What This Guide Covers and Who It Is For
This guide provides an evidence-based look at the benefits and limitations of LANAP laser gum surgery. It is written for patients who have been diagnosed with periodontal disease and are weighing their surgical options.
LANAP stands for Laser-Assisted New Attachment Procedure. It uses a specific type of laser called the PerioLase MVP-7, which is a free-running, variable-pulsed Nd:YAG (neodymium-doped yttrium-aluminum-garnet) laser operating at a 1064 nm wavelength. The procedure targets diseased tissue inside periodontal pockets (the spaces between gums and teeth that deepen as gum disease progresses) without cutting or stitching the gums. [1] [3]
Gum disease, also called periodontal disease, is a bacterial infection that destroys the bone and tissue supporting your teeth. According to the American Academy of Periodontology, it is one of the most common chronic conditions in adults. [1] Left untreated, it leads to tooth loosening and tooth loss. Surgery becomes necessary when non-surgical treatments like scaling and root planing (a deep cleaning below the gumline) cannot fully control the disease.
Whether LANAP or traditional surgery is better for you depends on the type and severity of your bone loss, your overall health, and your periodontist's clinical judgment. This guide presents both options fairly so you can ask the right questions.
LANAP Pros and Cons: The Core Evidence
LANAP has documented clinical advantages, but it also has clear limitations that patients should understand before choosing it.
Documented Advantages of LANAP
The most notable advantage of LANAP is its FDA clearance (510(k) No. K151763, granted in 2016) for true periodontal regeneration. This means the procedure has demonstrated the ability to stimulate new bone growth, new cementum (the thin layer covering tooth roots), and new periodontal ligament (the fibers connecting teeth to bone). Traditional flap surgery often repairs tissue but does not always achieve true regeneration of all three structures. [3] [4]
This regeneration claim is supported by peer-reviewed human histological studies. In a landmark 2007 study, Yukna et al. performed biopsies on teeth treated with the LANAP protocol and found new cementum and new connective tissue attachment on previously diseased root surfaces. Control teeth that did not receive LANAP healed with long junctional epithelium (essentially scar tissue) rather than true regeneration. [5] A follow-up study by Nevins et al. (2012) confirmed true periodontal regeneration, including new cementum, periodontal ligament, and alveolar bone, at nine months post-operatively. The histological data from this study was submitted to the FDA as part of the evidence supporting the 2016 clearance for the true regeneration claim. [6] [4]
LANAP is a minimally invasive procedure. Because there is no scalpel incision and no sutures, patients typically report less postoperative pain and swelling compared to traditional osseous surgery (surgery where the gum is lifted back and bone is reshaped). The gum tissue is preserved rather than cut away, which typically results in less gum recession after healing. [7] For many patients, this means less tooth sensitivity and a more natural gumline appearance.
The laser's 1064 nm wavelength is highly absorbed by melanin and hemoglobin, which are found in the pigmented, pathogenic bacteria (such as Porphyromonas gingivalis) that drive periodontal disease. Because healthy gum tissue lacks this dark pigmentation, the laser energy passes through it without causing damage. [3] This selective targeting is what allows the procedure to remove diseased tissue while preserving healthy tissue.
Recovery time is generally shorter with LANAP. Many patients return to normal activities within 24 hours, whereas traditional surgery may require several days of modified activity. The laser itself has a bactericidal effect, meaning it kills bacteria on contact, which may reduce the risk of post-surgical infection. [1] [3]
LANAP can be performed with local anesthesia alone, and many patients report that the procedure is more comfortable than they expected. This can be a meaningful advantage for patients who have dental anxiety or who take blood-thinning medications, since there is typically less bleeding involved.
