Gum contouring reshapes excess or uneven gum tissue to create a balanced, symmetrical smile that complements the teeth. The procedure removes small amounts of gingival tissue, exposing more of the natural tooth crown and correcting disparities in gum height that make teeth appear short, square, or misaligned. For adults in Laguna Niguel, Aliso Viejo, and across South Orange County who feel their smile is dominated by their gums, gum contouring offers a precise, minimally invasive path to improved facial aesthetics.

Understanding gum contouring begins with recognizing how gum tissue shapes the smile. The cosmetic dentistry treatments offered at Aesthetic Dental Designs address both the teeth and the supporting tissues that frame them. Gum contouring often complements smile makeover planning, and the dental crowns and cosmetic dentistry guide provide additional context on how individual treatments combine into complete smile design.

Key Takeaways (TL;DR)
- Gum contouring removes excess gingival tissue to expose more tooth structure: The procedure corrects a gummy smile or uneven gum line by reshaping the tissue that frames the teeth.
- Laser techniques offer precision with minimal bleeding: Diode and Er,Cr:YSGG lasers contour soft tissue with less discomfort and faster healing than traditional scalpel methods.
- Gum health must be stable before contouring begins: Active gum disease requires treatment first, because contouring inflamed tissue produces unpredictable results.
- Recovery takes one to two weeks for initial healing: Most patients return to normal activities the same day, with mild sensitivity and a soft diet for several days.
- Crown lengthening addresses both gum tissue and bone: When teeth appear short because of bone coverage, the procedure removes bone in addition to gingival tissue.
What Is Gum Contouring and How Does It Reshape a Smile?
Gum contouring is a cosmetic dental procedure that removes or reshapes gingival tissue to create a more balanced relationship between the gums and the teeth. Dentists also call this procedure gingivectomy, gum recontouring, or gingival sculpting. The goal is symmetry: an even gum line that exposes a consistent amount of tooth structure across the smile.
A smile with more than 2 millimeters of exposed gum tissue when smiling is commonly described as a gummy smile [citation:14]. Gummy smiles appear in roughly 10.5 percent to 29 percent of the population and affect women more often than men [citation:14]. Gum contouring directly addresses this excess tissue.
The symmetry principle: A balanced smile has gum tissue that follows a gentle curve across the central incisors, canine teeth, and premolars. When one tooth’s gum margin sits higher or lower than its neighbor, the eye reads the disparity as a flaw in the tooth itself, even when the tooth is perfectly healthy.
Excess Gum Tissue and the Gummy Smile
Excess gum tissue covers more of the tooth crown than is aesthetically ideal. The condition has several origins: altered passive eruption during childhood, where the gums fail to recede to their normal position after tooth eruption; gingival overgrowth from certain medications; or naturally thick, fibrotic gingival tissue [citation:14].
Uneven Gum Line and Tooth Proportion
An uneven gum line creates the illusion that teeth differ in length when they are actually the same size. Asymmetrical gum margins also disrupt the smile arc, the gentle curve formed by the incisal edges of the upper teeth. Cosmetic dentists evaluate tooth proportion through digital smile design, measuring crown width-to-height ratios and comparing gingival margins across the midline [citation:3].
What Causes an Uneven or Excess Gum Line?
An uneven or excess gum line develops from a combination of genetic, developmental, and acquired factors. Identifying the cause determines whether gum contouring alone will produce a stable result or whether underlying conditions require treatment first.
Genetics and Natural Gum Thickness
Genetics determine baseline gingival thickness and the position of the gum margin on each tooth. Some patients inherit a thick periodontal phenotype with a naturally high gum line that covers more tooth structure. Others have a thin phenotype with scalloped, delicate tissue that may recede rather than overgrow [citation:17].
Gum Disease and Recession
Gum disease damages the tissues and bone that support teeth. Gingivitis, the early stage, produces red, swollen gums that bleed easily but remains reversible with professional cleaning and improved home care [citation:4][citation:6]. Periodontitis, the advanced stage, involves irreversible bone loss and can cause gums to pull away from teeth, creating recession rather than excess tissue [citation:5][citation:12].
About 4 in 10 U.S. adults 30 years or older had some level of periodontitis in 2009–2014, according to CDC data [citation:12]. Because periodontitis affects the bone and connective tissue that support teeth, gum contouring in a patient with active disease produces unstable results. The infection requires treatment first.
Medications, Hormones, and Gum Enlargement
Certain medications cause gingival overgrowth as a side effect. The National Institute of Dental and Craniofacial Research notes that some prescription and over-the-counter medications can reduce saliva flow or cause abnormal overgrowth of gum tissue [citation:13]. Hormonal changes during pregnancy or menopause also increase gum sensitivity and inflammation, which may exacerbate tissue enlargement [citation:12].
Tooth Wear and Compensatory Eruption
Teeth that wear down from bruxism or acid erosion continue to erupt slowly to maintain contact with opposing teeth. This compensatory eruption carries the gum tissue downward with it, making the clinical crowns appear shorter over time. The gum line may appear uneven when wear affects some teeth more than others.
