Newport Beach residents are just a quick 10-minute drive from expert crown lengthening by Yale-trained, board-certified periodontist Dr. Chanook David Ahn. Whether you need a tooth prepared for a restoration or want to correct a gummy smile, The Loft Dental Studio in Costa Mesa delivers precision results backed by thousands of successful surgical cases.
Crown lengthening is a periodontal surgical procedure designed to expose more of the natural tooth structure by carefully removing gum tissue and reshaping the underlying alveolar bone. Newport Beach patients who are told they need a crown but do not have enough tooth above the gum line, or who feel self-conscious about a gummy smile, benefit from this procedure. Crown lengthening addresses the root cause of these issues by precisely re-establishing the relationship between bone, gum tissue, and tooth, a concept periodontists refer to as the biologic width.
The biologic width is the natural measurement, approximately 2 to 3 millimeters, that the body maintains between the top of the bone and the edge of the gum tissue. When a tooth fractures below the gum line or when excess tissue obscures the enamel, the biologic width must be surgically corrected. Unlike a simple gingivectomy, which only trims soft tissue and often results in regrowth within weeks, a true crown lengthening procedure reshapes both the bone and the overlying gum. This dual approach produces a stable, permanent repositioning of the gum line because the body no longer needs to rebuild tissue to satisfy the biologic width.
At The Loft Dental Studio, Dr. Chanook David Ahn performs crown lengthening using microsurgical instruments, digital imaging, and platelet-rich fibrin therapy to maximize precision and minimize recovery time. Newport Beach patients benefit from a specialist who has performed thousands of periodontal surgeries and understands the fine details that separate a good surgical outcome from a great one.
Selecting the right provider for crown lengthening surgery is one of the most important decisions you can make for the long-term health and appearance of your smile. While general dentists and some cosmetic practices in Newport Beach may offer gum reshaping procedures, there is a meaningful difference between a basic gingivectomy and a comprehensive crown lengthening performed by a board-certified periodontist.
A board-certified periodontist has completed a minimum of 3 additional years of surgical residency training beyond dental school, focused entirely on the hard and soft tissues that surround and support teeth. This training includes advanced flap surgery, bone recontouring, microsurgical technique, and a deep understanding of tissue healing biology. To earn board certification from the American Board of Periodontology, a periodontist must also pass rigorous written and oral examinations that test both clinical knowledge and surgical judgment.
The Specialist Advantage: Studies in the Journal of Periodontology consistently demonstrate that crown lengthening performed by a periodontist with proper bone recontouring has significantly lower rates of tissue relapse compared to soft-tissue-only procedures. When biologic width is correctly established, the gum line stays where the surgeon places it.
Functional crown lengthening is the procedure of choice when a tooth has fractured, decayed, or worn down to a point where there is not enough tooth structure visible above the gum for a dentist to properly seat a crown, bridge, or large filling. Without adequate exposed tooth structure, a restoration cannot achieve a proper marginal seal. An unsealed margin allows bacteria and saliva to leak beneath the crown, causing recurrent decay, infection, and eventual loss of both the restoration and the tooth.
By exposing adequate tooth structure through controlled bone and tissue reshaping, functional crown lengthening can save a tooth that might otherwise need to be extracted and replaced with a dental implant. This is frequently the more conservative and cost-effective treatment path, preserving the natural tooth root and the bone that surrounds it.
Many Newport Beach patients seek cosmetic crown lengthening because they feel their smile shows too much gum tissue and not enough tooth. A gummy smile can make perfectly healthy teeth appear short, uneven, or childlike. In many cases, the teeth beneath the gum tissue are actually normal-sized or even large, but excess tissue conceals them.
The most common cause of a gummy smile is a condition called altered passive eruption. During normal tooth development, the gum tissue is supposed to recede to its final adult position as the teeth fully erupt into the mouth. In patients with altered passive eruption, this process does not complete, and the tissue remains covering a significant portion of the enamel. The result is teeth that appear short and a smile that shows a disproportionate amount of gum.
Dr. Ahn evaluates the full aesthetic picture before any cosmetic crown lengthening procedure. This includes measuring the amount of visible tooth, the amount of gum display when smiling, the position of the underlying bone, the lip line dynamics, and the symmetry between teeth. The goal is to design a new gum line that follows the natural proportions of an ideal smile: central incisors and canines slightly longer than the lateral incisors, with gum margins that follow a gentle, flowing curve from tooth to tooth.
Cosmetic crown lengthening typically addresses the 6 to 10 teeth in the smile zone. The procedure involves raising a gum flap, recontouring the underlying bone to a planned level, and then repositioning the tissue to reveal the full natural tooth. Because both bone and tissue are addressed, the result is permanent. Patients see the initial improvement immediately after surgery, with the final refined result appearing over the following 3 to 4 months as the tissue matures.

Understanding what happens during your crown lengthening appointment helps eliminate anxiety and allows you to prepare properly. Here is a detailed walkthrough of the process at our Costa Mesa office.
Every case begins with a thorough clinical evaluation. Dr. Ahn examines the affected teeth, takes digital radiographs or a cone-beam CT scan when indicated, and measures the existing tooth height, tissue thickness, and bone levels. For functional cases, he reviews the restoration plan with your general dentist to understand exactly how much additional tooth structure is needed. For cosmetic cases, he evaluates your smile from multiple angles, assesses lip dynamics, and designs a new gum architecture that will look natural and proportional.
