessment matters more than picking a treatment off a list. A dentist will usually look at:

• How much gum tissue is visible when you smile
• Whether the upper lip is contributing to the display
• The position and shape of your upper jaw
• Your own priorities around downtime and how permanent you want the result to be

Getting this assessment right from the start avoids paying for treatment that doesn’t address the actual cause.

Final Thoughts

Gummy smile treatment in London usually comes down to gum contouring or lip repositioning, with jaw surgery reserved for cases where the jaw itself is the underlying cause. Both of the more common options are done under local anaesthetic, often in a single visit, with a short recovery period. If you’re self-conscious about how much gum shows in your smile, a proper assessment is the best starting point, since it identifies the actual cause rather than assuming one treatment fits everyone.
