Gummy Smile Correction

At COSDENT, we believe a confident smile is a powerful tool. Using advanced laser technology, we can precisely reshape your gum line to reveal the natural beauty of your teeth.

What is a gummy smile?

A gummy smile — clinically known as excessive gingival display — occurs when more than 2–3mm of gum tissue is visible above the upper teeth when smiling. In most cases, the teeth themselves are perfectly healthy and normal in size. It’s the position and volume of the gum tissue that creates the appearance of shorter teeth and a smile dominated by gum rather than tooth.

The good news: for the majority of people with gummy smiles, the correction is simpler, faster, and less invasive than most expect. At COSDENT, laser gum contouring typically takes under an hour, requires no stitches, and delivers a visible result the same day.

What causes a gummy smile?

Not all gummy smiles are the same — and not all respond to the same treatment. The cause behind your specific gummy smile determines whether laser contouring is the right solution, or whether a different approach is needed. At COSDENT, we assess this at your first consultation — so you’re never investing in a treatment that won’t work for your case.

1. Excess gum tissue

The gums simply cover more of the tooth surface than they should. The teeth are full-sized underneath — they’re just hidden. The most common cause, and the most responsive to laser contouring.

2. Altered passive eruption (short clinical crown)

The gum hasn’t fully receded after the teeth finished erupting — leaving teeth appearing shorter than they are. Laser precisely removes the excess gum to reveal the full tooth length.

3. Hyperactive upper lip

The upper lip rises higher than normal when smiling — exposing more gum regardless of gum tissue volume. Often combined with laser gum contouring or addressed with Botox to the lip elevator muscles.

4. Vertical maxillary excess

The upper jaw bone has grown longer than normal — a skeletal cause that affects the entire facial structure. Laser alone cannot fully correct this; orthognathic surgery is typically required.

At your COSDENT consultation: We identify your gummy smile type before recommending any treatment. If laser contouring is the right solution, we’ll show you a digital preview of your result. If a different or combined approach would serve you better, we’ll tell you that too — honestly, before anything begins.

How does laser gum contouring work?

The procedure is more precise — and more comfortable — than most patients expect. Using COSDENT’s Beam of Beauty laser platform, the entire treatment is completed in a single visit, without a scalpel, without stitches, and with minimal discomfort throughout.

1. Smile design mapping

Before any treatment begins, your dentist maps the ideal gum line digitally — analysing your facial proportions, lip line, tooth length, and midline. The new gum contour is planned to the millimetre. You see the proposed result before we start.

2. Anaesthetic — comfort from the start

A topical numbing gel is applied first, followed by a local anaesthetic injection. Once the area is fully numb, the treatment proceeds without pain. Most patients report feeling only light pressure — nothing more.

3. Laser contouring with Beam of Beauty

The laser precisely removes and reshapes the gum tissue along the pre-planned line. Unlike a scalpel, the laser simultaneously seals the tissue as it works — which means no stitches are needed and bleeding is kept to a minimum. Each tooth takes only minutes. The entire contouring session typically completes within 30–45 minutes.

4. Immediate visible result

You’ll see the new gum line as soon as the procedure is complete. The teeth look longer, more proportionate, and the smile looks immediately more balanced. Some minor swelling over the following days is normal and resolves quickly.

5. Recovery — easier than most expect

• Soft foods for 3–5 days.

• Avoid smoking, spicy food, and alcohol during the first week.

• Mild soreness manageable with standard pain relief.

Most patients return to normal activities the same afternoon or the following morning. Final healed result is clear within 1–2 weeks.

Who is it suitable for gummy smile correction?

Laser gum contouring gives excellent results for the right candidate — and at COSDENT, we assess every patient’s suitability before recommending treatment. Here’s an honest guide to who benefits most, and when a different approach may be needed.

• Excess gum tissue — Gums covering healthy full-size teeth — the most common cause and the clearest candidate for laser.

• Short-looking teeth — Teeth appear short but are full-size — altered passive eruption is highly responsive to laser contouring.

• Healthy gums (no active disease) — Gum health is confirmed before treatment. Active gum disease is resolved first if present.

• Adults (18+) — Treatment is for fully developed teeth and jaw — not recommended while facial growth is still ongoing.

• Dental tourists with 3–5 days in Bangkok — Same-day results and next-day return to activities make this ideal for short-stay international patients.

• Patients combining with veneers — Gum contouring first, then veneer design — the logical sequence for full smile transformation in one trip.

When laser may not be enough

• Skeletal jaw cause (vertical maxillary excess) — When the upper jaw bone itself is overgrown, laser treats the surface but not the underlying structure. An honest assessment will identify this early.

• Hyperactive upper lip alone — If the gum tissue itself is normal but the lip rises too high, Botox to the lip elevator muscles may be the primary treatment, with laser as a complement.

