Board-certified periodontist Dr. Chanook David Ahn serves all of Orange County from The Loft Dental Studio in Costa Mesa. Precision bone recontouring and soft tissue reshaping for both functional restorations and cosmetic gummy smile correction.
Crown lengthening is a periodontal procedure in which a board-certified periodontist removes gum tissue and reshapes the supporting bone around one or more teeth to reveal additional tooth structure above the gum line. Orange County patients seek this surgery for two primary reasons. Functional crown lengthening creates the clearance a general dentist needs to seat a crown, bridge, or filling on a tooth that has broken or decayed near or beneath the gum margin. Cosmetic crown lengthening sculpts the gum line to correct a gummy smile, revealing the full natural length of teeth that appear short because excess tissue hides them.
Both versions of the procedure share the same surgical principles. The periodontist raises a gum flap, recontours the alveolar bone to a carefully planned level, and repositions the tissue at its new margin. The reason bone recontouring matters is a biological rule called the biologic width: the body insists on maintaining roughly 2 to 3 millimeters of soft tissue attachment between the bone crest and the visible gum edge. If a surgeon only trims gum tissue without lowering the bone, the tissue regrows to restore that distance within weeks. Proper crown lengthening respects this biology, which is why the results are permanent and predictable when performed by a trained periodontist.
Throughout Orange County, general dentists refer patients to periodontists specifically for crown lengthening because it requires advanced surgical skill in both soft tissue management and bone recontouring. Dr. Chanook David Ahn at The Loft Dental Studio in Costa Mesa has performed thousands of these procedures and coordinates closely with referring dentists across Irvine, Newport Beach, Anaheim, Huntington Beach, Santa Ana, and the broader OC region to ensure seamless treatment outcomes.
Orange County has many dental providers, but only a small percentage hold board certification from the American Board of Periodontology. Board certification is a voluntary credential that goes beyond the three-year surgical residency every periodontist completes. It requires passing a comprehensive written examination and an oral case-defense examination in which the periodontist presents treated cases to a panel of examiners. Dr. Ahn earned his board certification after completing his periodontal residency at Yale, where he trained under some of the country's leading educators in bone biology and implant surgery.
The distinction between a board-certified periodontist and other providers who may offer crown lengthening becomes clear in the surgical approach. A general dentist performing a laser gingivectomy addresses only the soft tissue. The gum tissue may look improved for several weeks, but the underlying bone has not been repositioned, and the biologic width forces tissue regrowth. A board-certified periodontist like Dr. Ahn raises a full-thickness flap, visualizes the bone directly, and uses precision rotary and hand instruments to recontour the alveolar ridge to the exact level the treatment plan demands. The tissue is then sutured to its new position, and because the bone now supports the new margin, the result remains stable for years.
What Board Certification Means for Your Outcome: A board-certified periodontist has demonstrated surgical competency in front of independent examiners. This credential represents the highest level of validation in the specialty of periodontics. When your general dentist refers you to a board-certified periodontist for crown lengthening, they are ensuring your procedure is performed by someone who has proven mastery of the bone and tissue surgery your case requires.
Understanding each phase of the procedure helps Orange County patients prepare with confidence. Here is how Dr. Ahn approaches crown lengthening at The Loft Dental Studio.
Every case begins with a clinical examination and digital imaging. Dr. Ahn takes measurements of the existing tooth structure above and below the gum line, evaluates bone levels on X-rays or CBCT scans, and reviews the restorative or cosmetic goals with the patient and referring dentist. For cosmetic cases, he assesses lip dynamics, tooth proportions, and gum symmetry across the entire smile zone. This planning phase determines exactly how much bone and tissue need to be repositioned at each tooth to achieve the desired result while maintaining healthy biological dimensions.
Crown lengthening is performed under local anesthesia, which provides complete numbness throughout the procedure. Patients who prefer deeper relaxation can choose IV sedation, oral sedation, or nitrous oxide. Dr. Ahn's team monitors patients continuously during sedation to ensure comfort and safety. Most patients who choose sedation report little to no memory of the procedure.
Dr. Ahn makes precise incisions and elevates the gum tissue to expose the underlying bone. He then uses microsurgical instruments to reshape the bone to the level determined during treatment planning. The key measurement is establishing approximately 3 millimeters of clearance between the new bone crest and the intended gum margin, which satisfies the biologic width and prevents tissue rebound. For cosmetic cases addressing multiple teeth, Dr. Ahn ensures the bone recontouring is perfectly symmetric so the final gum line curves naturally from tooth to tooth.
Once bone recontouring is complete, the gum flap is repositioned at the new, lower level and secured with fine sutures. Dr. Ahn contours the tissue carefully to create clean, defined gum margins. PRF membranes derived from the patient's own blood are placed at the surgical site to deliver concentrated growth factors that speed tissue healing and reduce inflammation.
For functional cases, Dr. Ahn sends a detailed surgical report to your general dentist that includes the amount of tooth structure now exposed, the healing timeline, and the optimal window for final restoration placement. This coordination ensures the crown or bridge your dentist places integrates perfectly with the surgically repositioned tissue.

Crown lengthening addresses a specific set of clinical and cosmetic situations. Understanding whether the procedure applies to your case helps you make an informed decision when consulting with Dr. Ahn.
Many teeth that have been recommended for extraction by a general dentist can actually be preserved with crown lengthening. If the root is healthy, the bone support is adequate, and there is no vertical root fracture, exposing more tooth structure through crown lengthening followed by a well-made crown can give that tooth another decade or more of function. I always evaluate the full picture before recommending extraction, because preserving a natural tooth is almost always preferable to replacing it with an implant when the prognosis supports it.

Functional crown lengthening is medically necessary when a tooth has fractured, decayed, or worn below the gum line and your general dentist cannot place a crown or restoration without more exposed tooth structure. The periodontist removes bone and gum tissue to reveal enough tooth for the restoration to seat properly. Cosmetic crown lengthening addresses a gummy smile where excess tissue makes teeth look short or uneven. Dr. Ahn reshapes the gum line and underlying bone across the smile zone to create balanced, symmetrical tooth proportions. Functional procedures are often partially covered by PPO dental insurance, while cosmetic procedures are typically considered elective.
Most Orange County patients return to normal daily activities within 1 to 2 days after crown lengthening. Swelling and mild discomfort peak around days 2 to 3 and resolve steadily over the first week. Sutures are removed at 7 to 10 days. A soft diet is recommended for the first week to protect the surgical site. Full tissue maturation takes 3 to 6 months, at which point the gum tissue has settled into its permanent position. For functional cases, your dentist can typically proceed with the final crown or restoration after 6 to 8 weeks. Dr. Ahn uses PRF therapy to accelerate healing and reduce post-operative discomfort.
Functional crown lengthening is frequently covered by PPO dental insurance plans because it is classified as a medically necessary surgical procedure that enables tooth restoration. Coverage typically ranges from 50 to 80 percent of the allowed amount, depending on your plan's periodontal surgery benefits. Cosmetic crown lengthening for gummy smile correction is generally not covered because it is considered elective. The Loft Dental Studio accepts most major PPO plans including Delta Dental, Cigna, MetLife, Guardian, Aetna, United Healthcare, and Blue Cross Blue Shield.
