Gum Contouring vs Crown Lengthening for a Gummy Smile: What Each Procedure Changes

Key Takeaways
- Gum contouring removes only soft tissue and works when the bone already sits well below the enamel edge; crown lengthening reshapes bone so a lower gum line can stay put permanently.
- Gum tends to re-form a fixed zone of attached tissue above bone, known as biologic width, which is why gum trimmed too close to bone often appears to grow back within months.
- Many gummy smiles are caused by a high-lifting upper lip or a long upper jaw, and neither gum contouring nor crown lengthening changes those causes.
- Surface healing after both procedures is usually measured in one to two weeks, but the gum margin after crown lengthening keeps settling for months, which is why final veneers or crowns are typically delayed.
- Bleeding, swollen gums are usually inflammation from plaque or gum disease rather than extra gum, and treating that first can reduce the gummy appearance without any surgery.
- A laser, scalpel or electrosurgery tip all remove the same tissue; the tool does not determine whether the result lasts, the distance to bone does.
Gum contouring (gingivectomy or gingivoplasty) reshapes only the soft gum tissue and suits a gummy smile caused by excess gum that covers normal teeth. Crown lengthening removes gum and, when needed, a small amount of underlying bone, so more tooth can be exposed permanently or a restoration can be placed. A periodontist or dentist chooses between them after measuring gum, bone and tooth position.
She had learned to smile with her lips closed. In photos from graduation, from her brother’s wedding, from a beach holiday, the same careful half-smile appears, because every full grin seemed to show more pink than white. When she finally asked a dentist about it, she expected one answer. Instead she got two procedure names, a mirror, a tiny ruler pressed gently against her gum, and an X-ray.
That small ruler is the heart of the gum contouring vs crown lengthening question. Both procedures aim at the same complaint, teeth that look short under a heavy band of gum, but they change different layers of the mouth. One trims tissue you can see. The other reshapes the bone you cannot.
This explainer walks through what each procedure actually does, who tends to be offered which, how the recovery differs, and the questions worth asking before anyone picks up an instrument. The decision stays with your treating team; the goal here is to make that conversation clearer.
Why does a gummy smile have more than one cause?
A “gummy smile” is the everyday term for a smile that shows a noticeably wide band of gum above the upper front teeth. Dentists call the visible gum above the teeth “gingival display.” What matters clinically is not the width itself but why it is there, because the cause points to the procedure.
Four mechanisms account for most cases. In the first, the teeth erupted normally but the gum never receded to its usual adult position; the crowns are full length under the tissue, simply covered. This is called altered passive eruption. In the second, the gum has swollen or overgrown, often in response to plaque, hormonal shifts, mouth breathing or certain medicines; treating the cause and reducing the tissue is the priority. In the third, the teeth and gum are normal but the upper lip lifts unusually high, or the lip is short. In the fourth, the upper jaw itself sits low relative to the face, so the whole tooth-and-gum complex is displayed.
Only the first two are gum problems. The third is a lip problem and the fourth is a skeletal one. This is why a good assessment starts with a resting-lip measurement, a full smile, a periodontal probe slipped gently between gum and tooth, and an X-ray to see where the bone ends. The probe reveals how deep the little groove around each tooth runs. The X-ray reveals whether the bone crest sits close to the enamel edge or well below it.
If the tooth is fully formed and the bone is low enough, removing gum alone works. If the bone hugs the enamel, cutting gum without touching bone invites the tissue to grow straight back. That single anatomical fact, explored further below, separates gum contouring from crown lengthening more than any marketing label does.
What does gum contouring actually change?
Gum contouring is an umbrella term for two related soft-tissue procedures. A gingivectomy removes a measured strip of gum. A gingivoplasty reshapes the remaining edge so it follows a gentle scallop from tooth to tooth. Neither touches bone.

The appointment typically begins with local anesthetic, the same numbing injection used for a filling. The clinician marks the planned new gum line, sometimes with tiny bleeding points made by the probe, checks it against the smile line and the position of the underlying bone, then removes tissue with a scalpel, an electrosurgery tip or a dental laser. Each tool cuts and controls bleeding differently, but the anatomy removed is the same, and current evidence does not show that one tool produces a different long-term gum position than another.