- True regeneration: FDA-cleared (510(k)) to regrow bone, cementum, and periodontal ligament, supported by human histological studies [5] [6]
- Less tissue removal: No scalpel incision, no sutures, less gum recession
- Reduced discomfort: Patients typically report less pain and swelling than with traditional surgery
- Faster recovery: Most patients resume normal activities within a day
- Selective bactericidal effect: The laser targets pigmented bacteria and diseased tissue while leaving healthy tissue largely unaffected
- Less bleeding: May be suitable for patients on blood-thinning medications
Limitations and Drawbacks of LANAP
The biggest limitation of LANAP is the size and maturity of its evidence base. Traditional flap surgery and osseous surgery have decades of long-term clinical trials behind them. LANAP's published research is growing, and peer-reviewed histological studies support its regeneration claims, but the total number of large-scale, randomized controlled trials remains smaller by comparison. Some clinicians and professional organizations consider the evidence promising but still developing. [4]
LANAP is not effective for every type of bone loss pattern. It works best when bone loss occurs in vertical or angular defects (where the bone dips down unevenly along one side of a tooth). Periodontal regeneration requires a stable defect architecture to hold the blood clot and allow bone-forming cells to populate the area. Vertical defects provide bony walls that support this process. [3] In cases of generalized horizontal bone loss (where bone is lost evenly across a wide area), the flat topography provides no lateral support for the clot, making true regeneration highly unpredictable. Traditional surgery with bone grafting may produce better results in these situations. Similarly, furcation defects (bone loss between the roots of multi-rooted teeth) can be difficult to treat with LANAP alone. [7]
The procedure requires a specific, proprietary laser (the PerioLase MVP-7). No other laser has been cleared for the LANAP protocol. This means the procedure is only available from periodontists who have invested in this particular equipment and completed IALD certification. In some areas, access to a certified LANAP provider may be limited.
Insurance coverage can be a challenge. Some dental insurance plans classify LANAP as an alternative or experimental procedure, which may result in reduced or denied reimbursement. Patients should verify their coverage in advance. Even when insurance covers periodontal surgery generally, the LANAP code may be processed differently than traditional surgical codes.
- Smaller evidence base: Fewer large-scale, long-term studies compared to traditional surgery, though peer-reviewed histological evidence supports core claims
- Not ideal for all bone loss patterns: Horizontal bone loss and furcation defects may respond better to traditional approaches
- Proprietary technology: Only available from providers with the PerioLase MVP-7 and IALD certification
- Insurance hurdles: Some plans classify LANAP as experimental, affecting reimbursement
- Limited provider availability: Not every periodontist offers the procedure
LANAP vs. Traditional Flap Surgery: A Fair Comparison
Traditional flap surgery (also called open flap debridement or osseous surgery) involves lifting the gum tissue away from the tooth, cleaning out bacteria and tartar from the root surfaces, reshaping damaged bone, and suturing the gum back into place. It remains the most widely studied and practiced surgical treatment for moderate to severe periodontal disease. [1]
Both approaches aim to reduce pocket depth and stop disease progression. Traditional surgery has strong evidence for pocket reduction and long-term tooth retention. LANAP has peer-reviewed histological evidence supporting regeneration of lost attachment and bone in appropriate defect types. [5] [6] Neither procedure is universally superior. The best choice depends on clinical factors specific to each patient.
One key difference involves tissue management. Traditional osseous surgery often requires apically positioned flaps, which deliberately reposition tissue and expose root surfaces. This produces predictable post-operative gum recession, which can lead to aesthetic compromises and tooth sensitivity. [7] LANAP avoids intentional tissue resection, resulting in significantly less recession in most cases.
Some patients may benefit from a combined approach. A periodontist might recommend LANAP for certain teeth and traditional surgery for others within the same mouth, depending on the pattern of bone loss. This is a clinical decision that requires thorough examination, including current periodontal probing depths and detailed dental X-rays or cone beam CT scans.
What Patients Should Know Before Choosing LANAP
Choosing LANAP requires understanding who benefits most, how to find a qualified provider, and what realistic outcomes look like.
Who Is the Best Candidate for LANAP?
