Board-certified specialist in periodontal disease prevention, diagnosis, treatment, and dental implant surgery. Provider of LANAP, PRF, and Exosome therapies. Certified Wilckodontics (PAOO/SFOT) provider since 2016.
Dr. Ahn's core belief: "SAVE teeth and MAINTAIN."
Dr. Chanook David Ahn is a Yale-trained, board-certified periodontist who has placed more than 5,000 dental implants and saved thousands more teeth that other dentists recommended for extraction. Every tooth is given a chance unless the clinical situation shows a 100% failure rate. When implants are needed, Dr. Ahn plans each case so the restoration, implant, bone, and tissue work in harmony — optimizing esthetics and function simultaneously. Each implant is digitally simulated before surgery and placed using 3D-printed guides. As he puts it: "Surgery is the easy part. The planning is what determines your outcome."
Nothing is better than natural teeth. Dr. Ahn specializes in advanced periodontal therapies and regenerative techniques designed to preserve and restore your natural dentition. Dental implant surgery is performed only when absolutely necessary, after exhausting all tooth-saving options.
This philosophy, grounded in decades of clinical experience and cutting-edge research, drives every treatment decision. Dr. Ahn combines the latest periodontal technologies—including LANAP laser therapy, PRF (Platelet-Rich Fibrin), and regenerative exosome treatments—with meticulous surgical technique to achieve optimal aesthetic and functional outcomes.
Dr. Ahn's clinical philosophy is built on a single conviction: nothing is better than a natural tooth. In a specialty where implant placement generates significantly more revenue than tooth preservation, this is not a neutral position. It is a deliberate choice to prioritize the patient's long-term interest over the simpler, more profitable path.
Every tooth that arrives in Dr. Ahn's operatory gets a chance. He will not recommend extraction unless the clinical evidence — radiographic bone levels, probing depths, mobility patterns, furcation involvement, and the patient's systemic health — demonstrates a situation where the prognosis is truly hopeless. A tooth with a 30% chance of survival still has a 30% chance. A tooth with advanced bone loss that can be stabilized with regenerative surgery and disciplined maintenance deserves that attempt before anyone reaches for the forceps. The only teeth Dr. Ahn recommends extracting are those where the clinical situation shows a 100% failure rate — where biology has made the outcome certain, and preserving the tooth would compromise the health of the surrounding teeth and bone.
This save-first philosophy does not mean implants are avoided when they are genuinely needed. When a tooth cannot be saved, or when a patient presents with an edentulous space, Dr. Ahn approaches implant placement with the same meticulous planning he applies to every procedure. Every implant case is digitally planned using CBCT 3D imaging and surgical simulation software before any incision is made. The implant position, angulation, depth, and relationship to adjacent teeth and vital structures are determined virtually, then translated to the surgical site using 3D-printed surgical guides. This process eliminates guesswork and dramatically reduces the risk of complications.
As Dr. Ahn puts it: "Surgery is the easy part. The planning is what determines your outcome." The hours spent analyzing a 3D scan, simulating different implant positions, evaluating bone density at each potential site, and coordinating with the prosthodontist on the final restoration design — that is where the outcome is decided. The surgery itself is the execution of a plan that was already optimized before the patient sat down in the chair. This planning-first approach is why Dr. Ahn's implant cases have a success rate that consistently exceeds published national averages, even in complex cases involving bone grafting, sinus augmentation, or immediate placement protocols.

Each stage of Dr. Ahn's education built on the last. Dental school at Tufts provided the clinical foundation — the diagnosis, treatment planning, and hands-on patient care that every dentist needs. The General Practice Residency at Yale-New Haven Hospital was a landmark program — Dr. Ahn was the inaugural resident of Yale's first-ever two-year GPR, designed to provide depth in both surgical and prosthodontic disciplines that a standard one-year GPR cannot match. He earned recognition as Chief Resident and Resident of the Year. The periodontics specialty residency then provided three concentrated years of advanced surgical training: dental implant placement, bone regeneration, gum surgery, laser therapy, and the management of medically complex patients.
After residency, Dr. Ahn became the sole associate of Dr. Joan Otomo-Corgel — former President of the American Academy of Periodontology and recipient of the AAP's Gold Medal Award, the highest honor in the specialty. For six years, Dr. Ahn worked alongside Dr. Otomo-Corgel in her private practice, absorbing four decades of clinical wisdom until her retirement. This mentorship shaped the standard of care Dr. Ahn brings to every patient at The Loft Dental Studio: meticulous treatment planning, conservative-first philosophy, and the expectation that every case should be treated as if it were your own family member.
His ongoing appointment as Clinical Faculty at UCLA School of Dentistry ensures that he stays current with the latest research and techniques by teaching implant surgery and periodontics to dental students and residents.
Dr. Ahn is certified by the American Board of Periodontology (ABP), the only recognized certifying board for the specialty of periodontics in the United States. Board certification is a voluntary credential — it is not required to practice as a periodontist, which means that earning it represents a deliberate commitment to the highest standard of clinical knowledge and judgment.
The certification process requires passing comprehensive written and oral examinations that test both theoretical knowledge and the ability to apply that knowledge to complex clinical scenarios. Fewer than half of practicing periodontists in the United States hold board certification. For patients, choosing a board-certified periodontist provides an additional level of assurance that their specialist has voluntarily submitted to the most rigorous peer evaluation available in the field and has demonstrated mastery across all areas of periodontal medicine and surgery.
Dr. Ahn's clinical practice spans the full spectrum of periodontal and implant surgery. His areas of expertise include LANAP laser therapy, dental implant placement and restoration (single tooth through full-arch), Wilckodontics (PAOO/SFOT — accelerated orthodontics, certified since 2016), bone regeneration and guided tissue regeneration, gum grafting for recession, crown lengthening for gummy smile correction and restorative access, and the treatment of aggressive and refractory periodontitis. He uses CBCT 3D imaging, digital periodontal charting, and PRF therapy as standard components of care.