Once the excess tissue is gone, the exposed part of the tooth is usually the natural enamel crown that was always there. That is the key point for anyone with altered passive eruption: gum contouring does not lengthen the tooth. It unveils tooth that was already present. If the tooth beneath is short or worn, contouring alone will not create a longer-looking tooth, and this is where expectations often need adjusting.
The wound left behind is an open, superficial surface rather than a sutured flap. It heals from the edges inward, much like a graze on the skin, and the new gum margin settles into place over the following weeks as described in the healing section below. Because bone is untouched, the procedure is relatively brief, and several teeth can be treated in one visit if the assessment supports it.
The limitation is equally simple. Gum tends to re-establish a fixed thickness of tissue above bone. Remove gum too close to bone and the body rebuilds it. Contouring works when there is genuinely spare gum to give.
What does crown lengthening actually change?
Crown lengthening is a periodontal surgery that exposes more tooth by repositioning the gum and, when the bone sits too high, reshaping the bone as well. The word “crown” here means the natural crown of the tooth, the part above the root, not an artificial cap, although the procedure is often done to make room for one.
Under local anesthetic, the clinician makes an incision along the gum and lifts a small flap so the bone becomes visible. Using fine hand instruments or rotary tools under water spray, a thin layer of bone is removed and smoothed to a new, lower level around the necks of the teeth. The flap is then repositioned at the intended height and held with sutures. A protective dressing may be placed for the first several days.
The purpose of reducing bone is to preserve a stable relationship between bone crest and gum margin. Gum attached to a tooth needs a certain vertical zone of healthy fibers and epithelium above the bone; if a gum line is placed lower than that zone allows, the tissue rebounds or becomes chronically inflamed. Lowering the bone lets the gum sit lower too, permanently.
Crown lengthening comes in two flavors. Esthetic crown lengthening treats several front teeth to correct a gummy smile when contouring would be insufficient. Functional crown lengthening treats a single tooth, often a molar broken near the gum or one with decay running under the margin, so a dentist can seat a restoration on sound tooth structure with a proper seal.
Because bone remodels slowly, the final gum position takes considerably longer to settle than after contouring. That timeline, and why it matters if crowns or veneers are planned, is covered later. Crown lengthening is the more invasive of the two procedures, but it is also the one that produces a change that does not depend on the gum staying put by good fortune.
Gum contouring vs crown lengthening: the side-by-side view
Patients often hear both terms in one appointment and leave unsure which was recommended. The table below sets the two procedures next to each other on the points that come up most. Figures on timing are typical ranges quoted in periodontal teaching rather than guarantees, and individual healing varies with tissue thickness, oral hygiene and general health.

| Feature | Gum contouring | Crown lengthening |
|---|---|---|
| Tissue changed | Gum only | Gum and, usually, bone |
| Main problem addressed | Excess or overgrown gum over full-length teeth | Bone sitting too high, or tooth structure too short for a restoration |
| Anesthetic | Local | Local; sedation sometimes discussed |
| Sutures | Rarely | Yes |
| Early soft-tissue healing | Around one to two weeks | Around one to two weeks for the surface; bone settles over months |
| Stability of new gum line | Depends on adequate distance from bone | Designed to be stable once bone heals |
| Typical follow-up restorative work | Often none | Final crowns or veneers usually delayed until healing matures |
| Who usually performs it | General dentist or periodontist | Periodontist, sometimes an oral surgeon |
Two rows deserve emphasis. “Stability” is the honest dividing line: contouring holds when the anatomy allows, whereas crown lengthening changes the anatomy so it holds. “Follow-up restorative work” matters for anyone whose smile plan includes veneers, because a gum margin still moving under a new veneer edge can leave a dark line or a step within a year.
Neither column is “better.” A person with thick gums over intact teeth would gain nothing from bone removal. A person whose bone crest sits at the enamel edge would gain only temporary results from trimming gum. Matching the procedure to the measurement is the whole exercise.
