Gum Contouring

When teeth appear short, asymmetrical, or overshadowed by the surrounding gingival tissue, the underlying teeth are often normal in size, it is the position and contour of the gumline that frames them unevenly. At COSDENT Smile Design, gum contouring (gingivoplasty and clinical crown lengthening) is planned around your facial proportions, lip dynamics, and periodontal architecture rather than a one-size-fits-all template.

Whether you are considering subtle symmetry refinement over a single front tooth or preparatory gumline architecture before porcelain veneers, this guide explains how our dental team at Siam and Rama 9 assesses your gums, selects between soft-tissue laser reshaping and conventional crown lengthening, and plans your recovery in Bangkok.

What gum contouring does and how it frames your smile

Gum contouring is a targeted periodontal and aesthetic procedure that reshapes or repositions the gingival margin around the necks of the teeth. In aesthetic dentistry, clinicians evaluate two complementary elements: white aesthetics (the shade, shape, and surface texture of the teeth) and pink aesthetics (the symmetry, zenith position, and health of the gums).

Even well-aligned teeth can look crooked or disproportionately small if the gingival zenith, the highest arc of the gumline on each tooth, sits at different heights between the left and right sides. By carefully adjusting the soft-tissue margin (and, where clinically indicated, the underlying crestal bone), gum contouring exposes the natural anatomical crown of the tooth and establishes a balanced horizontal frame across the upper smile zone.

Anatomical causes of an uneven or prominent gumline

Before recommending any reshaping, the dentist must identify why the gumline sits where it does. Treating every uneven gumline with the same instrument can lead to tissue rebound or persistent inflammation if the biological width is not respected.

• Altered passive eruption: As adult teeth finish erupting, the gum margin normally recedes slightly toward the root junction. When this natural recession stops early, healthy gum tissue remains covering a portion of the enamel, making full-sized teeth look short or square.

• Gingival asymmetry and localized overgrowth: Past orthodontic movement, mouth breathing, localized plaque irritation, or certain medications can leave the gum margin lower on one central incisor or canine than its neighbour.

• Tooth wear with compensatory eruption: When front teeth wear down from grinding (attrition), the teeth and their surrounding bone and gum slowly erupt downward together to maintain bite contact, bringing the gumline lower in the smile.

• Bony or skeletal prominence: In some patients, the underlying alveolar bone sits very close to the gum edge, or the upper jaw itself has vertical excess. Check our dedicated Gummy Smile Correction guide for how broader gingival display is evaluated.

Laser gingivoplasty vs surgical crown lengthening

At COSDENT, the choice between soft-tissue laser reshaping (using our Beam of Beauty laser platform) and conventional surgical crown lengthening is determined by periodontal probing and dental imaging, specifically measuring the distance between the desired new gumline and the underlying bone crest (the supracrestal tissue attachment).

Who is suitable for gum contouring

You may be a candidate for gum contouring after a clinical examination confirms that:

• Your gums are free from active periodontal disease or untreated gingivitis (if inflammation is present, professional cleaning and periodontal stabilisation come first).

• There is sufficient keratinized (attached) gum tissue so that reshaping leaves a healthy, protective collar of gum around each tooth.

• Exposing additional tooth structure will not expose root dentin in a way that causes unmanageable sensitivity or an unfavorable crown-to-root ratio unless a veneer or dental crown is planned to cover the area.

Step-by-step procedure at COSDENT

1. Clinical & radiographic assessment: Your dentist measures pocket depths, checks the width of attached gingiva, and takes digital photographs and X-rays to locate the bone crest relative to the enamel junction.

2. Digital smile design mapping: We map the proposed gingival zeniths on your smile photographs so you can review how much tooth length will be revealed and how the left and right sides will balance.

3. Local anaesthesia: A topical numbing gel followed by gentle local anaesthesia ensures the treatment area is numb before any contouring begins.

4. Precision tissue reshaping: For soft-tissue cases, the dentist guides the laser handpiece along the marked contour, sculpting the margin in sub-millimetre increments while sealing tiny blood vessels. For osseous crown lengthening, a microsurgical approach adjusts the bone level and repositions the gum with fine sutures.

5. Post-procedure review: We check symmetry when you smile and speak, apply a soothing oral gel if indicated, and walk you through your home-care kit.

Sequencing gum contouring with porcelain veneers

Many international patients combine gum contouring with porcelain veneers or laser gum depigmentation. When both gum and tooth work are planned, sequence and healing time are critical:

• Minor laser contouring (1–2 mm soft tissue only): In selected cases with stable bone clearance, tooth preparation and digital scanning for veneers may proceed during the same trip once the margin settles over several days, subject to your dentist's clinical judgment.

• Extensive contouring or surgical crown lengthening: The gum margin continues to mature for 6 to 12 weeks after bone reshaping. Placing final veneer margins before the gum has stabilized risks exposing the veneer edge later. In these cases, we recommend staging treatment across two visits or using long-term provisional restorations while the tissue matures. See our Bangkok veneer treatment timeline guide for trip-planning details.

Recovery timeline and daily aftercare

• First 48 hours: Expect mild tenderness or a slight warm sensation along the gumline, manageable with standard over-the-counter pain relief prescribed by your dentist. Choose cool or lukewarm soft foods (yogurt, soup, scrambled eggs, smoothies).

• Days 3 to 7: Avoid spicy, acidic, crunchy, or seed-heavy foods that can irritate the healing margin. Use the prescribed antimicrobial mouth rinse or warm saltwater rinse gently without vigorous swishing. Brush the biting surfaces of the teeth with an ultra-soft brush while avoiding direct scrubbing on the treated gum edge until advised.

• Smoking & alcohol: Avoid tobacco and alcohol for at least 7 days, as both constrict gingival blood flow and delay epithelial healing.

Indicative costs and travel planning in Bangkok

Because gum contouring ranges from a single-tooth symmetry adjustment to a full-arch surgical crown lengthening, exact fees are confirmed after your clinical examination and X-ray review.

Frequently asked questions

Will my gums grow back after gum contouring?

Whether gum tissue rebounds depends on whether the underlying bone level (biological width) was properly assessed. When excess soft tissue is removed within safe biological limits, or when the bone crest is adjusted via crown lengthening where needed, the reshaped margin remains stable long term. If a laser is used alone where bone reduction was actually required, tissue rebound is more likely, which is why probing and X-rays come first at COSDENT.

Is gum contouring painful?

Local anaesthesia numbs the gums completely before treatment starts, so you should not feel sharpness during the procedure. Afterward, soft-tissue laser contouring typically causes mild tenderness for 2 to 4 days, while surgical crown lengthening involves a 7 to 14 day healing period with sutures.

Can gum contouring fix receding gums?

No. Gum contouring removes or repositions excess tissue where the gum covers too much of the tooth. If your gums have receded and exposed the root surface, you need a periodontal assessment to discuss root coverage, connective tissue grafting, or restorative protection.

How many days should I stay in Bangkok for gum contouring?

For standalone soft-tissue laser gum contouring, a 3 to 5 day stay in Bangkok allows time for your consultation, procedure, and a post-treatment check before flying home. If surgical crown lengthening with sutures is required, allow 7 to 14 days so sutures can be reviewed and removed safely.

How do I start my assessment?

You can contact COSDENT Smile Design via WhatsApp, LINE, or our online form with clear close-up smile photos for a preliminary discussion with our dental team, followed by an in-clinic examination in Bangkok.

Clinical suitability, treatment method, healing timelines and fees depend on individual anatomy and are confirmed after an in-person dentist assessment.
