If you have been told your teeth are hopeless and need to be extracted, a periodontal second opinion could change everything. Dr. Chanook David Ahn is a board-certified periodontist who has saved thousands of teeth that other dentists recommended for extraction.
This is not about blaming your general dentist. General dentists are skilled professionals who provide excellent care across a broad scope of services. But general dentistry and periodontics are different specialties with different training, different tools, and different perspectives on the same clinical problem. When your general dentist looks at an X-ray showing severe bone loss around a tooth, they are evaluating that tooth through the lens of what they can offer: extraction and replacement with a dental implant or bridge. That is an honest recommendation based on the tools available to them.
A board-certified periodontist looks at the same X-ray and often sees something different: a tooth that can be saved. Periodontists complete an additional three years of surgical residency training beyond dental school, focused exclusively on the tissues that support teeth — the gums, bone, and periodontal ligament. This training provides access to an entirely different set of treatment options that most general dentists do not perform. LANAP laser treatment can selectively remove diseased tissue and stimulate bone regeneration without scalpels or sutures. Guided bone regeneration with membranes and bone grafting materials can rebuild bone that was considered permanently lost. Tissue engineering with PRF (Platelet-Rich Fibrin) and biologic agents like Emdogain can regenerate the periodontal attachment apparatus. Advanced root planing under surgical magnification can reach areas that standard scaling instruments cannot access.
The difference in perspective is often dramatic. A tooth with a 7-millimeter pocket and 50 percent bone loss might look like a clear extraction case to a general dentist — because in their hands, with their training, it effectively is. That same tooth, evaluated by a periodontist with the training and instrumentation to treat it, may have an excellent prognosis with the right intervention. The problem is not that general dentists are making bad recommendations. The problem is that many patients never get the chance to hear from the specialist who has the tools to offer alternatives.
There is also an economic reality that patients should understand. A single dental implant generates $3,500 to $5,500 in revenue for the practice that places it. Full-arch All-on-4 treatment generates $25,000 to $35,000 per arch. Referring a patient to a periodontist who might save the teeth generates zero revenue. This does not mean dentists are acting in bad faith — the vast majority are making recommendations they genuinely believe are best. But the financial incentive to extract and replace rather than refer and save is a structural reality in dentistry that patients deserve to understand.
The following clinical scenarios represent real cases treated by Dr. Ahn at The Loft Dental Studio. Patient names and identifying details have been omitted to protect privacy, but the clinical details are accurate and representative of the types of cases Dr. Ahn treats regularly.
A patient in their early fifties presented after being told by their general dentist that all of their lower teeth needed to be extracted due to advanced periodontal disease. The treatment plan they had been given called for full lower arch extraction followed by an implant-supported denture. After comprehensive periodontal evaluation including CBCT 3D imaging, Dr. Ahn determined that the majority of the teeth had adequate remaining bone support to attempt salvage. Full-mouth LANAP laser treatment was performed in conjunction with strategic bone grafting at the most severely affected sites. Twenty-six of twenty-eight teeth were saved. At three-plus years of follow-up, all saved teeth remain stable with maintained bone levels and healthy probing depths. The patient avoided a full-arch prosthesis and kept their natural teeth.
A patient was referred to an oral surgeon for extraction of tooth number 19 — a lower first molar — after their dentist identified severe localized bone loss and declared the tooth not saveable. Dr. Ahn's evaluation, including a CBCT scan, revealed that while bone loss was significant on one surface, the remaining surfaces had adequate support. Dr. Ahn performed guided bone regeneration using a resorbable membrane, particulate bone graft, and PRF (Platelet-Rich Fibrin) prepared from the patient's own blood. At re-evaluation, the site had achieved approximately 8 millimeters of vertical bone gain. The tooth was restored with a crown and has remained functional and stable. A tooth that was scheduled for extraction and a $4,500 implant was saved with a procedure that cost a fraction of the replacement.
