A gummy smile — where excessive gum tissue makes your teeth appear short — is one of the most common cosmetic dentistry concerns patients bring to our office. The good news: a periodontist can correct it, often in a single procedure. At The Loft Dental Studio, Dr. Ahn uses crown lengthening, laser gum contouring, and coordinated treatment planning with our prosthodontist to deliver natural-looking, lasting results.
What Causes a Gummy Smile?
Not all gummy smiles have the same cause, and identifying the specific reason is essential for choosing the right treatment. The most common causes include:
- Excess gum tissue covering too much of the tooth surface: This is the most frequent cause. The gum tissue extends too far down the tooth, making teeth appear shorter than they actually are underneath.
- Short clinical crowns: The visible portion of the tooth is genuinely shorter than average, creating teeth that appear small and square rather than proportionally shaped.
- Hyperactive upper lip: A lip that rises significantly higher than normal when smiling, exposing more gum tissue than typical. The gum tissue itself may be completely normal.
- Excessive vertical growth of the upper jaw: A skeletal cause where the upper jawbone grew longer than typical during development, resulting in more gum display when smiling.
- Altered passive eruption: During normal development, gum tissue is supposed to recede to its final position as teeth fully emerge. When this process does not complete, the gum tissue remains in its juvenile position, covering more tooth than it should. This is one of the most underdiagnosed causes of a gummy smile.
Dr. Ahn diagnoses the underlying cause during a comprehensive evaluation that includes clinical examination and CBCT 3D imaging. Getting the diagnosis right is what separates a predictable outcome from a disappointing one — the treatment that works for excess gum tissue will not address a skeletal discrepancy.
How Crown Lengthening Fixes a Gummy Smile
Crown lengthening is the definitive treatment for gummy smiles caused by excess gum tissue and short clinical crowns. The procedure involves reshaping gum tissue — and sometimes bone — to expose more natural tooth structure, creating a more proportional tooth-to-gum ratio.
Dr. Ahn is a board-certified periodontist, which means this procedure falls squarely within his specialty training. Crown lengthening requires precise understanding of biological width, tissue attachment levels, and bone architecture — this is not a procedure that general dentists typically perform. The margin between an excellent result and an uneven one is measured in fractions of millimeters.
The procedure can be performed on a few teeth or across the entire smile zone. Healing is straightforward — most patients return to work within a day or two, and the correction is permanent once healed.
Laser Gum Contouring vs. Traditional Surgery
Laser gum contouring uses focused laser energy to precisely reshape gum tissue. The laser cauterizes as it works, resulting in minimal bleeding, less swelling, and faster healing. Most patients are back to normal activities within one to two days with only mild tenderness managed by over-the-counter pain medication.
Traditional scalpel surgery remains the appropriate choice when more extensive reshaping is needed — particularly when bone recontouring is part of the treatment plan. For cases involving altered passive eruption where the bone level is too high, the periodontist must recontour bone to establish correct biological width. Recovery typically takes one to two weeks.
Dr. Ahn uses both techniques depending on the case. CBCT 3D imaging helps determine which approach is appropriate by revealing the exact relationship between gum tissue, bone, and tooth structure — information that determines whether laser contouring alone will produce a lasting result or whether bone modification is necessary.
Combining Gum Contouring with Veneers — The Two-Specialist Approach
Many gummy smile patients also want veneers or other cosmetic improvements. When both gum contouring and veneers are part of the plan, the sequence and coordination between specialists makes all the difference.
Dr. Ahn performs the gum contouring first to establish the proper gum line. After healing — typically four to six weeks — Dr. Lu, our board-certified prosthodontist, designs and places porcelain veneers on the properly exposed teeth. Because the gum architecture has already been finalized, Dr. Lu can create veneers with precise proportions and natural emergence profiles that complement the new gum line.
This two-specialist approach under one roof is rare. Most offices would refer you to a separate periodontist for the gum work, then coordinate remotely for the veneer phase. Having both specialists in the same practice means seamless communication and a cohesive cosmetic dentistry outcome that addresses both the frame (gum tissue) and the picture (teeth) together.
Gummy Smile Correction Cost
We believe in transparent pricing so patients can plan accordingly:
- Gum contouring or crown lengthening: $500 to $3,000 depending on how many teeth are involved and whether bone recontouring is required.
- Porcelain veneers (if combined): Add $1,000 to $2,500 per tooth depending on the number of teeth and complexity of the case.
- Insurance coverage: Some plans cover crown lengthening when performed for restorative purposes — for example, when insufficient tooth structure is exposed for a proper crown fit.
- Financing: The Loft Dental Studio offers financing options. Our team can discuss available plans during your consultation.
Our Costa Mesa office is located at 3151 Airway Ave, Suite F-103. We welcome patients from throughout Orange County for gummy smile consultations.
Frequently Asked Questions
Can a gummy smile be fixed permanently?
Yes. Crown lengthening performed by a board-certified periodontist like Dr. Ahn is a permanent correction. The procedure removes or reshapes excess gum tissue and, when necessary, bone tissue to expose more tooth structure. Once healed, the results are lasting. In some cases, patients combine gum contouring with veneers for a complete smile transformation.
Is gummy smile correction painful?
The procedure is performed under local anesthesia, so patients feel no pain during treatment. Post-procedure discomfort is typically mild — most patients manage it with over-the-counter pain medication like ibuprofen. Patients who receive laser gum contouring often report minimal discomfort and return to normal activities within one to two days. Traditional crown lengthening that involves bone recontouring may require one to two weeks of recovery.
How long does it take to see results from gummy smile correction?
You will see an immediate difference right after the procedure, though some swelling is normal in the first few days. Final results are visible within two to four weeks as the tissue heals. If you are combining gum contouring with veneers, Dr. Lu typically places the veneers four to six weeks after the gum surgery to allow complete healing.
