Should You Save Your Tooth or Get a Dental Implant? A Periodontist Who Does Both Explains

This is the most important question in modern dentistry. And it is the question I answer more than any other in my practice: should you try to save your natural tooth, or should you have it extracted and replaced with a dental implant?

I am uniquely positioned to give you an honest answer. As a board-certified periodontist, I am the specialist trained to save teeth. Periodontists complete three additional years of residency training beyond dental school focused specifically on the supporting structures of teeth — the gums, bone, and periodontal ligament. We are the last line of defense before extraction. But I am also the specialist who places dental implants. I have placed over 5,000 implants in my career. I know what implants can do, and I know their limitations.

This means I have zero financial incentive to push you toward either option. Whether I save your tooth or place an implant, I am the one performing the procedure. My only incentive is to give you the outcome that will serve you best for the rest of your life. And in the vast majority of cases, that means saving your natural tooth.

Why Saving a Tooth Is Almost Always the First Choice

Your natural tooth is a biological marvel that no dental restoration has ever been able to fully replicate. To understand why saving a tooth is almost always preferable, you need to understand what makes a natural tooth irreplaceable.

The Periodontal Ligament: What an Implant Can Never Have

Every natural tooth is suspended in bone by a thin layer of tissue called the periodontal ligament (PDL). This structure is only about 0.2 millimeters wide, but it performs functions that are profoundly important to your oral health:

• Proprioception: The PDL contains nerve endings that give you the ability to feel pressure when you bite down. You can detect something as thin as a human hair between your teeth. This sensory feedback protects you from biting too hard, helps you chew food efficiently, and allows you to detect problems early. A dental implant is fused directly to bone (osseointegration) and has no PDL — which means it has no feeling. Implant patients cannot detect biting forces with the same precision, which increases the risk of overloading the implant or fracturing the restoration.
• Natural bone stimulation: The PDL acts as a shock absorber and transmits chewing forces to the surrounding bone in a way that stimulates healthy bone metabolism. This natural, distributed force keeps the bone around the tooth vital and healthy. An implant transmits force directly to bone without the cushioning effect of the PDL, which creates a fundamentally different stress pattern.
• Biological adaptability: A natural tooth with an intact PDL can respond to changes in force. It can undergo minor orthodontic movements. It can heal from minor trauma. An implant is rigid — once it is placed, it does not adapt.

The point is not that implants are bad. Implants are an extraordinary technology, and I have dedicated a significant portion of my career to placing them with precision. The point is that a natural tooth, even one that has been heavily treated, retains biological advantages that no engineered replacement can match.

How a Periodontist Can Save Teeth Others Cannot

Many patients come to my office after being told by their general dentist that a tooth needs to be extracted. In a significant number of these cases, the tooth can be saved — but it requires specialized techniques that go beyond general dental training. This is not a criticism of general dentists. It is simply a reflection of the fact that periodontists spend three additional years training in exactly these procedures.

I spent six years as the sole associate of Dr. Joan Otomo-Corgel, a former president of the American Academy of Periodontology. That experience shaped my approach to every clinical decision. Before that, I completed my General Practice Residency at Yale-New Haven Hospital (inaugural class, Chief Resident, Resident of the Year) and my periodontics specialty residency at the VA Greater Los Angeles Healthcare System, UCLA-affiliated (Chief Resident). The depth of training matters because the techniques that save teeth require precision, judgment, and experience.

Advanced Tooth-Saving Techniques

• LANAP laser therapy: The Laser-Assisted New Attachment Procedure uses a specific wavelength of laser energy to selectively remove diseased tissue while preserving healthy tissue. LANAP is the only laser protocol with peer-reviewed evidence of true periodontal regeneration — new bone, new cementum, and new periodontal ligament attachment. For teeth compromised by periodontal disease, LANAP can often turn a questionable prognosis into a favorable one.
• Bone regeneration and grafting: When bone has been lost around a tooth due to infection or disease, bone grafting materials and growth factors can be used to rebuild what was lost. Guided tissue regeneration (GTR) uses barrier membranes to direct the growth of new bone and attachment tissue into defects that would otherwise not heal on their own.
• Root amputation: For multi-rooted teeth (molars), it is sometimes possible to remove one diseased root while preserving the others. This allows the tooth to continue functioning rather than being extracted entirely.
• Hemisection: Similar to root amputation, hemisection involves splitting a multi-rooted tooth in half and retaining the healthy portion. The preserved half can then be restored with a crown and continue to serve the patient for years or decades.
• Guided tissue regeneration (GTR): This technique uses biocompatible membranes placed over bone defects to prevent fast-growing soft tissue from filling in spaces where bone needs to regenerate. The membrane creates a protected space where bone-forming cells can do their work without competition from gum tissue cells.