What Techniques Do Dentists Use for Gum Contouring?
Dentists perform gum contouring with lasers, scalpels, or electrosurgical units. The choice of technique depends on the amount of tissue to be removed, whether bone requires reshaping, and the patient’s healing profile.
Laser Gum Contouring
Laser gum contouring uses diode or erbium lasers to remove gingival tissue with precision. A 2022 randomized controlled trial compared Er,Cr:YSGG laser-assisted esthetic crown lengthening using open-flap and flapless approaches. The study found that both techniques achieved predictable outcomes with mean tissue rebound of only 0.25 to 0.26 millimeters after nine months [citation:17].
Clinical studies comparing laser and scalpel techniques for soft tissue crown lengthening have assessed patient comfort and gingival margin stability. The evidence supports laser use for reduced bleeding, less postoperative discomfort, and precise tissue removal [citation:10].
Scalpel and Electrosurgery Techniques
Traditional gingivectomy uses a scalpel to excise excess tissue. The technique provides excellent control and direct visualization but produces more bleeding and requires sutures in some cases. Electrosurgery uses a fine tipped instrument that cuts and coagulates simultaneously. Both methods remain viable when a laser is unavailable or when the tissue thickness favors a blade approach.
Crown Lengthening for Restorative Needs
Crown lengthening removes both gum tissue and bone to expose more tooth structure. Dentists perform this procedure when teeth appear short because bone covers the crown, or when a tooth needs more exposed surface for a crown or filling. Esthetic crown lengthening specifically aims to improve appearance by correcting altered passive eruption and creating symmetrical gingival margins [citation:3][citation:17].
Biological width matters: Dentists must preserve at least 3 millimeters of tissue between the restoration margin and the bone crest. Violating this biological width triggers chronic inflammation, bone loss, and gum recession around the restored tooth.
Who Is a Candidate for Gum Contouring?
Ideal candidates for gum contouring have healthy gum tissue, adequate bone support, and a cosmetic concern related to excess or uneven gingival display. Candidacy depends as much on periodontal stability as on aesthetic goals.
Healthy Gums and Bone Support
The periodontium must be free of active infection before contouring. Dentists measure pocket depths around each tooth using a periodontal probe. Healthy pockets measure between 1 and 3 millimeters; deeper pockets signal periodontal disease requiring treatment [citation:6][citation:13]. Gums that bleed when probed or brushed indicate inflammation that must resolve first.
Cosmetic Goals and Tooth Proportion
Patients who feel their teeth look short, square, or uneven because of gum coverage are candidates for evaluation. Digital smile design helps dentists and patients visualize the proposed gum line before treatment. Measuring the width-to-height ratio of each tooth and comparing gingival margin heights across the smile guides the amount of tissue to remove [citation:3].
When Gum Disease Treatment Comes First
Active periodontitis disqualifies a patient from immediate gum contouring. Scaling and root planing, a deep cleaning below the gumline, removes plaque and tartar from periodontal pockets and smooths root surfaces to help gums reattach [citation:18]. The American Dental Association notes that scaling and root planing benefits patients with chronic periodontitis, which affects 47.2 percent of adults over 30 in the United States [citation:18].
After periodontal treatment, the gums require several weeks to heal and stabilize. Only then can the dentist assess the final gum position and plan contouring accurately.
What Happens During Gum Contouring and Recovery?
Gum contouring proceeds in a single appointment under local anesthesia. The dentist marks the new gum line, removes tissue to the marked level, and shapes the margins for a natural scalloped contour. Healing begins immediately, with noticeable results visible within one to two weeks.
Step-by-Step Procedure
The procedure follows a consistent sequence:
- Anesthesia: Local anesthetic numbs the gums and surrounding tissue. Patients remain awake and comfortable throughout.
- Measurement and marking: The dentist uses a periodontal probe or a pre-made stent to mark the target gum line on each tooth.
- Tissue removal: A laser or scalpel removes excess gingival tissue to the marked level. The dentist sculpts a scalloped margin that follows the natural curve of the smile.
- Contouring and finishing: The margins are refined for smoothness and symmetry. Bleeding is controlled, and the dentist may place a protective dressing in some cases.
- Postoperative instructions: The patient receives care instructions and a follow-up appointment for one to two weeks later.
Healing Timeline and Aftercare
Initial healing takes 7 to 14 days. During this period, patients should:
- Eat soft, cool foods for the first 3 to 5 days
- Avoid spicy, acidic, or crunchy foods that irritate healing tissue
- Brush gently around the treated area, using a soft-bristled brush
- Rinse with a prescribed antimicrobial mouthwash if directed
- Avoid tobacco products, which impair healing and increase infection risk [citation:5]
- Take over-the-counter pain relievers as needed for mild discomfort
The gums may appear red and slightly swollen for the first week. As healing progresses, the tissue tightens and the new gum line settles into its final position. Tissue rebound, the slight regrowth of gum tissue after surgery, averages less than 0.3 millimeters with laser techniques [citation:17].