What is biologic width, and why does it decide the procedure?
“Biologic width” is the dental term for the band of gum tissue that attaches to the tooth just above the bone: a zone of connective tissue fibers plus a thin layer of attached epithelium. In classic anatomical studies it measures a little over two millimeters on average, and the shallow groove of the gum collar sits above that. Think of it as the mortar line the body insists on keeping between bone and the open edge of the gum.
This zone is not decorative. It seals the tooth against bacteria and anchors the gum. When a restoration margin or a surgical gum line intrudes into it, the body responds in one of two ways. Either it rebuilds the lost tissue, pushing the gum back up toward where it started, or it resorbs bone downward to recreate the width, which can leave the gum inflamed, tender and prone to bleeding around the edge of a crown.
Here is how that plays out in the gummy smile consultation. The clinician measures from the planned new gum line down to the bone using a probe pushed gently through the anesthetized gum, a step called “bone sounding.” If the distance is comfortably more than the biologic width plus a normal groove depth, gum contouring alone should hold. If the distance is at or below that threshold, only crown lengthening, with bone reduction, will allow the gum to stay where it is placed.
The concept also explains a frequent disappointment. Someone has gum trimmed with a laser, loves the result for three months, then watches the gum line creep back. Nothing went wrong technically; the tissue simply reasserted its required dimension over bone that was never moved. Any clinician proposing contouring for a gummy smile should be able to tell you what the bone sounding showed and why it supports soft tissue alone.
Who is usually offered gum contouring, and who is asked to wait?
Gum contouring tends to suit adults whose front teeth are fully formed and whose X-rays show bone sitting well below the enamel edge, with excess gum draped over an otherwise normal crown. It also suits people with uneven gum margins, where one tooth looks shorter than its neighbor because the tissue scallop is irregular rather than because the tooth is. Mild overgrowth that has already been treated at its root, for example inflammation that settled after professional cleaning and improved brushing, may leave a fibrous excess that contouring can tidy.
Several groups are commonly asked to pause or are steered elsewhere.
- Anyone with active gum disease. Trimming inflamed, bleeding tissue is unpredictable, and the underlying infection continues. Gingivitis and periodontitis are treated first; guidance from bodies such as the NHS emphasizes plaque control and professional cleaning as the foundation before any elective gum work.
- Adolescents whose teeth are still erupting. Gum position continues to change into the early twenties, and cutting tissue that would have receded on its own is unnecessary.
- People whose gum overgrowth is linked to a medicine. Certain anticonvulsants, some calcium channel blockers and some immunosuppressants are associated with gingival enlargement. Surgery without addressing the trigger often leads to regrowth; the prescribing clinician decides whether any change is appropriate, never the dental team alone and never the patient acting independently.
- Smokers and people with poorly controlled diabetes, in whom healing is slower and the risk of complication higher; this is a conversation about timing and risk, not exclusion.
- Anyone whose gummy smile is actually driven by a hyperactive lip or vertical jaw excess, for whom gum removal would expose root and create sensitivity without changing the picture.
None of these is a permanent no. They are reasons a careful team sequences treatment rather than starting with a scalpel.
Who is usually offered crown lengthening?
Crown lengthening is proposed when the assessment shows that gum alone cannot be moved safely. The most common esthetic scenario is altered passive eruption with the bone crest close to the enamel margin. Removing gum here would breach biologic width, so bone is reshaped to allow a lower, stable gum line. The result looks like contouring from the outside, but the mechanism underneath is entirely different.
The functional scenario is even more common in everyday dentistry and rarely has anything to do with appearance. A molar fractures near the gum. Decay burrows under an old filling to a level below the gum line. A tooth is so short after years of grinding that a crown would have nothing to grip. In each case the dentist needs a margin of sound tooth above the gum, with healthy biologic width preserved beneath it. Crown lengthening creates that margin; the alternative is often extraction.
Candidates for esthetic crown lengthening are usually adults with fully erupted teeth, healthy periodontal status and realistic goals. The team also checks root length on X-ray. Because bone is removed, a tooth with short roots may end up with less support than it should have; a clinician will weigh how much bone can be sacrificed without compromising the tooth’s long-term stability.