These are not experimental procedures. They are well-documented, evidence-based techniques that periodontists are specifically trained to perform. The difference between a tooth being "hopeless" and a tooth being savable often comes down to whether these options were considered.

When Extraction and an Implant Is the Right Decision

My save-first philosophy does not mean I save every tooth at all costs. That would be irresponsible. There are clinical situations where the evidence clearly shows that the tooth cannot be predictably saved, and attempting to do so would waste the patient's time, money, and biological resources — particularly bone, which is better preserved for implant placement than lost to a failing tooth.

Extraction becomes the right decision when:

• Vertical root fracture: A crack that runs vertically along the root of the tooth, extending below the bone level. Unlike horizontal fractures or craze lines, vertical root fractures cannot heal and will inevitably lead to infection and progressive bone loss. The sooner the tooth is removed, the more bone is preserved for implant placement.
• Severe internal resorption: A process where the tooth's own cells begin to destroy the root from the inside. When internal resorption is advanced, the root structure becomes so compromised that the tooth cannot be predictably retained.
• Extensive decay below bone level: When tooth decay extends significantly below the level of the bone and cannot be accessed through crown lengthening or other surgical approaches, the tooth may not be restorable.
• Hopeless periodontal prognosis: When bone loss around a tooth is so severe — circumferential, extending to the apex, with grade III mobility — that no regenerative procedure can restore adequate support.
• Non-restorable tooth structure: When so much of the clinical crown is lost to decay, fracture, or previous restoration that no crown or onlay can be reliably retained, even after surgical crown lengthening.

In these situations, I recommend extraction and implant placement with the same conviction I bring to saving teeth. And because I have placed over 5,000 implants, patients can trust that the implant will be placed with the same level of precision and care that defines every procedure at The Loft Dental Studio.

Natural Tooth vs Dental Implant: A Direct Comparison

The Financial Reality

Beyond the biological arguments, there is a straightforward financial case for saving your natural tooth whenever possible.

Saving a tooth — typically involving root canal therapy and a crown — generally costs between $2,500 and $4,000. The treatment is usually completed in two to three visits over a few weeks, and you retain your natural tooth.

Extracting and replacing a tooth with an implant involves multiple procedures: the extraction itself, possible bone grafting to preserve or rebuild the socket, a healing period of three to six months, implant placement surgery, another healing period of three to six months for osseointegration, placement of the abutment, and fabrication and delivery of the final crown. The total cost typically ranges from $4,500 to $7,000 or more, and the entire process can take six to twelve months from start to finish.

Dental insurance often covers a larger percentage of tooth-saving procedures (root canals, crowns, periodontal treatments) than it does for implants, which many plans still classify as a major or excluded benefit. This means the out-of-pocket difference can be even greater than the raw numbers suggest.

There is no scenario where extracting a savable tooth and placing an implant makes financial sense. The only time an implant is the cost-effective choice is when the tooth genuinely cannot be saved — because attempting to save a tooth that is destined to fail wastes the cost of the failed treatment and may compromise the bone available for the eventual implant.

Dr. Ahn's Save-First Decision Framework

Every patient who comes to The Loft Dental Studio with a questionable tooth goes through the same rigorous evaluation process. This is not a casual opinion — it is a systematic, evidence-based framework designed to give every tooth its best chance.

Step 1: Comprehensive Periodontal Evaluation with CBCT

The foundation of every decision is accurate diagnosis. I use CBCT (cone beam computed tomography) 3D imaging to visualize the tooth, its roots, the surrounding bone, and any pathology in three dimensions. Traditional 2D X-rays can miss root fractures, underestimate bone loss, and fail to show the true extent of lesions. CBCT eliminates the guesswork.

Step 2: Evaluate All Tooth-Saving Options

Before any discussion of extraction, I systematically evaluate every possible approach to saving the tooth. Can LANAP therapy address the periodontal component? Is bone regeneration feasible given the defect morphology? Would root amputation or hemisection preserve a functional tooth? Is retreatment of a failed root canal or an apicoectomy a viable option? Only after each of these options has been considered — and the patient understands why each one will or will not work for their specific situation — do we move to the next step.