LANAP is typically recommended for adults with moderate to severe chronic periodontitis who have not responded adequately to non-surgical treatment like scaling and root planing. [1] The ideal candidate has vertical bone defects around one or more teeth, meaning the bone loss follows an angular pattern rather than a flat, even pattern.
Patients who take anticoagulant (blood-thinning) medications may be good candidates because LANAP produces less bleeding than traditional surgery. Patients with health conditions that impair healing, such as uncontrolled diabetes, should discuss their specific risks with their periodontist before proceeding with any surgical option. [2]
LANAP is generally performed on adults. There is no strict upper age limit, but overall health status matters more than age alone. Smokers can undergo the procedure, but smoking significantly reduces healing outcomes for any periodontal surgery. Your periodontist will likely encourage smoking cessation before and after treatment.
How to Find a Qualified LANAP Provider
The LANAP protocol is a specific, step-by-step procedure. It is not the same as generic laser gum treatment offered by general dentists using different laser types. Only the PerioLase MVP-7 Nd:YAG laser is FDA-cleared for the LANAP protocol. Providers must complete training through the Institute for Advanced Laser Dentistry (IALD) to perform the full protocol.
When evaluating a provider, ask these questions: Are you a board-certified periodontist? Are you IALD-certified in the LANAP protocol? How many LANAP procedures have you performed? What percentage of your periodontal surgical cases use LANAP vs. traditional surgery? A periodontist who offers both approaches and recommends based on clinical findings, rather than defaulting to one method for every patient, is a good sign.
You can search for periodontists in your area and ask specifically about LANAP certification during your consultation.
Setting Realistic Expectations
LANAP can reduce pocket depths, regenerate bone, and help stabilize loose teeth. However, results vary based on the severity of disease, the type of bone defects present, the patient's overall health, and their commitment to follow-up care. Not every tooth can be saved, even with the best surgical intervention.
Healing after LANAP is a gradual process. Gum tissue may appear clinically healthy and tightly adapted to the tooth within two to four weeks. [3] Bone regeneration is a slower process. Research suggests that evidence of true histological regeneration becomes observable at three to nine months post-operatively. [5] [6] Radiographic (X-ray) evidence of bone fill typically becomes apparent between six and twelve months, as newly formed bone must mineralize sufficiently to become visible on imaging. [8] Your periodontist will schedule follow-up visits to monitor probing depths and radiographic changes over time. Long-term success depends heavily on consistent oral hygiene at home and regular periodontal maintenance visits, typically every three to four months. [1] [2]
What to Expect During and After LANAP
The LANAP procedure follows a defined protocol performed over two visits, each treating one side of the mouth.
Before the Procedure
Your periodontist will perform a thorough periodontal evaluation. This includes measuring pocket depths around every tooth, taking full-mouth X-rays or a cone beam CT scan, and reviewing your medical history. These measurements help determine whether LANAP is appropriate for your specific bone loss pattern.
You will typically be asked to continue taking any regular medications unless your periodontist advises otherwise. Unlike traditional surgery, you usually do not need to stop blood-thinning medications before LANAP. Your periodontist will provide specific pre-procedure instructions based on your health profile.
During the Procedure
The LANAP protocol involves several distinct steps. First, the periodontist uses a thin laser fiber (about the width of three human hairs) to remove diseased tissue lining the periodontal pocket. The laser energy is selectively absorbed by the diseased tissue and bacteria, leaving healthy tissue largely unaffected. [3]
Next, the periodontist uses ultrasonic scalers to remove tartar (calculus) from the root surfaces. The laser is then used a second time at a different setting to create a stable fibrin blood clot at the base of the pocket. This clot is critically important. It acts as a biological seal and physical barrier that holds the gum tissue against the clean tooth root. The clot prevents epithelial downgrowth (where surface cells migrate into the pocket and form scar tissue instead of true regeneration) and creates a protected space where the slower-moving bone cells can regenerate beneath it. [3] [9] No cutting, no stitches.
Each session typically takes one to two hours, depending on how many teeth are being treated. Local anesthesia (numbing injections) is used, and most patients report the procedure is comfortable. The mouth is usually treated in two sessions, one for each side, spaced about one week apart.
