Santa Ana residents are just 10 minutes from expert crown lengthening by board-certified periodontist Dr. Chanook David Ahn. From rescuing broken teeth to transforming gummy smiles, our precision bone and tissue recontouring delivers results that last. Take Bristol St south or the 55 Freeway to reach our Costa Mesa office.
Crown lengthening is a targeted periodontal surgery designed to reveal more of a tooth's natural structure by carefully removing gum tissue and recontouring the bone that surrounds it. For Santa Ana patients dealing with a broken tooth that sits below the gum line or a smile that shows too much gum, this procedure addresses the root cause rather than masking the problem. The surgery serves two fundamentally different purposes depending on the clinical situation: functional crown lengthening creates the access a restorative dentist needs to rebuild a compromised tooth, while cosmetic crown lengthening reshapes the visible gum architecture to correct a disproportionate or gummy smile.
At the heart of every successful crown lengthening is a biological principle that periodontists call the biologic width. This refers to the approximately 2 to 3 millimeters of space that the body naturally maintains between the top of the alveolar bone and the free margin of the gum tissue. Within this zone, connective tissue fibers and a specialized cell layer called the junctional epithelium create a seal that protects the bone from bacterial invasion. When a crown margin, a fracture line, or decay intrudes into this space, the body reacts with persistent inflammation, progressive bone resorption, and unpredictable gum recession as it fights to recreate that protective buffer. Understanding and respecting the biologic width is what separates a lasting crown lengthening result from a procedure that fails within months.
Because the biologic width involves both bone and soft tissue, effective crown lengthening must address both structures. Removing gum tissue alone, a simpler procedure called gingivectomy, may create the appearance of improvement initially. However, without repositioning the bone, the body will regenerate the soft tissue to its original position as it re-establishes the biologic width. This is precisely why crown lengthening should be performed by a board-certified periodontist who has specialized training in osseous (bone) surgery and tissue healing biology.
When a tooth suffers structural damage that extends beneath the gum line, the remaining visible portion may be too short for a dentist to anchor a crown, onlay, or other restoration securely. Without adequate tooth structure rising above the gum margin, any restoration placed will lack retention, fail to seal properly against bacteria, and ultimately come loose or develop recurrent decay underneath. Functional crown lengthening solves this problem by surgically exposing more of the intact tooth, giving the restorative dentist the foundation needed for a durable, well-sealed repair.
Before You Agree to Extraction: Many teeth that are recommended for removal can actually be preserved through crown lengthening and a well-planned restoration. If the root is intact, free of vertical fractures, and surrounded by adequate bone, crown lengthening gives the tooth a second chance. Preserving your natural tooth avoids the greater complexity and cost of an implant or bridge. Dr. Ahn carefully assesses each case with digital imaging to determine whether crown lengthening is a viable and predictable option before any treatment begins.
A gummy smile is one of the most common aesthetic concerns patients bring to a periodontist. When three or more millimeters of gum tissue are visible above the upper teeth during a full smile, the teeth can appear short, square, or uneven, even when the teeth themselves are perfectly healthy and normal in size. Cosmetic crown lengthening removes the excess tissue and sculpts the underlying bone to reveal the full, natural tooth hidden beneath, producing a dramatic improvement in smile proportions.
Dr. Ahn plans every cosmetic crown lengthening case by evaluating the smile zone, typically the six to ten upper front teeth visible during smiling. He measures each tooth's width-to-length ratio, assesses the symmetry between matching teeth on either side of the midline, and designs a gum architecture where the canine and central incisor margins sit slightly higher than the lateral incisors, following the natural curvature of a balanced smile. This meticulous planning produces results that look naturally beautiful rather than surgically altered.

The distinction between having crown lengthening performed by a board-certified periodontist versus another provider is not a matter of preference but of training depth and surgical capability. Crown lengthening is an osseous surgery, meaning it involves reshaping bone. A board-certified periodontist like Dr. Ahn has completed three additional years of full-time surgical residency after dental school, focused exclusively on the hard and soft tissues that support and surround teeth. This residency training includes hundreds of bone recontouring procedures, flap surgeries, and tissue grafts, building a level of experience that cannot be replicated through weekend courses.
The single most important factor in a successful crown lengthening outcome is whether the bone is properly reshaped. When I plan a crown lengthening, I am not thinking about how much tissue to remove. I am calculating exactly where the bone needs to be so that the tissue will heal to a specific, predictable position. Bone dictates tissue position. If the bone is left untouched and only soft tissue is trimmed, biology will override the surgery every time, and the tissue will return to where it started. This is why crown lengthening belongs in the hands of a surgeon who reshapes bone routinely and understands the healing biology that follows. Every case I treat at The Loft Dental Studio is planned backward from the final goal, whether that is a restoration margin or an ideal gum line, to the precise bone architecture needed to achieve it.
Knowing what happens during your appointment removes uncertainty and helps you prepare. Here is how Dr. Ahn approaches every crown lengthening case for Santa Ana area patients.
Your initial visit includes a focused examination of the teeth in question, digital radiographs to assess bone levels, and clinical measurements of the existing tissue and tooth structure. For functional cases, Dr. Ahn reviews your referring dentist's treatment plan and discusses the restorative requirements to ensure the crown lengthening provides the access your dentist needs. For cosmetic cases, he photographs your smile from multiple angles, evaluates lip dynamics, measures tooth dimensions, and maps the ideal gum architecture. This planning phase ensures the surgical result integrates seamlessly with your overall treatment goals.