People who are typically asked to wait or reconsider include those with untreated periodontitis, those with bleeding disorders or on anticoagulants whose medical team has not yet been consulted, and those whose smile complaint is mainly a high lip line. Someone planning veneers or crowns on the front teeth also needs patience: the final restorations are usually delayed until the gum has matured, and pushing that sequence for a deadline risks an uneven margin later.
As with contouring, the decision belongs to the treating team, informed by measurement rather than by how the smile looks in a photograph.
Gummy smile treatment options that are not gum surgery
A gummy smile caused by the lip or the jaw does not improve with either procedure discussed here, and a thorough consultation should mention the alternatives rather than defaulting to the one the clinic performs.
For a hyperactive upper lip, one that lifts unusually far when smiling, two approaches are discussed. The first is a small oral surgery sometimes called lip repositioning, which shortens the inner lining of the upper lip so it cannot rise as high. The second involves botulinum toxin, a medicine that temporarily weakens the muscles that elevate the lip. It works by blocking the signal between nerve and muscle for a period of months, after which the effect wears off and would need repeating. Whether it is appropriate, and everything about how it might be used, sits with a qualified prescriber; the point here is only that the mechanism targets muscle, not gum, so it addresses a different cause.
For a short upper lip, the same conversation applies in reverse: the lip itself, not the gum, is the limiting structure, and gum removal only exposes root.
For vertical maxillary excess, where the upper jaw is long, orthodontics may reduce the display by moving the front teeth upward, and in pronounced cases a combined orthodontic and jaw-surgery plan is discussed. This is a major undertaking and is chosen for functional bite reasons as often as for appearance.
Some people have more than one cause at once: a little excess gum plus a lively lip. A team that measures each component can explain which fraction of the display each treatment would change, and a patient can then decide whether the remaining display is acceptable. Choosing no treatment is also a legitimate outcome; gingival display is a normal variant, and many faces are widely admired with it.
Gum contouring healing time: what the first days and weeks look like
Because gum contouring leaves a superficial wound without a flap, most of the recovery happens in the first two weeks, and the experience is closer to a burn on the roof of the mouth than to surgery in the usual sense.
On the day itself, numbness wears off over a few hours and the treated area feels raw. A soft, cool diet is generally suggested, and hot, spicy or crunchy foods are avoided because they sting and can disturb the healing surface. Mild swelling and a tight feeling are common. Over-the-counter pain relief may be recommended by the clinician; the choice and any instructions are theirs to give, and this article does not describe them.
Within a few days a whitish or grayish film usually forms over the wound. It is not infection; it is fibrin, the protein scaffold the body lays down before new epithelium grows across. Brushing is typically continued on other teeth from day one, while the treated area is cleaned gently as instructed, sometimes with a prescribed rinse, to keep plaque from settling into the wound.
By about one to two weeks the surface has usually re-epithelialized, meaning a thin new skin covers it, and eating returns to normal. The gum, however, is not finished. It remains slightly swollen and pink-red for several more weeks, and the final position of the margin is not judged reliably until roughly six to eight weeks or longer, as the tissue matures and any minor rebound declares itself. Follow-up at this point is where the team checks whether the result matches the plan.
Sensitivity to cold at the newly exposed enamel-root junction is possible and generally settles. Persistent sensitivity, a margin that keeps rising, or bleeding that does not stop are reasons to return, as set out in the red-flag section.
Crown lengthening recovery time: why it is a longer road
Crown lengthening involves a flap and bone, so recovery has two clocks. The soft-tissue clock runs on roughly the same schedule as contouring. The bone clock runs for months, and it is the one that determines when the result is final.
In the first week, swelling and bruising are more noticeable than after contouring, occasionally spreading toward the lip or cheek. Sutures are usually removed or dissolve within about one to two weeks. A periodontal dressing, if placed, comes off at the first review. Soft foods, avoidance of chewing on the treated side, and careful cleaning around the sutures are the usual instructions. Cold sensitivity is common because some root surface is exposed after bone reduction, and it typically improves as the area seals.
