Gum Correction

Why gum correction matters

A smile is not just teeth. The gums frame them, and if the frame is wrong the picture never looks right no matter how good the teeth are. Patients often arrive convinced their teeth are too short or unevenly sized, when the teeth are perfectly normal and it is the gum line sitting too low or at inconsistent heights.

That distinction matters commercially as well as clinically, because the alternative most people are offered is veneers. Reshaping the gum line achieves the same visual result by removing nothing from healthy teeth. Where the gum is the problem, treating the teeth is both more invasive and less effective.

What is gum correction?

Gum correction, gum contouring and gum line correction all describe reshaping the soft tissue around the teeth to improve proportion, symmetry and health. It can mean removing excess tissue where the gum covers too much of the tooth, adding tissue where recession has exposed too much, or evening out a line that sits at different heights across the smile.

It is not purely cosmetic. Recession exposes root surfaces, which are softer than enamel, more prone to decay and often sensitive. Excess tissue creates spaces that are hard to clean and invite inflammation. Correcting the gum line frequently improves both appearance and long-term health at once.

Who is it suitable for?

Patients with a gummy smile, where too much gum shows when smiling. Patients whose gum line is uneven, so teeth appear different lengths. Patients with recession, where roots are exposed and teeth look increasingly long. Patients with excessive gum growth, sometimes caused by medication. And patients with discoloured gum tissue.

What matters first is gum health. Contouring inflamed or infected gums is pointless and will not hold, so if there is active gum disease we treat that first and reassess. That is not a delaying tactic, it is the difference between a result that lasts and one that relapses.

Treatment options

Gum line correction and contouring

Reshaping the gum margin so it sits at the right height and follows a consistent line across the smile. Small changes here produce disproportionate improvements in how the teeth look.

Gummy smile treatment

Where too much gum shows when you smile. The right treatment depends entirely on the cause, which may be the gum position, the way the lip moves, the bone level, or the teeth themselves not having fully erupted. Diagnosing that correctly is what separates a good result from a disappointing one.

Laser gum contouring

Where suitable, a laser allows precise reshaping with minimal bleeding and a comfortable recovery.

Gum grafting

Where recession has exposed root surfaces, tissue is grafted to cover them, protecting the root and restoring the proportion of the tooth.

Excessive gum growth correction

Overgrown tissue, sometimes a side effect of medication, is reduced so the teeth are visible and the area can be cleaned properly.

Discoloured gum treatment

Addressing pigmentation or discolouration in the gum tissue itself.

The process

We start by assessing your gum health, the bone level beneath, your lip position and your teeth together, because a gummy smile caused by lip movement needs a different answer to one caused by gum position, and treating the wrong cause achieves nothing. The plan is discussed and agreed before anything begins.

Treatment itself typically takes around 90 minutes under local anaesthetic. Recovery is usually around five days, with some tenderness in the first few. You will have clear aftercare instructions and a review appointment to check healing.

Our approach

Gum correction sits at the point where periodontal health and cosmetic dentistry meet, which is exactly why it is so often done badly. Treated as a purely cosmetic trim it relapses; treated as a health problem alone it never looks right. Prof Dr Christian Mehl, a registered specialist in prosthodontics, plans these cases with the final appearance in mind and the underlying health treated first. Where a case calls for a registered periodontist, we refer.

I honestly cannot recommend Professor Christian Mehl and his wonderful team at Wimpole Street Dental Clinic highly enough! The standard of expertise and professionalism is absolutely exceptional, but what really makes this practice so special is the genuine kindness, care and personal attention you receive. There's something rather wonderful and almost old-fashioned about the way they look after you. You feel genuinely cared for as an individual, never just another patient. Dr Mehl and his team have gone above and beyond for me, particularly when I really needed their help, and I cannot express how grateful I am. Choosing this practice has been one of the very best decisions I've made for my dental health. An absolutely exceptional team of people, and I couldn't recommend them more wholeheartedly! Thank you!

Phenomenal clinic. I'm a very particular patient and take great care in choosing a dentist, so I don't give praise lightly. The Wimpole Street Dental Clinic has exceeded my expectations on every count. The specialists are highly skilled and clearly at the top of their field, yet completely approachable. They explain everything as the procedure is happening, so you always know what's being done and why. That makes a real difference to how relaxed you feel in the chair. The front desk team were amazing too: warm, efficient and genuinely helpful. It's rare to find this level of expertise combined with such attentive patient care. Thank you to the whole team. Highly recommended.