Crown lengthening is performed under local anesthesia to ensure complete numbness throughout the procedure. For patients who experience dental anxiety or prefer a more relaxed experience, IV sedation, oral sedation, and nitrous oxide are available. Learn more about our sedation options.
Dr. Ahn begins by making precise incisions in the gum tissue surrounding the tooth or teeth being treated. The tissue is elevated as a flap, exposing the underlying alveolar bone. Using microsurgical instruments under magnification, he reshapes the bone to the planned level, removing just enough to establish the proper biologic width, typically positioning the bone crest approximately 3 millimeters below where the final gum margin will rest. For cosmetic cases involving multiple teeth, the bone recontouring is performed symmetrically across the entire smile zone to ensure even, natural-looking gum margins.
Once the bone has been sculpted to the correct contour, the gum tissue flap is draped back into position at its new, lower level and secured with fine sutures. Dr. Ahn carefully shapes the tissue margins to create smooth, flowing contours that will mature into a natural-looking gum line. For functional cases, the previously hidden tooth structure is now fully exposed and accessible for your restorative dentist.
Dr. Ahn applies PRF (Platelet-Rich Fibrin) membranes derived from your own blood to the surgical site. PRF concentrates growth factors and healing cells at the wound, accelerating soft tissue repair, reducing post-surgical swelling, and improving overall comfort during recovery. This biological enhancement is included at no additional cost with every crown lengthening procedure.
Whether you need more tooth structure exposed for a restoration or want to transform a gummy smile, Dr. Ahn provides expert evaluation and personalized treatment planning for Santa Ana area patients.

Recovery from crown lengthening follows a predictable course. Here is what Santa Ana area patients can expect during the healing process.
The Loft Dental Studio is conveniently located in the South Coast Metro area of Costa Mesa, approximately 10 minutes from central Santa Ana. Our office at 3151 Airway Ave, Suite F-103 is easily accessible via several routes.
Head south on Bristol Street from downtown Santa Ana. Continue straight through the South Coast Plaza area. Turn right onto Airway Avenue. Our office is located in the professional complex at Suite F-103 on the left. This route typically takes about 10 minutes depending on traffic.
Take the CA-55 (Costa Mesa Freeway) south from Santa Ana. Exit at Baker Street and head west. Turn left onto Airway Avenue. The office will be on your right. This route is approximately 10 minutes and is often faster during peak hours when Bristol Street experiences heavier surface traffic.
In many cases, yes. When a tooth has fractured or decayed below the gum line, some providers recommend extraction because they cannot access enough tooth structure to place a restoration. However, if the remaining root is structurally sound, has adequate length, and is supported by healthy bone, crown lengthening can expose the hidden tooth structure and make it restorable again. Dr. Ahn evaluates the root integrity, surrounding bone levels, and overall prognosis before recommending crown lengthening as an alternative to extraction. Saving a natural tooth is almost always preferable to replacing it with an implant or bridge, both in terms of long-term function and cost.
Biologic width refers to the natural distance the body maintains between the crest of the alveolar bone and the edge of the gum tissue, typically measuring about 2 to 3 millimeters. This zone consists of connective tissue attachment and junctional epithelium that forms a biological seal around the tooth. When a restoration margin encroaches on this zone, the body responds with chronic inflammation, bone loss, and gum recession as it attempts to re-establish the biologic width on its own. Crown lengthening proactively repositions the bone and gum tissue so the biologic width is properly established before the restoration is placed, preventing these complications.
For functional crown lengthening, Dr. Ahn typically treats one to three adjacent teeth in a single appointment. If teeth requiring crown lengthening are in different areas of the mouth, the procedures may be staged across two appointments for patient comfort. For cosmetic crown lengthening to correct a gummy smile, the entire smile zone of six to ten teeth is treated in one session because achieving symmetry requires addressing all visible teeth simultaneously. The procedure for a full cosmetic case generally takes 60 to 90 minutes.
Yes, when performed correctly by a periodontist who reshapes both the bone and soft tissue, crown lengthening produces permanent results. The key to permanence is proper bone recontouring. The body maintains a consistent biologic width between the bone crest and gum margin. Once the bone is reshaped to the desired level, the gum tissue heals and stabilizes at a predictable position relative to the new bone level. This is fundamentally different from a gingivectomy, which only trims soft tissue and often results in tissue regrowth within months because the underlying bone was never modified.
Trimming gum tissue alone, a procedure called gingivectomy, can provide a temporary improvement in appearance or access to tooth structure. However, without reshaping the underlying bone, the biologic width has been violated. Over the following weeks to months, the body responds by regrowing gum tissue to re-establish the natural distance between the bone crest and the tissue margin. This means the results are not permanent and the gummy appearance or insufficient tooth exposure returns. In some cases, repeated soft tissue trimming without bone recontouring can lead to chronic inflammation and unpredictable tissue healing. A proper crown lengthening procedure addresses the bone first, which allows the soft tissue to heal to a stable, permanent position.
If your procedure is performed under local anesthesia alone or with nitrous oxide (laughing gas), you can drive yourself home afterward. Nitrous oxide wears off within minutes of removing the mask, leaving no lingering sedation effects. However, if you choose IV sedation or oral sedation for additional comfort, you will need a responsible adult to drive you home and stay with you for several hours after the procedure. The sedation effects can take four to eight hours to fully wear off. Dr. Ahn's team will discuss your sedation options during the consultation and provide specific instructions for the day of surgery.