Once the surface has healed, the gum margin continues to move. Immediately after surgery it sits where the surgeon placed it; over the following weeks it may creep upward slightly as swelling resolves and the tissue re-establishes its attachment over the new bone level. Periodontal teaching generally advises waiting a minimum of several weeks before any temporary restoration is adjusted and often around three to six months, sometimes longer in the esthetic zone, before final crowns or veneers are made, because a margin that is still settling under a new restoration can leave an exposed edge later. Your team will set the timing based on how your tissue behaves, not on a calendar.
For functional crown lengthening on a single back tooth, this waiting period is a mild inconvenience with a temporary crown in place. For esthetic cases on the front teeth it tests patience, and it is worth knowing before the first appointment that the finished smile is a matter of months, not weeks.
Bone itself remodels quietly throughout this time and requires no action from the patient beyond keeping the area clean and attending reviews.
What are the risks and trade-offs of each procedure?
Both procedures are established and commonly performed, but both are irreversible in the sense that removed tissue is not easily replaced, so the risks deserve a plain description.
Gum contouring carries the risks of any minor oral surgery: bleeding, infection, pain and swelling. Its specific risks follow from the anatomy explained earlier. If too little gum is removed the change is disappointing; if too much is removed the exposed root can become sensitive and, in thin tissue, the margin may recede further than intended. The most frequent “complication” is not really a complication at all: regrowth of the gum toward its original position when the bone was never assessed.
Crown lengthening shares those general risks and adds a few of its own. Removing bone reduces the support of the tooth by a small, planned amount; on teeth with short roots this can matter. Adjacent teeth are affected because bone is reshaped as a smooth contour, so a neighbor may end up looking slightly longer too. After the flap heals, the small triangles of gum between teeth may sit lower, leaving dark gaps sometimes called “black triangles,” more likely in people with thin, scalloped tissue. Root exposure raises the risk of root surface decay if plaque control is poor. Rarely, a tooth can become tender to bite or require root canal treatment afterward, particularly a tooth that already had deep decay or a large filling.
The alternative to both, for the esthetic patient, is doing nothing, and it is a genuine alternative. For the functional patient facing a broken molar, the alternatives are usually extraction with or without a replacement, and a periodontist will lay those out.
Neither procedure has a body of high-quality trials comparing long-term satisfaction, so any clinician who quotes a precise “success rate” should be asked where the number comes from. What the evidence does support is the anatomical principle: gum placed within biologic width tends not to stay there.
Does gum contouring grow back?
This is the question people type into search engines after their appointment, and the honest answer is: sometimes, and the reason is predictable.
Healthy gum tissue is not like hair. Once a strip is removed, that strip does not regenerate as new tissue in the way skin fills a shallow wound and stops. What happens instead is that the gum re-forms its required relationship with the bone beneath. If the new margin was placed with adequate distance above the bone, the tissue heals at roughly that level and stays. If the new margin sits too close to bone, the body rebuilds the missing biologic width by pushing the gum margin back upward, and within months the tooth looks nearly as short as before. Patients experience this as “my gums grew back.”
Two other situations mimic regrowth. The first is inflammation: gum that is not kept clean swells, and a swollen margin sits higher on the tooth. Improve plaque control and the margin often drops again. The second is the underlying cause returning, most often medicine-associated overgrowth or a hormonal driver, in which case surgery treated the result but not the source.
After crown lengthening with bone reshaping, meaningful regrowth of the gum margin is uncommon once healing has matured, precisely because the bone level was lowered to accommodate the new margin. Some upward drift in the first weeks is expected and is why final restorations are delayed.
The practical lesson is to ask, before contouring, whether bone sounding was done and what it showed. A clinician who can point to the measurement can also explain why regrowth is unlikely in your case, or why crown lengthening is the safer route. That conversation, more than any tool or technique, determines whether the result lasts.
What people often get wrong about gum contouring vs crown lengthening
Several beliefs circulate widely enough to deserve direct correction.
