A gummy smile is a cosmetic concern, not a disease, and in most cases it is safely correctable. When too much gum tissue shows above the upper teeth, or when gum levels are uneven, teeth look short and the smile looks unbalanced. Modern gum reshaping can correct this predictably, provided the cause has been identified first, because excessive gum display has several very different origins.
The clinical term for excessive gingival display is altered passive eruption when the gum has not receded fully during development, and vertical maxillary excess when the upper jaw itself is proportionally long.
Identifying which applies matters, because the treatment differs. Once gum levels are corrected, tooth proportions often still need refinement, and conservative porcelain veneers or bonding complete the visual balance.
If the underlying issue is jaw position or tooth eruption pattern, treatment through orthodontics may be required before or instead of soft tissue surgery.
Healthy gums are a precondition for any reshaping. Stable results depend on inflammation being controlled first through professional dental hygiene care and good home technique.
A planning consultation at Richmond Hill Smile Centre, one of the best dental clinics in Richmond Hill, begins with measurement and photographs rather than assumptions about what needs changing.
Anyone considering treatment should have the cause explained clearly, and an experienced dentist will always distinguish between a soft tissue issue, a skeletal issue, and simple tooth wear.
Direct Answer: What Is Gum Reshaping?
Gum reshaping, also called gingival contouring or gingivectomy when tissue is removed, is a procedure that alters the position and contour of the gum margin to improve tooth proportions and smile symmetry. It may involve removing excess soft tissue, and in some cases recontouring a small amount of underlying bone so the result remains stable.
Why Do Some People Show Too Much Gum?
Altered Passive Eruption
The gum tissue fails to migrate to its normal position as teeth erupt, leaving crowns partly covered. Teeth are normal length but look short.
Excessive Gingival Overgrowth
Certain medications, hormonal changes, poor plaque control, and some medical conditions can enlarge gum tissue.
Short Upper Lip or Hypermobile Lip
The lip lifts unusually high when smiling, exposing more gum. Soft tissue surgery on the gum may not be the appropriate solution here.
Vertical Maxillary Excess
A skeletal pattern in which the upper jaw is proportionally long. Significant cases may need orthodontic or surgical management rather than gum contouring alone.
Tooth Wear
Grinding shortens teeth over years, which increases the relative amount of gum on display even though gum position has not changed.
Uneven Gum Levels
Asymmetry between individual teeth, often noticeable on the canines or lateral incisors, can make an otherwise good smile look imbalanced.
Who Is a Suitable Candidate?
- Adults with healthy gums and no active periodontal disease
- Patients with adequate bone support and no significant recession
- Non-smokers, or those willing to stop, since smoking impairs healing
- People with realistic expectations about the extent of change
- Patients whose grinding, if present, is managed with a protective guard
- Those able to maintain excellent daily plaque control afterwards
Treatment is generally deferred where there is untreated decay, active gum inflammation, or an undiagnosed skeletal cause.
How the Procedure Works, Step by Step
- Assessment. Measuring gum display at rest and while smiling, checking tooth proportions, probing depths, and lip mobility.
- Imaging. Photographs and radiographs to evaluate bone level relative to the intended gum position.
- Planning. Marking the proposed new gum contour and confirming symmetry against facial reference lines.
- Local anaesthesia. The area is numbed thoroughly before treatment begins.
- Tissue recontouring. Excess gum is removed or reshaped using a scalpel, electrosurgery, or a dental laser depending on the case.
- Bone recontouring if required. Where bone sits too close to the intended margin, a small amount is adjusted so tissue does not rebound.
- Healing. Soft tissue settles over several weeks, with the final contour usually assessed after a few months.
- Restorative refinement. Bonding, veneers, or crowns if tooth shape still needs improving after healing.
Laser Versus Conventional Technique
- Dental laser: good haemostasis, often less bleeding and swelling, and generally comfortable healing. Best suited to soft tissue only cases.
- Conventional surgical technique: allows precise flap access and bone recontouring where required, which is essential for long-term stability in altered passive eruption.
- Electrosurgery: effective for tissue removal with controlled bleeding, though care is needed near restorations and implants.
Summary: lasers are excellent for straightforward soft tissue contouring, while cases involving bone need a conventional approach. The technique should follow the diagnosis rather than the marketing.