A patient had been treatment-planned for full-arch All-on-4 on both the upper and lower arches — a combined investment of over $60,000. The patient sought a second opinion. Dr. Ahn's comprehensive evaluation revealed that twenty of the patient's teeth had sufficient bone support and could be saved with strategic periodontal treatment. Full-mouth LANAP was performed, combined with localized bone regeneration at the most compromised sites. Only four teeth ultimately required extraction and were replaced with individual dental implants. The patient saved approximately $45,000 compared to the original full-arch extraction plan and kept twenty natural teeth that their previous dentist had condemned.
Not every tooth can be saved. But the cases above illustrate an important truth: many teeth that are recommended for extraction by general dentists can be saved when evaluated and treated by a board-certified periodontist with the right training, technology, and surgical expertise. The only way to know if your teeth fall into this category is a comprehensive periodontal second opinion.
Honesty is the foundation of the second opinion process. Not every tooth can be saved, and pretending otherwise would be a disservice to patients. There are clinical situations where extraction is genuinely the best option — where attempting to save the tooth would waste time, money, and emotional energy on a losing cause. Dr. Ahn believes in being direct about these situations.
Vertical root fractures are one clear indication for extraction. When a tooth root has cracked vertically, the fracture creates a pathway for bacteria to reach the bone directly, causing rapid and progressive bone destruction that no periodontal treatment can halt. Severe internal resorption — a condition where the body's own cells are dissolving the tooth from the inside — is another situation where extraction is typically the only viable option. Teeth with less than approximately 25 percent of their original bone support remaining have a poor long-term prognosis even with aggressive periodontal treatment, because the remaining attachment is insufficient to withstand normal functional forces. Non-restorable decay that extends significantly below the bone level may make a tooth structurally unsalvageable even if the periodontal support is adequate.
Dr. Ahn's philosophy is straightforward: he would rather tell you a tooth cannot be saved than pretend it can. And he would rather save a tooth that other dentists gave up on than extract it for an implant you did not need. That commitment to honesty in both directions is what makes a periodontal second opinion valuable. You will either learn that your teeth can be saved — or you will gain the confidence that extraction is truly the right path forward.
A periodontal second opinion at The Loft Dental Studio is not a quick glance at your X-rays and a verbal agreement or disagreement with your dentist's plan. It is a comprehensive diagnostic evaluation that examines every aspect of your periodontal health in detail that most general dental offices do not perform.
The evaluation begins with comprehensive periodontal charting — measuring the pocket depth at six points around every tooth in your mouth using a calibrated periodontal probe. This produces a detailed map of attachment levels that reveals exactly where disease is active and how much support each tooth retains. A full-mouth radiographic series provides two-dimensional imaging of bone levels, root anatomy, and pathology. When three-dimensional assessment is needed — which is common in complex cases — a CBCT (cone beam computed tomography) scan provides millimeter-accurate views of bone from every angle, revealing anatomy that standard X-rays cannot show.
Dr. Ahn evaluates tooth mobility using standardized grading scales, assesses furcation involvement in multi-rooted teeth (the degree to which bone loss has extended into the space between roots), and examines root anatomy for factors that affect prognosis such as root length, root proximity, and root form. The clinical examination also includes assessment of the quality and quantity of keratinized tissue, the presence and severity of inflammation, and the identification of local contributing factors such as defective restorations, bite discrepancies, or parafunctional habits.
After the evaluation, Dr. Ahn explains every finding in plain language. He will show you your X-rays and CBCT images, walk you through each tooth's prognosis, and present all available treatment options — including the option to do nothing and monitor. There is no pressure, no sales pitch, and no predetermined treatment plan. The goal is to give you complete information so you can make a fully informed decision about your own teeth.
Beyond the clinical and emotional arguments for saving natural teeth, there is a straightforward financial case that every patient should consider before agreeing to extraction and implant placement.
The numbers speak clearly. Even in a worst-case scenario where periodontal treatment extends a tooth's life by only ten additional years before extraction eventually becomes necessary, the patient has gained a decade of function with their natural tooth at a fraction of the cost of immediate replacement. Ten years of chewing, smiling, and living with the tooth nature gave them — at one-third to one-tenth the cost of the alternative.