“A laser makes it permanent.” A laser is a cutting tool. It offers good bleeding control and, for some patients, less early discomfort, but it removes the same soft tissue a scalpel does. It cannot change where the bone sits, so it does not alter whether the gum rebounds.
“Crown lengthening means getting crowns.” The name refers to the natural crown of the tooth. Many esthetic crown lengthening cases finish with no restorations at all; the exposed enamel is simply the patient’s own tooth.
“More gum removed equals a better smile.” Over-reduction exposes root, invites sensitivity and can make teeth look unnaturally long. Esthetic guidelines used in dentistry describe the upper central incisors as pleasing when their width is roughly three-quarters to four-fifths of their length; going beyond that proportion tends to look worse, not better.
“It is a cosmetic-only procedure, so it carries no real risk.” Both procedures are surgery on tissue that does not regrow on demand, and both can produce sensitivity, recession or black triangles if planned poorly.
“Any gummy smile can be fixed with gum work.” Lip mobility and jaw height account for a large share of gummy smiles and are untouched by either procedure.
“Teenagers should have it early, before the smile is set.” Gum position keeps changing as eruption completes, which is why most clinicians wait until the early twenties for esthetic cases.
“Swollen gums are just extra gum.” Bleeding, puffy tissue is usually inflammation from plaque or gum disease, a treatable condition described by organizations such as the CDC and NHS as the leading cause of gum changes in adults. Treat that first; the “gummy” look may shrink on its own.
Each of these myths shares a root: treating the visible gum as the problem instead of asking what put it there.
Questions to ask your care team before choosing
A good consultation is a two-way exchange, and the questions below tend to surface the information that separates a durable result from a disappointing one. They are offered as a starting point rather than a script.
- What is causing my gummy smile: gum, lip, jaw, or a combination, and roughly what share of the display comes from each?
- Did you measure the distance from my planned gum line to the bone? What did the bone sounding or X-ray show, and does it support removing gum alone?
- If you recommend crown lengthening, how much bone would be reshaped, and how long are the roots of the teeth involved?
- Will the neighboring teeth be affected so the contour stays smooth, and how will that change their appearance?
- Am I at higher risk of black triangles or root sensitivity based on how thin my gum tissue is?
- Do I have any gum inflammation or disease that should be treated first, and what would that involve?
- Could any medicine I take be contributing to gum overgrowth, and would you want to speak with the clinician who prescribes it? (Any change to a prescription is their decision, never something to attempt alone.)
- If I am planning veneers or crowns later, how long will you want the gum to settle before the final restorations are made?
- What does your follow-up schedule look like, and at what point will we judge the final position of the gum line?
- What happens if the gum rebounds, and is a second procedure something you would consider?
- What would you expect if I chose no treatment at all?
Write the answers down or ask for them in a treatment letter. The measurements in particular, the probing depths and the bone-to-margin distance, are worth having on paper, because they are the evidence behind the recommendation and can be shared with any second clinician you consult.
When to call your doctor or dentist after gum surgery
Most people recover from gum contouring or crown lengthening with soreness, mild swelling and a few days of careful eating. A small number develop problems that need prompt attention, and knowing the difference saves worry in both directions.
Contact the treating clinic the same day, or seek urgent care if it is closed, for any of the following.
- Bleeding that soaks through gauze and does not slow after twenty to thirty minutes of firm, steady pressure, or bleeding that restarts heavily after it had stopped.
- Swelling that keeps increasing after the second or third day, spreads toward the eye, floor of the mouth or neck, or makes it hard to open the mouth, swallow or breathe. Difficulty breathing or swallowing is an emergency: call emergency services.
- Fever, chills, or a spreading, hot, red area of gum or cheek, which can indicate infection.
- Pain that worsens rather than eases after the first few days, or pain that is not controlled by the measures your clinician recommended.
- A foul taste or discharge from the wound, or a dressing or sutures that come loose early and leave the area exposed and painful.
- Numbness of the lip, chin or tongue that persists beyond the expected wearing-off of the anesthetic.
- A tooth that becomes loose, or a tooth that throbs on its own or is severely sensitive to heat, which may signal that the nerve inside is inflamed.