Results and Longevity
Gum contouring results are permanent when the underlying cause of excess tissue is developmental or genetic. Gingival tissue does not regrow to its original position after laser or surgical removal. If the excess tissue resulted from a medication that the patient continues to take, overgrowth may recur over time.
Patients who maintain good oral hygiene and attend regular dental cleanings preserve their results indefinitely. Gum recession from periodontal disease or aggressive brushing can alter the gum line in the years after contouring, which is one reason periodic professional monitoring matters.
Benefits and Limitations of Gum Contouring
Gum contouring delivers immediate aesthetic improvement with a single procedure and minimal downtime. Patients see more of their natural tooth structure, which makes teeth appear longer, more proportional, and better aligned even when their position has not changed.
Benefits
- Immediate visual improvement in smile symmetry
- Single-appointment procedure for most cases
- Minimal discomfort with laser techniques
- Permanent results when underlying cause is stable
- No effect on tooth structure itself
Limitations
- Requires healthy periodontal tissue
- Does not correct bone-level asymmetry without crown lengthening
- Medication-induced overgrowth may recur
- Cannot reposition teeth or close spaces
- Gum recession from disease may alter results long-term
Frequently Asked Questions
Does gum contouring hurt?
Gum contouring causes minimal discomfort because the dentist anesthetizes the treatment area before starting. Patients report mild soreness for a few days after the procedure, managed with over-the-counter pain relievers. Laser techniques produce less discomfort than scalpel surgery because the laser seals nerve endings and blood vessels as it cuts [citation:10].
How long does gum contouring take?
Gum contouring takes 30 minutes to one hour for a typical cosmetic case involving the front six teeth. More extensive crown lengthening or treatment spanning both arches may require additional time or multiple appointments. Most patients return to work or normal activities the same day.
Will my gums grow back after contouring?
Gums do not regrow to their original position after laser or surgical contouring. Clinical studies measuring tissue rebound after laser-assisted crown lengthening found average changes of 0.25 to 0.26 millimeters after nine months, which is negligible and often imperceptible [citation:17]. Recurrence is possible only when the original cause, such as a medication that triggers gingival overgrowth, remains active.
Is gum contouring the same as crown lengthening?
Gum contouring and crown lengthening are related but distinct. Gum contouring removes only soft gingival tissue to improve appearance. Crown lengthening removes both gum tissue and bone to expose more tooth structure for cosmetic or restorative reasons. A patient with altered passive eruption, where bone covers the tooth crown, needs crown lengthening rather than gingivectomy alone [citation:3][citation:17].
Can I get gum contouring if I have gum disease?
Gum disease must be treated and resolved before gum contouring. Contouring inflamed or infected tissue produces unpredictable healing and poor aesthetic results. A dentist will assess periodontal pocket depths, bleeding on probing, and bone levels. If periodontitis is present, scaling and root planing or other periodontal therapy comes first [citation:18].
People Also Ask
What is the best treatment for a gummy smile?
Gum contouring works best for gummy smiles caused by excess gingival tissue covering normal bone. Crown lengthening is needed when bone also covers the tooth crown. Botulinum toxin injections address gummy smiles caused by an overactive upper lip muscle [citation:14]. A cosmetic dentist diagnoses the cause before recommending treatment.
How much does gum contouring cost?
Gum contouring costs vary by the number of teeth treated, the technique used, and geographic location. Cost figures for education and research only do not reflect the pricing at any specific practice. Patients should request a personalized estimate during a consultation.
Can gum contouring fix asymmetrical teeth?
Gum contouring corrects asymmetrical gum lines that make teeth appear uneven. When teeth themselves are irregular in size or shape, gum contouring may be combined with composite bonding, veneers, or crowns to achieve symmetry. Digital smile design helps plan the combined treatment [citation:3].
What are the risks of gum contouring?
Risks include bleeding, infection, sensitivity, and uneven healing. Removing too much tissue can expose root surfaces and cause sensitivity. Removing too little leaves asymmetry unresolved. Experienced dentists using digital planning and precise techniques minimize these risks.
Is laser gum contouring better than scalpel?
Laser gum contouring offers advantages in precision, hemostasis, and patient comfort. Clinical studies show comparable gingival margin stability between laser and scalpel techniques [citation:10]. The best technique depends on tissue characteristics and the dentist’s training. Both produce excellent results in skilled hands.

Restoring Smile Symmetry Through Gum Contouring
Gum contouring corrects the tissue framework that shapes how a smile is perceived. The procedure removes excess or uneven gingival tissue, exposing more of the natural tooth crown and creating a balanced gum line that draws attention to the teeth rather than the gums. Laser techniques offer precise tissue removal with minimal bleeding and predictable healing, while crown lengthening addresses bone-level asymmetry for patients whose teeth appear short because of skeletal coverage. For residents of Laguna Niguel, Aliso Viejo, Mission Viejo, Dana Point, and the wider South Orange County area, a consultation with a cosmetic dentist experienced in both soft tissue and restorative treatment ensures the gum line is evaluated as part of the complete smile rather than in isolation.
