Gum contouring — also called gum reshaping, gingival contouring, or cosmetic crown lengthening — is a cosmetic dental procedure in which a small amount of excess gum tissue is carefully removed or repositioned to reveal more of the natural tooth surface and create a more symmetrical, proportionate gumline. The result is teeth that appear longer, more evenly sized, and better proportioned — without any change to the teeth themselves.
Gum contouring addresses two primary cosmetic concerns. Excessive gum display (a gummy smile): when a large amount of gum tissue is visible above the teeth when smiling — making teeth appear short or stubby — contouring removes the excess to expose a greater portion of the natural crown, with the ideal ratio showing roughly 1–2mm of gum tissue above the upper teeth when smiling widely. Uneven or asymmetric gumline: when the gumline dips lower on some teeth and higher on others, it creates visual inconsistency even when the teeth themselves are straight and healthy — contouring corrects the gumline level tooth by tooth, creating symmetry across the full smile.
A gummy smile or uneven gumline can stem from genetics (some patients naturally have more gum tissue covering their teeth), certain medications (particularly some antihypertensives and anticonvulsants) that cause gum overgrowth, abnormal tooth eruption where teeth didn't fully emerge from the gumline, lip hyperactivity where the upper lip lifts higher than average when smiling, or post-orthodontic tissue that didn't fully remodel after braces or Invisalign.
Your Boca dentist performs a clinical examination of your gum tissue, teeth, and bone structure. We evaluate the cause of your gummy smile or gumline asymmetry, assess periodontal health, and determine how much tissue reshaping is appropriate and what the result will look like. If veneers are planned alongside gum contouring, the contouring is designed in coordination with the final veneer proportions.
Using photographs and digital imaging, your dentist can show you a preview of how your smile will look with the gumline corrected. You can evaluate the proposed gumline height and symmetry before treatment begins.
The treatment area is fully numbed with local anesthesia. Patients should feel pressure and mild vibration during the procedure but no pain. For anxious patients, nitrous oxide (laughing gas) sedation is available at select Boca locations — ask when booking.
Your dentist precisely removes and/or reshapes the excess gum tissue, tooth by tooth, using a soft-tissue technique that ensures clean margins and predictable healing. The procedure reveals more of the natural tooth crown while maintaining the biological width — the healthy band of gum tissue that protects the underlying bone.
After the procedure, the treated tissue will be slightly swollen and tender for several days. Your dentist provides specific aftercare instructions: a soft diet for several days, careful brushing technique around the area, and any prescribed rinse or medication. Full soft-tissue healing typically occurs within 1–2 weeks, though final gum position stabilizes over 4–6 weeks.
A follow-up appointment at 2–4 weeks allows your dentist to confirm healing is progressing normally and the gumline is settling to its intended position. If veneer placement follows gum contouring, it is typically scheduled after the gumline has fully stabilized (4–6 weeks post-procedure).
Procedure: a single appointment, 30–120 minutes depending on the extent of contouring. Soft-tissue healing: 1–2 weeks. Final gumline stabilization: 4–6 weeks. Veneer placement (if applicable): after the gumline has fully stabilized.
Gum contouring creates the appearance of longer, more proportionate teeth — without veneers, without drilling, without changing the teeth at all. The transformation comes entirely from optimizing the frame around your teeth.
Most gum contouring cases are done in one visit. Unlike multi-step cosmetic procedures, the reshaping is immediate — you leave with a dramatically improved gumline the same day.
Most patients return to normal activities within 24–48 hours. Soft-tissue healing is typically complete within 1–2 weeks. This is one of the least disruptive cosmetic dental procedures available.
Gum tissue does not regenerate to its pre-treatment position after contouring. Unlike whitening, which fades, or bonding, which wears, gum contouring delivers a lasting structural improvement to your smile architecture.
Gum contouring before veneer placement allows your cosmetic dentist to design veneers to the final gumline — ensuring perfect proportions and symmetry in the finished result. Skipping gum contouring when it's indicated can compromise the aesthetics of even the finest porcelain veneers.