Recovery and Aftercare
Most patients experience mild soreness for one to three days after each session. Over-the-counter pain relievers like ibuprofen are typically sufficient. Significant swelling is uncommon. Many patients return to work and normal activities the same day or the following day.
Protecting the blood clot is the most important part of recovery. The fibrin clot created during the procedure is fragile, and dislodging it can compromise the entire regenerative process and leave the pocket vulnerable to bacterial reinfection. For this reason, patients are strictly instructed not to brush or floss the treated surgical areas for 7 to 14 days. [8] [9] During this initial period, plaque control is managed solely through prescribed antimicrobial mouth rinses (such as chlorhexidine) or warm saltwater rinses. Patients should allow the rinse to fall gently from the mouth rather than vigorously swishing or spitting. [3] Your periodontist will tell you exactly when it is safe to resume brushing and flossing in the treated areas.
You will also be placed on a strict liquid diet for the first three days to avoid disrupting the clot seal, followed by a mushy or soft diet for the remainder of the first one to two weeks. [8] Because there are no sutures holding the gums in place, the shear forces of chewing hard, crunchy, sticky, or seeded foods can dislodge the clot just as easily as a toothbrush. Your periodontist may also provide a bite adjustment (occlusal adjustment) and a temporary splint if any teeth are mobile.
Follow-up visits are critical. Your periodontist will typically see you at one week, one month, three months, and six months post-procedure to measure healing progress. Ongoing periodontal maintenance cleanings, usually every three months, are essential for long-term results. [1]
LANAP Cost and Insurance Considerations
LANAP typically costs more per session than traditional periodontal surgery, though total treatment costs depend on several factors.
As of 2025, the cost of LANAP treatment generally ranges from $5,000 to $15,000 for a full mouth, depending on the number of teeth involved, the severity of disease, geographic location, provider expertise, and whether advanced sedation is used. [10] Some periodontists charge per quadrant (one-quarter of the mouth), with per-quadrant fees typically ranging from $1,500 to $4,000. [10] [11] Costs vary significantly by region and case complexity, so these ranges should be used as a starting point for your own research.
Insurance coverage for LANAP varies widely. Some dental PPO insurance plans cover it under their periodontal surgery benefit using standard ADA procedure codes, often reimbursing $750 to $1,800 per quadrant subject to individual plan deductibles and annual maximums. [10] [11] Other plans classify it as an alternative or experimental procedure and offer reduced reimbursement or no coverage at all. Before scheduling, ask your periodontist's office to submit a pre-authorization or predetermination to your insurance company. This gives you a written estimate of what the plan will cover.
If insurance does not fully cover the procedure, many periodontal offices offer payment plans or accept third-party financing through services like CareCredit. When comparing costs, factor in the potential for fewer follow-up surgical visits, less time off work, and reduced need for pain medication, as these indirect costs can add up with more invasive surgical approaches.
When to See a Periodontist for LANAP
A periodontist is the right specialist to evaluate whether LANAP is appropriate for your specific situation. [1]
Your general dentist may refer you to a periodontist if you have pocket depths of 5 millimeters or greater, visible bone loss on X-rays, bleeding gums that have not improved with professional cleanings, or loose teeth. These signs indicate moderate to severe periodontal disease that may require surgical intervention. [1] [2]
You should also seek a periodontal consultation if you have been told you need gum surgery and want to understand all of your options. A periodontist who is trained in both traditional surgery and LANAP can give you an unbiased assessment of which approach is likely to produce the best outcome for your specific bone loss pattern and health profile.
Some situations clearly favor traditional surgery: teeth with severe furcation involvement, areas needing significant bone grafting, or cases where tissue must be repositioned for access. A skilled periodontist will explain why one approach is recommended over another and will not apply the same treatment to every patient. If a provider recommends LANAP without performing a full periodontal evaluation including probing and current X-rays, consider seeking a second opinion.