In the longer term, return for review if the gum margin visibly rises or recedes weeks after healing, if new dark triangles appear between teeth, if cold sensitivity does not fade after a couple of months, or if gums anywhere in the mouth bleed on brushing, since that points to inflammation that undermines any gum work.
Every one of these situations is a judgment for the treating team. They know what was done, where the bone now sits and how your tissue has behaved so far, and they are the right people to decide whether a phone call, an early appointment or emergency care is needed.
Frequently asked questions
Is gum contouring the same as crown lengthening?
No. Gum contouring reshapes only the gum, while crown lengthening repositions the gum and usually removes a thin layer of bone as well. Both can make teeth look longer, but contouring depends on there being enough gum above the bone to remove safely, whereas crown lengthening changes the bone level so the new gum line is designed to remain stable once healed.
How long does gum contouring healing time usually take?
The surface typically closes over within about one to two weeks, during which a soft diet and gentle cleaning are usually advised. The gum then continues to mature and its final position is generally not judged until roughly six to eight weeks or longer. These are typical ranges from periodontal teaching, not promises; your clinician will tell you what to expect for your tissue.
What is crown lengthening recovery time compared with contouring?
Early recovery is similar, with sutures usually removed or dissolving within one to two weeks and swelling settling over that period. The difference is the bone, which remodels over months. Clinicians commonly wait several weeks before adjusting temporaries and often around three to six months, sometimes longer on front teeth, before final crowns or veneers, so the gum margin has stopped moving.
Does gum contouring grow back after the procedure?
It can appear to, and the usual reason is that the new gum line was placed too close to the underlying bone. The body then rebuilds its required attachment zone, pushing the margin upward. Inflammation from plaque and a returning underlying cause, such as medicine-related overgrowth, can also make the gum look higher again. Bone sounding before treatment is the main way to predict whether regrowth is likely.
Which gummy smile treatment options do not involve gum surgery?
For a lip that lifts unusually high, options discussed include a lip-repositioning surgery and botulinum toxin, a medicine that temporarily weakens the lifting muscles for a period of months. For a long upper jaw, orthodontics or combined orthodontic and jaw surgery may be considered. Choosing no treatment is also reasonable, since gum display is a normal variation. Which, if any, applies depends on measurement by your care team.
Does crown lengthening mean I will need crowns on my teeth?
Not necessarily. The name refers to the natural crown of the tooth, the part above the root. Esthetic crown lengthening for a gummy smile often ends with no restorations because the exposed enamel is your own tooth. Functional crown lengthening on a single damaged tooth is usually done so a crown can be fitted on sound structure, which is where the two meanings overlap.
Is a laser better than a scalpel for gum contouring?
Current evidence does not show that a laser produces a different long-term gum position than a scalpel or electrosurgery. Lasers offer good bleeding control and some patients report less early soreness, but the tissue removed is the same. Whether the result lasts depends on the distance between the new gum line and the bone, not on the instrument, so ask about that measurement rather than the tool.
Can teenagers have gum contouring for a gummy smile?
Most clinicians prefer to wait until tooth eruption is complete and the gum has reached its adult position, which is often in the early twenties. Gum margins continue to move upward naturally during adolescence, so trimming early can remove tissue that would have receded on its own. Any decision about timing sits with the treating dental team after examining the individual.
Will crown lengthening weaken my teeth?
It removes a small, planned amount of bone support, which is why root length is checked on X-ray beforehand. On teeth with normal roots the reduction is generally well tolerated; on short-rooted teeth the team may advise against it or limit the amount. Neighboring teeth are included in the bone contour to keep it smooth, and this is discussed as part of consent.
Should I treat bleeding gums before considering either procedure?
Yes, in almost all cases. Bleeding, puffy gums usually indicate gingivitis or periodontitis, which organizations such as the NHS and CDC describe as plaque-driven conditions treated with professional cleaning and improved daily hygiene. Operating on inflamed tissue heals unpredictably, and swelling can make gums look excessive when they are not. Once inflammation settles, the assessment for contouring or crown lengthening is far more accurate.
