Board-certified periodontist Dr. Chanook David Ahn performs expert crown lengthening surgery at The Loft Dental Studio in Costa Mesa, just a 15-minute drive from Huntington Beach. Precise bone recontouring and soft tissue reshaping for both functional restorations and cosmetic gummy smile correction.
Crown lengthening is a periodontal procedure designed to expose more of a tooth's natural structure by removing gum tissue and, when necessary, recontouring the underlying alveolar bone. Huntington Beach residents seeking this specialized surgery benefit from the expertise of a board-certified periodontist who performs both functional and cosmetic crown lengthening on a daily basis. The procedure addresses two distinct clinical needs: functional crown lengthening creates adequate tooth structure for a dentist to place a well-sealed crown, bridge, or filling, while cosmetic crown lengthening corrects the appearance of a gummy smile by revealing the full natural length of the teeth.
The biological principle behind crown lengthening centers on what periodontists refer to as the biologic width, a zone of approximately 2 to 3 millimeters that the body naturally maintains between the crest of the alveolar bone and the margin of the gum tissue. When a tooth fractures below the gum line or when excessive tissue conceals the teeth, this biologic width must be surgically re-established. Simply trimming gum tissue without modifying the bone is a common shortcut that produces temporary results. The tissue regrows because the body rebuilds it to satisfy the biologic width requirement. True crown lengthening, as performed by Dr. Ahn, modifies both the bone and the soft tissue so the result is stable and lasting.
For patients traveling from Huntington Beach, understanding the difference between a gingivectomy and a genuine crown lengthening procedure is important. A gingivectomy removes only soft tissue and may be offered by general dentists using a laser or scalpel. It works for minor cosmetic improvements where no bone modification is needed, but it is not a substitute for crown lengthening when the bone level is too high or when a stable, long-term outcome is required.
A board-certified periodontist has completed three additional years of surgical residency training beyond dental school, focused entirely on the hard and soft tissues surrounding teeth. This distinction matters enormously for crown lengthening because the procedure requires precise bone recontouring, careful flap management, and a thorough understanding of tissue healing biology. Dr. Chanook David Ahn completed his periodontal training at Yale, one of the most rigorous programs in the country, and has placed over 5,000 dental implants, a testament to his depth of experience with bone and tissue surgery.
Board certification through the American Board of Periodontology requires passing both a written examination and an oral defense of clinical cases. It demonstrates that a periodontist has not only completed advanced training but has also proven mastery of the discipline through independent examination. Fewer than half of all periodontists hold board certification, making Dr. Ahn part of an elite group of specialists.
The Specialist Advantage: When a general dentist performs a gingivectomy, the soft tissue is trimmed but the bone remains at its original level. Within weeks to months, the tissue often grows back to its pre-surgical position because the biologic width has not been addressed. Dr. Ahn raises a tissue flap, precisely reshapes the bone to the planned level, and then repositions the tissue to create a permanent new gum line. Huntington Beach patients who make the 15-minute drive to see a specialist avoid the cycle of repeated procedures that fail to deliver lasting results.
Crown lengthening also requires aesthetic judgment, particularly for cosmetic cases. The gum line must follow a natural, harmonious curve where the central incisors and canines appear slightly longer than the lateral incisors. The tissue margins must be symmetric from left to right. Dr. Ahn evaluates each patient's smile dynamics, lip line, tooth proportions, and facial symmetry to plan a gum line that looks naturally beautiful rather than surgically altered.
Functional crown lengthening is the most commonly performed form of this procedure and is often medically necessary. It is indicated when a tooth has fractured, decayed, or worn down to a level where insufficient structure remains above the gum line for a general dentist to place a crown with a proper seal. Without adequate exposed tooth, a crown cannot grip the tooth reliably, leading to loosening, bacterial leakage beneath the restoration, and ultimately failure of the crown.
In many cases, a tooth that has been recommended for extraction by another provider can be saved through crown lengthening followed by a well-designed restoration. Dr. Ahn evaluates root length, remaining bone support, and overall prognosis to determine whether the tooth is a candidate for preservation. Saving a natural tooth, when possible, is almost always preferable to extraction and implant replacement both biologically and financially.
A gummy smile is a condition where excessive gum tissue covers too much of the teeth, making them appear short, square, or disproportionate even though the teeth underneath may be perfectly normal in size. Many Huntington Beach patients who are self-conscious about showing too much gum when they smile do not realize that a straightforward surgical procedure can dramatically improve their smile aesthetics in a single visit.
The most common cause of a gummy smile is a condition called altered passive eruption. During normal dental development, the gum tissue is supposed to migrate toward the root as the teeth fully erupt into position. In some individuals, this migration does not complete, leaving excess tissue draped over the teeth into adulthood. The teeth are fully formed beneath the tissue but remain partially hidden.
Cosmetic crown lengthening addresses the smile zone, typically the six to ten teeth visible when smiling. Dr. Ahn carefully plans the new gum line position for each tooth, accounting for ideal tooth proportions (the width-to-length ratio should be approximately 75 to 80 percent), symmetry between corresponding teeth on the left and right sides, and the natural scalloped contour where the gum dips lower between teeth and rises slightly over the center of each tooth. The bone is reshaped to support this new gum position, ensuring the result is permanent.