Crown lengthening is performed under local anesthesia to ensure complete comfort throughout the procedure. For patients who experience dental anxiety, The Loft Dental Studio also offers IV sedation, oral sedation, and nitrous oxide. Many Newport Beach patients appreciate having sedation available, as it allows them to feel completely relaxed during the surgery. Learn more about sedation options.
Dr. Ahn creates precise incisions in the gum tissue and elevates a mucoperiosteal flap to expose the underlying bone. Using microsurgical instruments, he reshapes the alveolar bone to the predetermined level, removing just enough to establish proper biologic width, typically about 3 millimeters between the new bone crest and the planned gum margin. For cosmetic procedures spanning multiple teeth, the bone recontouring is carefully calibrated to create perfect symmetry across the smile zone. The gum flap is then repositioned at its new, lower level and sutured into place.
Dr. Ahn incorporates platelet-rich fibrin therapy into every crown lengthening procedure. PRF is prepared from a small sample of the patient's own blood, spun in a centrifuge to concentrate growth factors, and placed at the surgical site. This accelerates soft tissue healing, reduces post-operative inflammation, and improves overall comfort during recovery.
Newport Beach residents are just 10 minutes from expert periodontal care. Dr. Ahn provides thorough evaluations and personalized treatment plans for both functional and cosmetic crown lengthening.
Call (714) 549-7030Crown lengthening recovery is generally straightforward. Most Newport Beach patients describe the healing process as more comfortable than they anticipated, especially with the PRF therapy and microsurgical approach used by Dr. Ahn.
The cost of crown lengthening depends on the type of procedure, the number of teeth involved, and the complexity of bone recontouring required. The Loft Dental Studio provides detailed cost estimates after your evaluation so there are no surprises.
Functional crown lengthening is often partially covered by PPO dental insurance because it is classified as a medically necessary procedure. Coverage typically falls between 50 and 80 percent depending on your plan. Cosmetic procedures are generally not covered. We accept most major PPO plans including Delta Dental, Cigna, MetLife, Guardian, Aetna, United Healthcare, and Blue Cross Blue Shield. Financing is available through CareCredit, and we accept FSA and HSA funds. For more details, visit our Insurance & Payment page.

Crown lengthening is a specialized periodontal surgery that involves both bone recontouring and soft tissue reshaping. While many general dentists in Newport Beach may offer a basic gingivectomy, which only trims soft tissue, true crown lengthening requires the expertise of a board-certified periodontist who has completed 3 additional years of surgical residency after dental school. Dr. Chanook David Ahn at The Loft Dental Studio is Yale-trained and has placed over 5,000 implants and performed thousands of periodontal surgeries. The 10-minute drive from Newport Beach gives you access to a level of surgical specialization that produces more predictable, longer-lasting results.
Functional crown lengthening is medically necessary when a tooth has broken, decayed, or worn down below the gum line, leaving insufficient tooth structure for your dentist to place a crown or restoration. The procedure exposes more tooth so the restoration can achieve a proper seal. Cosmetic crown lengthening, also called gummy smile correction, is performed when excess gum tissue covers too much of your teeth, making them appear short or creating an asymmetric gum line. The goal is to reveal more of the natural tooth and create a balanced, proportional smile. Both procedures involve bone recontouring and soft tissue reshaping, and both are performed by Dr. Ahn using microsurgical techniques.
After crown lengthening surgery, you should avoid strenuous physical activity for the first 3 to 5 days to minimize swelling and reduce the risk of bleeding. Light walking along the beach is generally fine after the first 48 hours, but you should avoid swimming in the ocean or pool for at least 7 to 10 days until sutures are removed, because salt water, chlorine, and bacteria can irritate the surgical site. Sun exposure can also increase swelling, so wearing a hat and staying hydrated is important if you are outdoors during the first week. By the second week after surgery, most patients can resume normal beach activities.
Functional crown lengthening is frequently covered by PPO dental insurance plans because it is classified as a medically necessary procedure that enables a tooth to be restored. Coverage typically ranges from 50 to 80 percent of the allowed fee depending on your plan. Cosmetic crown lengthening for gummy smile correction is generally considered elective and is not covered. The Loft Dental Studio accepts most major PPO plans including Delta Dental, Cigna, MetLife, Guardian, Aetna, United Healthcare, and Blue Cross Blue Shield. We also offer financing through CareCredit with low-interest and interest-free options, and we accept both FSA and HSA funds. Our team verifies your benefits before treatment so you know your exact out-of-pocket cost.
A referral is not required to schedule a crown lengthening consultation with Dr. Ahn. You are welcome to call our office directly at (714) 549-7030 to book an evaluation. However, many Newport Beach general dentists do refer their patients to Dr. Ahn specifically for crown lengthening because the procedure requires specialized periodontal surgical training. If your dentist has recommended crown lengthening as part of a larger treatment plan, such as a crown or bridge, Dr. Ahn will coordinate directly with your referring dentist to ensure the surgical result aligns with the planned restoration. We work with dental offices throughout Newport Beach and the surrounding communities.
