A smile can show more gum than you would prefer even when your teeth are healthy, clean and well aligned. Gum contouring for a gummy smile may improve the balance between teeth and gum tissue, but it is not a one-size-fits-all cosmetic treatment. The right approach depends on why your gums are prominent, the shape of your teeth, your bite and the amount of gum and bone supporting each tooth.
For some people, carefully reshaping excess gum tissue creates a more even, tooth-focused smile. For others, gum contouring alone would not address the underlying cause. A considered assessment is the best place to start, particularly when you are planning veneers, crowns or a broader smile design.
What is gum contouring for a gummy smile?
Gum contouring, also called gum reshaping or gingival recontouring, is a dental procedure used to refine the height and shape of the gumline. The aim is usually to reveal more of the visible tooth surface, improve left-to-right symmetry or create a more proportionate frame around the teeth.
A gummy smile is a broad description rather than a diagnosis. It generally refers to a smile where a noticeable amount of upper gum is visible when laughing or smiling. While there is nothing unhealthy about showing gum, some people feel that it draws attention away from their teeth or makes their teeth look shorter than they are.
Where excess gum tissue is covering part of otherwise healthy teeth, contouring can make a meaningful visual difference. The treatment is planned in millimetres, not broad strokes. Even small changes to the gumline can affect tooth proportions, smile symmetry and the way future cosmetic work sits alongside natural teeth.
Why does a gummy smile happen?
The cause matters because it determines whether gum contouring is likely to be worthwhile. A prominent gum display may result from altered passive eruption, where the gums have not receded to their typical position after the teeth erupted. In these cases, the teeth can appear short because more enamel is covered than expected.
Other causes are less suited to gum contouring alone. A short or highly active upper lip can lift higher when you smile, revealing more gum. Jaw position can also play a role, particularly where the upper jaw sits more prominently in the face. In addition, naturally short teeth, tooth wear, gum enlargement caused by inflammation or medication, and an uneven gumline can each create a different visual concern.
This is why a photograph alone cannot confirm the right treatment. A dental examination considers your gum health, the position of the bone around the teeth, tooth length, lip movement and bite. Digital scans and smile planning can help show how proposed changes may affect the overall result before treatment begins.
When gum contouring may be suitable
Gum contouring may be considered when your gums are healthy and there is excess soft tissue covering part of the tooth surface, or when the gumline is uneven around the upper front teeth. It can also be used as part of a wider cosmetic plan where the gumline needs to be balanced before porcelain veneers or crowns are designed.
The best candidates usually have realistic goals. Gum reshaping can refine the frame of a smile, but it cannot change the position of the jaw or completely alter how the upper lip moves. If the main concern is lip movement or jaw position, another treatment approach may be more appropriate.
A clinician will also check whether there is adequate space between the proposed new gumline and the underlying bone. This relationship is important for long-term gum health. If the gum is removed without considering the supporting bone, the tissue may grow back, look uneven or become difficult to maintain. In some situations, a procedure known as crown lengthening may be recommended to adjust both gum and bone levels conservatively.
How the treatment is planned and performed
A consultation-led plan should begin with your concerns: perhaps your teeth look too short in photos, your gumline is uneven, or you want a more harmonious result before veneers. Your dentist will assess your teeth, gums and bite, and may use intraoral scanning and clinical photographs to plan proportions carefully.
Before treatment, the gums need to be healthy. If there is bleeding, swelling or active gum disease, this should be addressed first. Reshaping inflamed tissue can compromise healing and make it difficult to judge the true gumline.
During the procedure, local anaesthetic is commonly used to keep you comfortable. The dentist reshapes the gum tissue with an appropriate surgical technique. Where indicated, crown lengthening involves more detailed work to establish a stable gum position in relation to the bone. The procedure time varies according to how many teeth are being treated and whether bone adjustment is required.
The objective is not to make every gum margin identical. Natural teeth have subtle differences in shape and position. Good cosmetic planning aims for balance that looks believable in your face, rather than a smile that appears over-treated.
Recovery, comfort and aftercare
Most people experience tenderness and mild swelling after gum contouring, particularly during the first few days. The level of discomfort depends on the extent of treatment and whether bone was adjusted. Your dentist may recommend pain relief, a gentle cleaning routine and temporary dietary changes while the area settles.
Soft foods can be more comfortable initially, and it is sensible to avoid brushing aggressively around the treated gums. Follow the specific aftercare advice provided for your procedure, including any recommendations for rinses, review appointments and returning to normal oral hygiene.
The gums may look different as they heal. Early swelling can make it difficult to judge the final contour immediately, and tissue maturation takes time. If veneers or crowns are planned after gum treatment, allowing the gums to stabilise is often important before final restorations are made. Your dentist can advise on an appropriate timeline based on the procedure performed and your healing response.
Risks and limitations to understand
Like any dental procedure, gum contouring carries risks and limitations. These can include post-treatment sensitivity, bleeding, swelling, infection, uneven healing, gum recession or changes in the final gum position. Where teeth are reshaped or restored as part of a broader cosmetic plan, there may also be risks associated with those separate procedures, including future repair or replacement requirements.
Results are influenced by anatomy, oral hygiene, gum health and the amount of treatment required. Gum tissue can regrow in some circumstances, while recession may make a tooth look longer than intended. This does not mean treatment is unsuitable, but it does mean the decision should be based on a clear understanding of what is achievable and what maintenance may be needed.
People who clench or grind their teeth may also need bite assessment and, in some cases, an occlusal splint to help protect teeth and cosmetic restorations. A balanced smile should function well as well as look considered.
Combining gum contouring with veneers or smile design
Gum contouring can be valuable before porcelain veneers when the concern involves both tooth shape and gum proportions. For example, gum reshaping may reveal more natural tooth structure, while veneers can address colour, chips, wear, spacing or shape. Treating only one element may leave the overall smile feeling unfinished.
That said, veneers are not automatically required after gum contouring. If the underlying teeth have pleasing colour, shape and condition once more tooth surface is revealed, gum contouring alone may be enough. Conversely, where teeth are naturally small, worn or heavily restored, a combined plan may offer more control over the final proportions.
At SmileOn Perth, digital planning can support this decision-making process by translating your goals into a structured clinical plan. The most appropriate treatment is the least invasive option that can reasonably address your concerns while protecting long-term oral health.
Choosing your next step
If a gummy smile affects how freely you smile in photographs, at work or in social situations, start with an assessment rather than assuming a particular procedure is the answer. Ask what is causing the gum display, whether gum contouring alone is suitable, how healing may affect your timeline and what risks apply in your case.
A well-planned result is not about removing as much gum as possible. It is about creating proportions that feel natural to you, respect the health of your teeth and gums, and give you a smile you can feel comfortable showing.