Cosmetic crown lengthening is one of the most gratifying procedures I perform. Many patients come in feeling embarrassed about their smile and leave with a completely transformed appearance after a single procedure. The key is precision planning. I evaluate the smile from multiple angles, assess lip dynamics, and measure tooth proportions to design a gum line that looks like it has always been there. The bone recontouring is what makes the result permanent, and it requires a periodontist's training to perform with the accuracy these cases demand.
Understanding the process helps Huntington Beach patients feel prepared and confident before their appointment. Here is what happens during crown lengthening at The Loft Dental Studio.
Your first visit involves a comprehensive examination including digital X-rays or a CBCT 3D scan to evaluate bone levels around the affected teeth. For functional cases, Dr. Ahn coordinates with your referring dentist to understand the restoration requirements and ensure the surgical plan supports the final crown design. For cosmetic cases, he evaluates your smile line, lip dynamics, tooth dimensions, and facial proportions to map out the ideal gum line position for each tooth.
Crown lengthening is performed under local anesthesia with optional sedation. Dr. Ahn makes precise incisions in the gum tissue and elevates a flap to expose the underlying bone. Using microsurgical instruments, he reshapes the alveolar bone around each tooth to the planned level, removing just enough to establish proper biologic width, typically about 3 millimeters between the new bone crest and the intended gum margin. The tissue is then repositioned and secured with fine sutures. The procedure takes 45 to 90 minutes depending on the number of teeth involved.
Dr. Ahn uses Platelet-Rich Fibrin therapy derived from a small sample of your own blood. PRF concentrates natural growth factors and places them directly at the surgical site, promoting faster soft tissue healing, reduced inflammation, and improved post-operative comfort. This biological approach to healing support is included at no additional charge.
Crown lengthening costs depend on the type of procedure, the number of teeth treated, and the complexity of bone recontouring required. The Loft Dental Studio provides detailed treatment estimates after your evaluation so there are no financial surprises.
Functional crown lengthening is frequently covered by PPO dental insurance plans because it is medically necessary for tooth restoration. Coverage typically ranges from 50 to 80 percent. Cosmetic crown lengthening is generally considered elective. We accept most major PPO plans including Delta Dental, Cigna, MetLife, Guardian, Aetna, United Healthcare, and Blue Cross Blue Shield. Our team verifies your benefits before treatment. Financing through CareCredit and FSA/HSA funds are also accepted. Visit our Insurance & Payment page for details.

Crown lengthening is a surgical procedure that involves reshaping both bone and gum tissue. The difference between having it performed by a board-certified periodontist versus a general dentist is significant. Dr. Chanook David Ahn completed his periodontal residency at Yale and has performed thousands of surgical cases. A general dentist may offer a gingivectomy (soft tissue trimming), but without bone recontouring the tissue frequently grows back. A 15-minute drive to see a specialist who delivers permanent, predictable results is well worth the trip compared to repeated procedures that fail to hold.
Most patients can return to light physical activities within 3 to 5 days after crown lengthening. However, vigorous activities like surfing, which involve exposure to salt water, strong sun, and elevated heart rate, should be avoided for at least 7 to 10 days. Salt water can irritate healing surgical tissue, and increased blood pressure from physical exertion may cause bleeding at the surgical site. Dr. Ahn provides personalized recovery guidelines at your post-operative appointment and clears you for full activity once healing is progressing well, typically at the 10 to 14 day mark.
The Loft Dental Studio offers multiple sedation options to ensure your comfort during crown lengthening. All procedures are performed under local anesthesia for complete numbness. Beyond that, patients can choose nitrous oxide (laughing gas) for mild relaxation, oral sedation for moderate anxiety reduction, or IV sedation for deeper relaxation where you remain conscious but have little memory of the procedure. Dr. Ahn discusses your comfort preferences during the consultation and recommends the best option based on the complexity of your case and your personal anxiety level.
Crown lengthening typically requires 3 appointments. The first is a consultation where Dr. Ahn examines your teeth, takes digital X-rays or a CBCT scan, and develops a treatment plan. The second appointment is the surgical procedure itself, which takes approximately 45 to 90 minutes depending on the number of teeth involved. The third appointment is a follow-up visit 7 to 10 days later for suture removal and healing evaluation. Additional follow-up visits may be scheduled at 4 to 6 weeks and again at 3 months to confirm tissue maturation before your general dentist places the final restoration.
Functional crown lengthening typically costs $1,200 to $2,500 per tooth, while cosmetic crown lengthening for gummy smile correction ranges from $2,500 to $5,000 for the full smile zone. Functional crown lengthening is often covered by PPO dental insurance because it is medically necessary to enable tooth restoration, with coverage typically ranging from 50 to 80 percent. Cosmetic crown lengthening is generally considered elective and is not covered. The Loft Dental Studio accepts most major PPO plans including Delta Dental, Cigna, MetLife, and Aetna, and offers CareCredit financing and accepts FSA/HSA funds.
