Gum Contouring for a Gummy Smile: What Melbourne Cosmetic Dentists Can Reshape — and What It Costs

Have you ever looked at a photo of yourself mid-laugh and felt that something about the smile was slightly off, without being able to name it? If your teeth look short, square, or a little uneven in those photos, there is a good chance the proportion of gum to tooth is doing most of the work.

Gums frame teeth the way a mount frames a print. When that frame sits low, runs unevenly across the front six, or covers more enamel on one side than the other, perfectly healthy teeth can read as small and stubby.

Published smile-aesthetics research generally reports that a full smile showing between zero and two millimetres of gum reads as balanced to most observers, while a display beyond roughly three to four millimetres begins to be described as gummy. That is a narrow margin, which is exactly why a millimetre or two of reshaping can change how an entire smile is read.

What follows is how the procedure actually works, when it is worth pairing with porcelain veneers in Melbourne or composite bonding, when it is the wrong tool altogether, and what you should expect to pay in $AUD.

What Gum Contouring Actually Is

Gum contouring — also called gingival sculpting, gingivoplasty, or a gum lift — is the controlled removal and reshaping of a small amount of gum tissue so that more of the tooth beneath it shows. It is measured in fractions of a millimetre, and the tooth structure itself is left untouched.

Most cosmetic cases fall into one of three jobs: lifting a gum line that sits too low across the whole smile, levelling a margin that runs higher on one tooth than its twin on the opposite side, or reshaping the gingival zeniths so the front teeth regain proper width-to-height proportion. Of course, a good result depends on healthy tissue first, so active gum disease is treated and settled before any aesthetic reshaping begins.

Keep in mind that this is a soft-tissue procedure with a hard biological limit. Where the underlying bone sits too close to the intended new gum line, tissue alone cannot be reshaped predictably, and the case becomes a surgical crown lengthening instead.

Why Some Smiles Show More Gum Than Others

Excess gum display has several distinct causes, and treatment only works when the right one has been identified. The causes we see most often in Melbourne practice include but are not limited to:

• Altered passive eruption. The teeth erupted normally but the gum never finished migrating to its adult position, leaving enamel permanently covered. This is the classic case for laser contouring, because there is real tooth waiting underneath.
• A short or hyperactive upper lip. A lip that travels more than roughly eight millimetres between rest and full smile will expose gum regardless of how the tissue is shaped.
• Vertical maxillary excess. The upper jaw is longer than average, which carries the whole dental arch and its gum line downward. This is a skeletal pattern rather than a tissue one.
• Medication-related gingival overgrowth. Phenytoin, ciclosporin, and calcium channel blockers such as nifedipine and amlodipine are all associated with tissue enlargement. Reshaping helps, though the tissue tends to return unless the medication or the plaque control changes.
• Inflammation and hormonal change. Puberty, pregnancy, and long-standing plaque accumulation all swell the gum margin, sometimes enough to mimic a structural problem.
• Worn teeth. Years of clenching or grinding shorten the incisal edges while the gum line stays where it is, so the teeth look progressively squarer — a pattern covered in our guide to veneers and teeth grinding.

All of these produce a broadly similar-looking smile and a completely different treatment plan. This is why the assessment matters far more than the laser does.

How Much Gum Showing Is Too Much?

There is no single measurement that makes a smile attractive, though there are working reference points that cosmetic dentists design around. A central incisor that reads as well-proportioned is usually somewhere around 75 to 85 percent as wide as it is tall, and the gum zeniths of the two central incisors should sit level with one another.

The lateral incisors generally look best with their margin sitting around half a millimetre to a millimetre below the centrals, while the canines return to roughly the level of the centrals. Note that these are starting points for a design conversation rather than rules, because face shape, lip line, and age all shift what reads as natural on an individual.

In practice, that conversation starts with high-resolution photographs and a digital smile design preview rather than a ruler. Seeing a simulated gum line laid over your own photograph is the fastest way to work out whether one millimetre or three is what you are actually after.

How Laser Gum Contouring Is Done

The appointment itself is short. After local anaesthetic, the planned margin is marked against the agreed design, and a soft-tissue diode or erbium laser removes tissue in fine passes while sealing the capillaries as it goes.

