A confident smile can transform how a person feels day to day, but for some, showing too much gum when smiling can affect that confidence. Often referred to as a “gummy smile”, this common concern is something many patients seek advice on, particularly in a city like London where high-quality cosmetic and periodontal care is readily available.
At Pure Periodontics in the City of London, Specialist Periodontist Dr Gajen Raveendran brings extensive specialist experience in managing gum aesthetics, combining advanced clinical expertise with a thoughtful, patient-focused approach to treatment.
In this guide, the team explains what causes a gummy smile, the treatment options available, and how modern techniques can deliver natural, balanced results.
WHAT IS A GUMMY SMILE?
A gummy smile, clinically known as excessive gingival display, occurs when a significant portion of the gums are visible above the upper teeth when smiling. While there is no strict definition, many clinicians consider more than 3-4mm of visible gum tissue to fall into this category.
It is important to understand that a gummy smile is not necessarily a health problem. However, it can be a cosmetic concern for patients who feel their teeth appear too short or their smile looks unbalanced.
WHAT CAUSES A GUMMY SMILE?
There are several reasons why a gummy smile may occur, and identifying the underlying cause is key to choosing the most appropriate treatment.
- EXCESS GUM TISSUE
Some patients naturally have more gum tissue covering their teeth, making the teeth appear smaller than they actually are. - ALTERED TOOTH ERUPTION
In some cases, teeth do not fully emerge through the gums during development, leaving them partially covered. - LIP MOVEMENT
A hyperactive upper lip can lift higher than average when smiling, exposing more gum tissue. - JAW POSITIONING
The way the upper jaw develops can influence how much gum shows when smiling.
At Pure Periodontics, a detailed clinical assessment is carried out to determine the exact cause before any treatment is recommended. This ensures results that are both predictable and tailored to the individual.
GUMMY SMILE TREATMENT OPTIONS
Treatment for a gummy smile varies depending on the cause and severity. In many cases, a minimally invasive approach can achieve excellent results without the need for complex procedures.
LASER GUM CONTOURING / RESHAPING
One of the most effective and commonly recommended treatments is laser gum contouring.
Using advanced Waterlase™ technology, the team can gently remove excess gum tissue and reshape the gum line with exceptional precision. This allows more of the natural tooth structure to be revealed, creating a more balanced and aesthetically pleasing smile.
This approach offers several key benefits:
- Minimally invasive treatment with little to no discomfort
- Reduced need for anaesthetic in many cases
- Minimal bleeding during the procedure
- Faster healing compared to traditional methods
Pure Periodontics is one of the few practices in London using Waterlase™ laser technology. This enables highly controlled treatment while prioritising patient comfort and recovery.
WHAT TO EXPECT DURING TREATMENT
- CONSULTATION AND SMILE ASSESSMENT
The journey begins with a detailed consultation. The clinician will assess gum levels, tooth proportions, and smile dynamics. Photographs and measurements may be taken to plan treatment precisely. - PERSONALISED TREATMENT PLANNING
Based on the findings, a tailored plan is created. For many patients, laser gum contouring alone is sufficient to achieve the desired result. - THE PROCEDURE
During treatment, the Waterlase™ laser is used to carefully reshape the gum line. The process is typically quick, and many patients are surprised by how comfortable it feels. - AFTERCARE AND HEALING
Recovery is usually straightforward. Patients can return to normal daily activities quickly, with only minor sensitivity in the treated area.
WHY SPECIALIST CARE MATTERS
Gum contouring may sound straightforward, but achieving natural-looking results requires a deep understanding of both aesthetics and periodontal health.
As a specialist periodontist, Dr Gajen Raveendran has extensive experience in managing the delicate balance between gum health and cosmetic outcomes. This is particularly important when reshaping gum tissue, as the goal is not only to improve appearance but also to maintain long-term stability.
IS GUMMY SMILE TREATMENT RIGHT FOR EVERYONE?
Not every gummy smile requires treatment, and not every patient will benefit from the same approach.
Some key considerations include:
- The underlying cause of the gummy smile
- The overall health of the gums
- Patient expectations and desired outcome
A thorough consultation helps determine whether treatment is appropriate and what results can realistically be achieved.
HOW LONG DO RESULTS LAST?
Results from laser gum contouring are typically long-lasting. Once excess gum tissue is removed and the gum line is reshaped, it does not usually grow back.
Maintaining good oral hygiene and attending regular dental visits will help ensure the health and stability of the gums over time.
THE BENEFITS OF ADDRESSING A GUMMY SMILE
For many patients, the benefits go beyond aesthetics. A more balanced smile can:
- Improve overall facial harmony
- Boost confidence in social and professional settings
- Make teeth easier to clean by exposing more surface area
Importantly, treatment is often simpler than patients expect, particularly with modern laser technology.