Natural teeth also have biological advantages that no implant can replicate. The periodontal ligament — the thin layer of tissue between the tooth root and the bone — provides proprioception, the ability to sense pressure and adjust bite force. This protective mechanism prevents you from biting too hard and damaging the tooth or opposing structures. Dental implants do not have a periodontal ligament and therefore lack this sensory feedback. Natural teeth also distribute forces differently than implants, and multiple adjacent implants create different biomechanical stresses on the jawbone than natural teeth do.
None of this means implants are bad. Dental implants are an extraordinary technology, and Dr. Ahn places them regularly for patients who truly need them. But an implant should be the solution when a tooth genuinely cannot be saved — not the default recommendation when a more conservative option has not been explored.
Same-week appointments are often available. Dr. Ahn will evaluate your teeth, explain every finding, and give you an honest assessment of what can and cannot be saved.

The only way to know for certain is a comprehensive periodontal evaluation by a board-certified periodontist. This includes six-point periodontal charting around every tooth, full-mouth radiographs, and often a CBCT 3D scan to assess bone levels from every angle. Many teeth that appear hopeless on a standard two-dimensional X-ray turn out to have adequate bone support when evaluated in three dimensions. Dr. Ahn has saved thousands of teeth that patients were told needed extraction — including teeth with severe bone loss, deep periodontal pockets, and significant mobility. A periodontal second opinion gives you the information you need to make the right decision about your own teeth.
Any good dentist welcomes second opinions. In medicine, seeking a second opinion before a major procedure is standard practice and widely encouraged — no ethical physician or dentist would discourage it. Your dentist should want you to feel confident in your treatment plan. Most general dentists appreciate when a periodontist confirms their diagnosis, and when a periodontist identifies a tooth-saving alternative, the general dentist benefits too because they retain a patient who keeps their natural teeth rather than leaving the practice after a negative experience. Dr. Ahn works collaboratively with referring dentists and provides detailed reports of his findings and treatment recommendations.
Yes. A comprehensive periodontal evaluation is typically billed under code D0180 (comprehensive periodontal evaluation), which most PPO dental insurance plans cover once per year. This evaluation is a covered diagnostic benefit separate from your routine exam with your general dentist. Additional imaging such as periapical radiographs or CBCT scans, if needed, are billed as separate diagnostic codes that most plans also cover. The Loft Dental Studio accepts Delta Dental, Cigna, MetLife, Guardian, Aetna, United Healthcare, and Blue Cross Blue Shield. The administrative team verifies your specific benefits before your appointment so you understand your coverage and any out-of-pocket costs.
Then you can proceed with your treatment plan with complete confidence, knowing that two independent clinicians — your general dentist and a board-certified periodontist — have evaluated your teeth and reached the same conclusion. This peace of mind is invaluable. Dr. Ahn is honest about prognosis and would rather tell you a tooth cannot be saved than offer false hope. If extractions are truly the best option, Dr. Ahn can place dental implants with the precision and expertise of a board-certified periodontist trained at Yale-New Haven Hospital. Either way, the second opinion ensures you are making a fully informed decision.
In many cases, yes. All-on-4 is an excellent solution when it is truly needed — when the teeth are genuinely beyond saving and a fixed, implant-supported prosthesis is the best path to restoring function and aesthetics. However, All-on-4 is sometimes recommended prematurely, before a periodontist has had the opportunity to evaluate whether strategic treatment could preserve a significant number of natural teeth. Dr. Ahn has treated multiple patients who were scheduled for full-arch All-on-4 and saved fifteen to twenty of their natural teeth using LANAP laser treatment, guided bone regeneration, and targeted periodontal therapy. Natural teeth with healthy periodontal support outperform prosthetic replacements in proprioception, bite force, and long-term maintenance. A periodontal second opinion before full-arch extraction can potentially save you tens of thousands of dollars and preserve irreplaceable natural tooth structure.