Because the laser cauterises as it cuts, bleeding is minimal and sutures are usually unnecessary. Reshaping six to eight teeth generally takes 30 to 60 minutes in the chair.

Before any of that, your dentist measures how much room exists between the intended new margin and the bone underneath. Approximately two millimetres of supracrestal attachment — the band of connective tissue and epithelium that seals the tooth to the bone — must be preserved, or the tissue will simply regrow to reclaim it.

Where the measurement shows too little room, the correct procedure is a crown lengthening: a small flap is raised, a conservative amount of bone is recontoured, and the tissue is repositioned. That is a longer appointment with a longer settling period, and it is the step that separates a stable result from one that relapses within months.

Soft-Tissue Contouring Or Crown Lengthening?

The two procedures are often discussed as though they were one, yet they differ in what is removed, how long they take to settle, and what they cost. Here is how they compare:

Factor	Laser gum contouring	Surgical crown lengthening
What is removed	Soft tissue only	Soft tissue plus a conservative amount of bone
Anaesthetic	Local	Local, sometimes with sedation
Chair time	30 to 60 minutes	60 to 120 minutes
Sutures	Rarely needed	Usually placed, removed in 7 to 10 days
Settling time before veneers	4 to 8 weeks	10 to 16 weeks
Typical Melbourne fee	$150 to $400 per tooth	$1,500 to $4,000 per arch segment
Best suited to	Altered passive eruption, minor asymmetry	Cases where bone sits close to the desired margin

Both procedures can sit inside the same treatment sequence, and plenty of smiles need simple contouring on most teeth and crown lengthening on one or two others. What matters is that the decision follows the bone measurement rather than the fee.

When Contouring Pairs With Veneers Or Bonding

Gum contouring is frequently the first step of a larger plan. Once the margin sits where it should, the teeth that were hiding underneath are often the correct length but the wrong shade, shape, or width.

That is where composite bonding or veneers come in. Bonding is the lighter-touch option for rebuilding worn edges and closing small gaps, while porcelain handles larger changes in shape and colour — a trade-off we unpack in our comparison of bonding versus veneers.

Sequencing is the part patients most often get wrong. The gum margin needs four to eight weeks to mature and stabilise after laser contouring before veneer or bonding preparation begins, because margins prepared against a still-settling gum line end up sitting visibly short once the tissue finishes maturing.

If porcelain is on the table, it is worth reading our notes on who makes a good veneer candidate and on achieving a natural-looking veneer result before the design appointment. Remember that anyone looking at your face judges the gum frame and the porcelain together, so they should be designed together too.

What Recovery Actually Feels Like

Most patients are surprised by how mild this is. The anaesthetic wears off over two to three hours, and what follows is usually described as tenderness or a scraped sensation rather than pain.

Paracetamol or ibuprofen is generally enough for the first day or two. Be aware that the treated margin will look pale or greyish-white for the first few days as it heals, which is an expected part of laser healing.

For the first three to five days, stay with softer foods and avoid anything very hot, acidic, or heavily spiced. Keep brushing throughout, using a soft brush and a gentle touch at the gum line, along with any rinse your dentist prescribes.

The contour looks close to final within about two weeks and fully matures by six to eight. If whitening forms part of the plan, it is generally scheduled once the tissue has settled — our guide to teeth whitening in Melbourne covers where it belongs in the sequence.

Do The Results Last?

When tissue is reshaped inside its biological limits, the new contour is effectively permanent. The gum has no reason to migrate back down, and the result holds for years.

Relapse has predictable causes. Encroaching on the supracrestal attachment without recontouring bone is the main one, followed by ongoing inflammation from plaque, smoking, and the medication-related overgrowth described earlier.

Accordingly, the maintenance advice is unglamorous and effective: brush gently along the margin twice daily, clean between the teeth every day, and keep to your regular hygiene appointments. Patients on nifedipine, amlodipine, ciclosporin, or phenytoin should mention it at the consultation so the plan accounts for the higher chance of regrowth.

When Gum Contouring Is Not The Right Answer

Honest assessment sometimes means saying that the laser will not solve it. Where the gum display is driven by lip mobility or jaw position, reshaping tissue changes very little and can leave the teeth looking unnaturally long.