Step 3: Only If the Tooth Is Truly Hopeless, Plan the Implant

If the clinical evidence shows that no tooth-saving approach offers a predictable long-term outcome — if the tooth has a near-100% failure rate regardless of intervention — then and only then do I recommend extraction and implant placement. I explain exactly why the tooth cannot be saved, what would happen if we attempted to save it, and what the implant treatment plan looks like.

Step 4: If an Implant Is Needed, Place It with Precision

When an implant is the right answer, patients benefit from the fact that the same clinician who exhaustively evaluated their tooth is also the one placing their implant. With over 5,000 implants placed, I bring the same precision, the same technology, and the same uncompromising standards to implant placement that I bring to every periodontal procedure.

Common Scenarios Where Patients Are Told to Extract — But Teeth Can Often Be Saved

These are the situations I see most frequently in my practice — patients who were told a tooth needs to come out, but where the clinical reality is more nuanced than the initial recommendation suggested.

"Your bone level is too low"

This is one of the most common reasons patients are told extraction is their only option. And while severe bone loss can indeed render a tooth hopeless, many cases of significant bone loss can be addressed through bone regeneration procedures. The morphology of the bone defect matters enormously: vertical (infrabony) defects surrounded by bony walls are often excellent candidates for guided tissue regeneration. Before accepting that "the bone is too low," a periodontist should evaluate the specific defect architecture using 3D imaging.

"Your gum disease is too advanced"

Advanced periodontal disease is the leading cause of tooth loss in adults — but "advanced" does not automatically mean "hopeless." LANAP laser therapy combined with bone regeneration has allowed me to save thousands of teeth that were classified as having a poor or questionable prognosis. The key is treating the disease aggressively and comprehensively, not just accepting that the tooth will eventually fall out.

"Your tooth is cracked"

Not all cracks are created equal. A craze line (a superficial crack in the enamel) is clinically insignificant. A cracked tooth where the crack extends into the dentin but not below the bone can often be saved with a crown. Even some deeper cracks may be manageable depending on the direction and extent. The only type of crack that consistently indicates extraction is a true vertical root fracture that extends below the bone level. CBCT imaging and careful clinical examination can distinguish between these scenarios.

"Your root canal failed"

A failed root canal does not automatically mean the tooth needs to be extracted. Endodontic retreatment — where the original root canal is redone with modern techniques and materials — has a high success rate. In cases where retreatment is not feasible or has already failed, an apicoectomy (a surgical procedure where the tip of the root is removed and sealed) can often save the tooth. Extraction should be considered only after these options have been explored.

Why a Second Opinion Matters

I want to be direct about this: you should always get a second opinion before extracting a tooth. Not because your dentist is wrong — general dentists are outstanding clinicians who manage the vast majority of dental problems with great skill. But because extraction is irreversible. Once a tooth is removed, it can never be put back. And the consequences of that decision — the need for an implant or bridge, the bone remodeling that follows extraction, the loss of the periodontal ligament — will affect you for the rest of your life.

A second opinion from a board-certified periodontist specifically is valuable because periodontists have the deepest training in the procedures that save teeth: bone regeneration, guided tissue regeneration, laser therapy, root surgery, and comprehensive periodontal management. We see options that other specialists may not have been trained to provide.

At The Loft Dental Studio, second opinion consultations include a thorough clinical examination, 3D CBCT imaging when indicated, and an honest assessment of every option available. If the tooth can be saved, I will explain how. If it truly cannot, I will explain why — and present a clear plan for the best possible implant outcome.

The Bottom Line

This is my core philosophy, and it shapes every decision I make as a clinician: no tooth is given up on unless the clinical situation shows a near-certain chance of failure regardless of treatment. Every tooth deserves a thorough evaluation. Every patient deserves to know all of their options. And every extraction should be a last resort, not a first instinct.

If you are facing a decision about whether to save a tooth or get an implant, I encourage you to seek the opinion of a specialist who does both. Not a specialist who only saves teeth and has no implant experience. Not a clinician who primarily places implants and may be less familiar with advanced tooth-saving techniques. But someone who has dedicated their career to both — and who will tell you the truth about which option gives you the best long-term outcome.

That is what we do at The Loft Dental Studio. Every day. One tooth at a time.