Recovery and Aftercare
- Expect mild soreness and tenderness for a few days, usually manageable with recommended pain relief.
- Eat soft, lukewarm foods for the first 48 hours and avoid spicy or acidic items.
- Avoid brushing directly over the treated margin initially, following the specific instructions given.
- Use any prescribed rinse exactly as directed.
- Avoid smoking and alcohol during early healing.
- Skip strenuous exercise for the first day or two to reduce bleeding risk.
- Attend the review appointment so healing and symmetry can be confirmed.
- Resume full brushing and interdental cleaning as soon as advised, since plaque control protects the result.
Risks and Honest Limitations
- Temporary sensitivity of newly exposed tooth surfaces
- Gum tissue rebound if bone level was not addressed when necessary
- Minor asymmetry requiring refinement
- Delayed healing in smokers or patients with poorly controlled diabetes
- Recession if too much tissue is removed or if there is inadequate bone support
- The result may not fully resolve gum display caused by a skeletal or lip factor
These points should be discussed before treatment. Gum surgery is an irreversible procedure on living tissue and should only be performed by licensed dental professionals after full assessment. The content here is general information rather than personal clinical advice.
Myths About Gum Contouring
Myth: It is purely cosmetic with no functional value
Correcting overgrown tissue improves access for cleaning and can reduce plaque retention, which benefits gum health as well as appearance.
Myth: The gums will simply grow back
Properly diagnosed and executed contouring, including bone adjustment where needed, gives stable results. Rebound usually indicates the underlying cause was not fully addressed.
Myth: It is extremely painful
The procedure is performed under local anaesthesia, and most patients describe the recovery as mild tenderness rather than significant pain.
Myth: Anyone with a gummy smile needs surgery
Sometimes the real issue is short teeth from wear, or a hypermobile lip. Treating the wrong cause produces disappointing results.
Myth: Results are immediate
Tissue continues to mature for weeks. Final restorative work is best delayed until contours have stabilised.
Protecting the Result Long Term
- Maintain meticulous daily plaque control at the gum margin
- Keep professional cleaning appointments at the interval advised
- Use a soft brush and non-abrasive toothpaste to avoid recession
- Wear a night guard if you grind, to prevent further tooth shortening
- Report any bleeding, swelling, or change in gum level promptly
- Avoid smoking, which impairs both healing and long-term gum stability
Discussing Your Options in Richmond Hill
Richmond Hill Smile Centre approaches gum reshaping as a diagnostic exercise first and a procedure second, which is why consultations include measurement, photographs, and a clear explanation of what is causing your gum display. Where the honest answer is that contouring alone will not achieve your goal, that is explained openly.
The clinic is located at 10157 Yonge St Unit 101, Richmond Hill, ON L4C 1T6, Canada, and enquiries can be sent to info@richmondhillsmilecentre.ca if you want to understand your options before committing. Patients who feel self-conscious about their smile are given time to ask questions without pressure.
Aftercare and review are built into the plan, because stable gum contours depend as much on healing and hygiene as on the procedure itself. Local, continuous care makes that follow-through straightforward.
Frequently Asked Questions
How long does gum reshaping take?
Treating a few front teeth often takes under an hour. More extensive cases involving bone recontouring take longer and may be staged across sessions.
Is the procedure permanent?
Results are generally long lasting when the diagnosis is correct and bone level is addressed where needed. Good plaque control and avoiding smoking protect the outcome.
Will my teeth be sensitive afterwards?
Some temporary sensitivity on newly exposed surfaces is common and usually settles within a few weeks. Desensitising toothpaste can help during that period.
Can gum contouring fix uneven gums caused by braces?
Often yes, once orthodontic treatment is complete and tissues have settled. Timing matters, so the assessment should happen after alignment is finished.
Do I need veneers as well?
Not always. If teeth are a healthy shape and colour, contouring alone may be enough. Veneers or bonding are added only when proportions still need refining.
Conclusion
Excessive or uneven gum display is common and usually correctable once the true cause is identified. Healthy gums, accurate planning, and attention to bone level are what make results stable rather than temporary. Start with a proper assessment so the treatment matches the diagnosis, not the assumption.