Alternatives your dentist may raise, alone or in combination, include:

• Botulinum toxin to the lip elevators. A few small injections reduce how far the upper lip travels, softening the display for roughly three to four months per treatment.
• Lip repositioning surgery. A strip of tissue inside the upper lip is removed to limit lift, giving a longer-lasting result than injectables for hyperactive lip cases.
• Orthodontic intrusion. Aligners or braces, often with temporary anchorage devices, move the front teeth upward so the gum follows them — relevant if you are already weighing up Invisalign in Melbourne.
• Orthognathic surgery. Reserved for significant vertical maxillary excess, where the upper jaw is surgically repositioned by a specialist team.

All of these sit outside a cosmetic laser appointment, and several require referral. A practice that raises them unprompted is telling you something useful about how carefully it diagnoses.

What Gum Contouring Costs In Melbourne

Fees move with how many teeth are treated, whether bone recontouring is required, and whether the contouring is a standalone visit or folded into a larger plan. The ranges below reflect what is typically quoted across Melbourne metro practices.

Treatment	Typical Melbourne range ($AUD)
Consultation, photographs and digital preview	$0 to $250
Laser contouring, single tooth	$150 to $400
Laser contouring, front six to eight teeth	$800 to $2,500
Surgical crown lengthening, per arch segment	$1,500 to $4,000
Contouring folded into a veneer or bonding plan	Often reduced or absorbed into the case fee

Ask for an itemised treatment plan listing the Australian Dental Association item number for each step rather than a single lump sum. That itemisation is what lets you compare quotes honestly, and it is what your health fund needs in order to assess a claim.

Where contouring forms one step of a broader plan, the economics shift — a gum lift costing a few hundred dollars can reduce how much porcelain the case ultimately needs. Our overview of smile makeovers in Melbourne sets out how the individual line items usually stack up.

Health Funds, HICAPS And Payment

Purely cosmetic reshaping is generally not claimable under extras cover. Where the same procedure is performed for periodontal reasons — pocket reduction, medication-related overgrowth, restoring cleansable contours — a portion may be payable under general or major dental, depending on your policy and your annual limits.

The reliable way to find out is a pre-treatment estimate, where your practice submits the proposed item numbers to your fund and the fund replies in writing with what it will pay. Most Melbourne practices, including ours, process rebates on the spot through HICAPS so that you settle only the gap.

Waiting periods apply to major dental with most funds, so it is worth checking your level of cover before booking if the plan is likely to extend into veneers or crowns. Our post on veneers and private health funds works through what is typically covered and what is not.

How To Judge The Plan Before You Commit

A well-run gum contouring appointment is decided long before the laser is switched on. The consultation should include full-face and retracted photographs, an assessment of your lip line at rest and at full smile, periodontal charting, and bone sounding or a radiograph to confirm the distance to the crest.

You should also see a preview of the intended result, and you should be told plainly which teeth are being treated and by how much. Ask what happens if the tissue regrows, and ask to see cases the practice has treated where the patient has consented to their photographs being shown.

If the plan is anchored to a wedding, a milestone birthday, or any fixed date, build the settling time into the schedule first — our wedding smile timeline works backwards from the day for exactly this reason.

Frequently Asked Questions

Does laser gum contouring hurt?

The gums are numbed with local anaesthetic, so the procedure itself is painless. Most patients describe the following days as mild tenderness rather than pain, managed with paracetamol and a softer diet.

How long do gum contouring results last?

Reshaping performed within the tissue's biological limits is effectively permanent. Regrowth is mainly a risk where inflammation, poor plaque control, smoking, or certain medications drive the tissue back down.

What are the risks of gum contouring?

Removing too much tissue can expose root surface, cause sensitivity, or leave a tooth looking long. Measuring the supracrestal attachment first, and recontouring bone where needed, is what prevents both problems.

Can gum contouring be done on the lower teeth?

Yes, though it is requested far less often because the lower gum line is rarely visible when smiling. It is more commonly done on lower teeth for hygiene access or before restorative work.

How soon can I go back to work?

Most patients return the same day or the next morning. There is no visible swelling in typical soft-tissue cases, though speaking may feel slightly odd for a few hours while the anaesthetic wears off.

Is gum contouring suitable during pregnancy?

Elective cosmetic reshaping is generally deferred until after pregnancy. Hormonal changes swell the gum margin temporarily, so a contour designed during that period may not match the settled tissue afterwards.