• Active gum disease — Must be fully treated before any cosmetic gum procedure. We’ll advise if this applies to you at your consultation.

What’s the difference between laser gum contouring and surgical gum correction?

These 2 methods can achieve gummy smile correction. The approach used determines how comfortable the experience is, how long recovery takes, and whether the procedure fits within a short Bangkok trip. Here’s an honest comparison.

FAQ

1. How stable are laser gum contouring results?

Results can be long-lasting, but tissue response and stability vary. Your dentist will explain what to expect for your case and how maintenance affects the outcome. This is one of the most important distinctions from some other cosmetic procedures that require ongoing maintenance.

2. Does it hurt?

During the procedure: no — the area is fully numbed with local anaesthetic. Most patients feel only light pressure. After the anaesthetic wears off, mild soreness for 2–4 days is normal and manageable with standard pain relief (ibuprofen or paracetamol). Most patients describe the recovery as much easier than they expected.

3. How long does the procedure take?

The laser contouring itself typically takes 30–45 minutes for the upper front teeth. Including preparation, anaesthetic, and post-treatment review, most appointments take 1.5–2 hours.

4. How many days do I need in Bangkok?

For gummy smile correction alone: a minimum of 3 days is comfortable — consultation Day 1, treatment Day 2, recovery Day 3. Five days allows for a follow-up check and a more relaxed recovery experience. For combined gum + veneer treatment, 7–10 days or two separate trips is recommended.

5. Will my gums grow back after laser treatment?

No. Gum tissue removed by laser does not grow back. The result can be long-lasting, although tissue response varies. The gum line may appear to settle slightly as post-treatment swelling resolves over 1–2 weeks — but this is the tissue finding its final position, not regrowth.

6. Can I combine gummy smile correction with veneers in one trip?

Yes — and it’s often the most efficient approach for patients wanting a complete smile transformation. Gum contouring is done first, then veneers are designed to the new proportions. A 7–10 day stay covers both procedures for temporary veneer placement, with final ceramics fitted on a return visit.

7. Is laser gum contouring safe?

Yes — laser gum procedures have an established safety record in cosmetic dentistry. At COSDENT, the Beam of Beauty laser platform is used by trained and experienced clinicians, with precise pre-treatment planning to protect healthy tissue. Complications are rare and typically minor when performed by a qualified team.

8. How do I know if my gummy smile can be fixed with laser?

The most reliable way is a consultation — but you can get a preliminary answer remotely. Send us clear photos of your smile (front-facing, smiling fully) via LINE or email, and our team will assess whether laser contouring applies to your case before you commit to travelling.

9. How long is the recovery after laser gum contouring?

Recovery after laser gum contouring at COSDENT is quick, with most patients returning to normal activities within one to two days. Because our laser technology cauterizes tissue as it reshapes your gum line, you’ll experience significantly less bleeding and swelling than with traditional scalpel methods—and healing is up to 50% faster.

Here’s what to expect during recovery:

• Days 1–2: Mild soreness, easily managed with over-the-counter pain relief. Most patients resume work and light activities.

• First week: Stick to soft foods and avoid hard, crunchy, or spicy items. Skip strenuous exercise for about five days.

• 1–2 weeks: Initial healing is complete, and your reshaped gum line settles beautifully.

• 4–6 weeks: Gum tissue fully matures into its final, refined state.

10. Can I get gummy smile treatment done as a tourist in Bangkok?

Yes, gummy smile treatment is ideal for visitors to Bangkok. Laser gum contouring at COSDENT is a single-session procedure, typically completed in one to two hours, with results visible the same day. This makes it one of the most convenient cosmetic dental treatments for international patients and expats.

A few things to keep in mind when planning your visit:

• Consultation and treatment can often be scheduled efficiently within your trip.

• Recovery is minimal, so we recommend staying in Bangkok for a few days afterward to enjoy the city while your gums settle.

• English-speaking specialists guide you through every step, from assessment to aftercare.

Many patients pair their treatment with a relaxing Bangkok getaway, returning home with a refreshed, confident smile.

11. Can gummy smile correction be combined with veneers?

Yes, gummy smile correction and veneers work beautifully together—but the sequence matters. At COSDENT, we always perform laser gum contouring first to establish your ideal gum line, then design veneers around that refined foundation. This order ensures your final result is perfectly proportioned and natural-looking.

Why sequencing is important:

• Gum contouring first creates the ideal canvas, so veneers are sized and shaped to complement your new gum line.

• Healing time of roughly 8–12 weeks allows gum tissue to fully stabilize before veneers are placed.

• Planning options: Some international patients complete gum contouring on one visit and return for veneers on a later trip, while others coordinate timing within an extended stay.

During your consultation, our specialists assess your suitability for both treatments and craft a tailored plan to achieve your dream smile.