I cannot recommend this dental practice highly enough. Professor Mehl has provided an exceptional standard of care and professionalism, and I have been genuinely impressed by both his expertise and his approach to patient care. He is exceptionally kind, patient and reassuring, and completely non-judgemental. I have never felt embarrassed or uncomfortable discussing my dental hygiene, and he has always made me feel at ease. His positive and compassionate manner immediately puts you at ease, even if you are someone who feels anxious about dental treatment. What I particularly appreciate is the personal level of care he provides. He remembers me personally, greets me when I arrive and genuinely takes an interest in me as a patient. This makes such a difference and is something I have rarely experienced elsewhere. I am currently saving towards an implant, and Professor Mehl went above and beyond by building a temporary tooth. I was incredibly touched by this gesture and it is a wonderful example of the kindness and consideration he shows his patients. He is also exceptionally skilled, even the injections were completely painless, which is something I have never experienced with another dentist! I would also like to mention Jennifer (dental therapist) who is absolutely wonderful. She gave me an incredibly thorough deep clean, yet somehow managed to make the entire experience completely comfortable and pain-free. She did an exceptional job, and I was so impressed with the care and attention to detail she showed throughout. Jennifer is also incredibly warm and personable, her smile genuinely brightens the room. Like Professor Mehl, she remembers me personally, which makes every visit feel welcoming and reassuring rather than clinical. I am extremely grateful for the care I have received from the whole team. Professor Mehl and Jennifer combine exceptional professionalism and expertise with genuine kindness and compassion. It is clear that they truly care about their patients, and I would wholeheartedly recommend this practice to anyone looking for outstanding dental care.

I was on vacation in London, and a crown came off during my first full day there. I was literally 4,000 miles from home, and, as luck would have it, I was near the Wimpole Street Dental Clinic. The receptionist could see the panic on my face when I walked through the door. He calmed me down by assuring me that he would make sure I got fixed up right away. Soon after, I saw the dentist. He was excellent. Fixed me up in no time. I was able to enjoy the rest of my bucket-list trip without worrying about my teeth! I can't thank them enough! If you have dental needs, I highly recommend stopping in! Here's a pic of me with the doc and his staff after they fixed my crown—such a great group of people.

Really friendly dentist. My daughter needed some fillings and we’re really pleased with the results - they are invisible and it wasn’t painful

FAQs

Common questions about gum correction, answered clearly and honestly.

Contact us
How much does gum correction cost?
The cost depends on which technique your case needs and how many teeth are involved. Because the right approach varies so much with the cause, your cost is confirmed at consultation once we have assessed your gums, bone level and lip position. A new patient consultation is £240.
Is gum correction painful?
It is carried out under local anaesthetic, so you should feel nothing during treatment. Expect some tenderness for the first few days, with recovery usually around five days. Laser contouring, where suitable, tends to be the most comfortable option.
Will my gums grow back?
Properly performed contouring is generally stable, and grafted tissue integrates permanently. What causes relapse is treating the symptom rather than the cause, or contouring gums that were inflamed to begin with. That is why we treat any active gum disease first and reassess.
Can gum correction fix a gummy smile on its own?
Sometimes, but not always, and the honest answer depends on the cause. A gummy smile can come from gum position, lip movement, bone level or teeth that have not fully erupted. Where the cause is not the gum, gum surgery alone will disappoint. Diagnosing it correctly is the whole job.
Do I need veneers as well?
Often not, which is the point. Patients frequently arrive believing their teeth are too short when the teeth are entirely normal and the gum line is low. Reshaping the gum achieves the result without removing anything from healthy teeth. If you have been quoted for veneers to fix short-looking teeth, it is worth a second opinion.
Is it just cosmetic?
No. Recession exposes root surfaces that are softer, more decay-prone and often sensitive. Excess tissue creates spaces that are difficult to clean and encourage inflammation. Correcting the gum line usually improves health and appearance together.
How long does it take?
Around 90 minutes for most cases, in a single appointment, with roughly five days of recovery. Grafting cases may need longer to heal fully, and you will have a review appointment to check progress.
