    About Dr. Eric Linden

    Dr. Eric Linden: An Innovator and Teacher of Laser Dentistry.

    Dr. Eric Linden is a Periodontist with 30 years’ experience in periodontal and implant specialty practice. Over the last 15+ years, he has performed thousands of procedures with very predictable and successful outcomes using several different lasers, including LANAP and new laser protocols for the treatment of periodontal disease and peri-implantitis. He is a Clinical Professor of Periodontics and Implantology at Columbia University School of Dental Medicine and Columbia Presbyterian Medical Center (more). He was the first periodontist to perform Laser Periodontal Surgery (LANAP) in New York City and New Jersey, and is respected by his colleagues as a pioneer in laser periodontics. He also specializes in bone regeneration, dental implants, and biostimulation. When necessary, he employs traditional periodontics. Dr. Linden is often requested to review research, clinical papers, case reports, and manuscripts for publication in the “International Journal of Periodontics & Restorative Dentistry“, Dentistry Today, and Implant Practice – US.


    Dr. Linden is one of the first periodontists in the world to use four types of lasers. Each of has a specific application in the treatment of periodontal disease and peri-implantitis. Dr. Linden uses whichever is most appropriate for each case:

    • ND/YAG, the kind used in LANAP™ & LAPIP
    • Erbium laser
    • CO2 laser
    • Diode laser

    See full story.

    Thanks, in part, to Dr. Linden’s efforts to popularize the laser and instruct others in its use, more and more dental professionals are acquiring and using the technology. There are nearly 1,800 doctors in the world qualified to use the Nd/YAG (neodymium-doped:yttrium, aluminum, and garnet) laser for the advanced treatment of periodontal disease and peri-implant disease. But Dr. Linden is among only 29 officially certified by the Institute for Advanced Laser Dentistry to train and teach other dental professionals in its use.


    He has now helped thousands of patients, treating gum disease, performing tooth extractions, implants, and other periodontal procedures with various dental lasers.

    State-of-the-Art Procedures

    Dr. Linden uses the latest and most innovative diagnostic and therapeutic procedures:

    • Laser Periodontal Therapy (LANAP) and Laser Peri-Implantitis Protocol (LAPIP). Dr. Linden is an innovator and acknowledged expert in the use of these highly effective FDA cleared protocols.
    • DNA and HPV testing to help determine the state of patients’ periodontal health, as well as detect any possible genetic proclivity toward periodontal disease. This testing also checks for the HPV virus. The DNA sample is obtained by rubbing a cotton swab on the inside of the cheek. Analysis is conducted by Oral DNA Labs.
    • The world’s highest quality dental implants, manufactured by Nobel Biocare, BIOMET 3i, and NEOSS. Click here to see animated videos of various implant applications.
    • Digital x rays. This superior technology, using equipment from Dexis Diagnostic Imaging, offers numerous benefits to the patient, including reduced exposure to radiation, less waiting time, shorter appointments, involvement in co-diagnosis, and better understanding of treatment.
    • Enhanced Cosmetic Gum Preservation Therapy – new conservative and non invasive techniques to preserve and maintain an aesthetic smile.

    What is LANAP?

    LANAP is an acronym for “Laser Assisted New Attachment Procedure”.

    Traditionally, moderate to advanced periodontitis, or gum disease, was treated with surgery involving cutting, stitching, and significant recovery time. This invasive approach was often painful, and was contraindicated for patients taking medications such as blood thinners, certain cardiac medications, and other systemic medications. Although traditional procedures have been successful, LANAP is

    • less invasive
    • more conservative
    • more predictable
    • state-of-the-art
    • not painful, with no cutting, stitching, or bleeding
    • superior to traditional techniques in promoting bone regeneration

    It should be made clear that LANAP does not emit ionizing radiation, as do x-rays. We have treated pregnant patients with lasers safely for many years without any issues. To make the point perfectly clear, we administer the laser treatment without any lead shielding, as there is no harmful radiation whatsoever.

    LANAP/Laser Surgery Videos

    New Jersey TV NEWSChannel 12 recently taped a medical segment with Dr. Linden, including video of him performing LANAP on a live patient, and an interview discussing laser treatment, gum disease, and its systemic connections, causes, treatment, etc.

    Ask a Question
    Recent Q&A's :

    I had to have a front and eye tooth pulled. Since February of 2016, I've had three different procedures: a gum graft, bone graft, and then a ridge augmentation. With each procedure, the gum got progressively worse such that I wound up with a gaping hole with the titanium ridge showing. The periodontist said he can't do any more for me, and actually refunded my money. He suggested I see an oral surgeon, which I did, but he said there is nothing he can do. So now it’s in the hands of my dentist and the lab for me to get the best look I can. The good thing is that my gums do not show when I smile. I'm sorry I didn't work with the original shrinkage, and get the best result I could. Do you think there is any hope for me to achieve a good gum graft?
    Several different professionals have examined you and worked with you in person, so I’m afraid that having not examined you myself, I can’t offer Continue..

    I had combination of pinhole surgery and gum graft a year and half ago to repair gum recession caused by aggressive flossing. However, after the surgery, the gums didn't elongate back to the original height, though they did somewhat. The periodontist explained this is in part because the gums will only cover the tooth as much as there is bone support. Ideally, I would like the gums to "come down" another 2mm. Is there any type of surgery or new advancement that could improve my "long in the tooth" appearance?
    There’s a secondary procedure called “Coronally Advanced Flap” that involves moving the gum up and down, like the blinds on a window. A qualified Continue..

    Have you used LANAP for removal of a blue spot on a lower lip? Are there any side effects? What kind of recovery issues can be expected? Thanks very much.
    Yes, we have removed spots off of lips using the laser, with great success. Usually there is a healing period after any surgical procedure and th Continue..

    I'm fifty years old, have osteopenia, and naturally thin gums. I have always taken very good care of my teeth. I have had three rounds of orthodontia, two in my late teens and the last when I was in my late thirties. I have generalized recession and some bone loss. I don't have periodontal disease and never have. I've had six gum grafts - four with connective tissue (upper teeth) and two free gingival (on my lower teeth). Aesthetically, I have some very small black triangles between all of my front teeth and larger ones on the sides and between my molars. Functionally, the gaps between my teeth collect food. Is LANAP a possibility to help regenerate bone around and between my teeth? Would my papillae be preserved? If bone is regenerated, do the gums "grow" along with the bone and produce a more aesthetic look? I would like my teeth to look better, though I'm not sure that is possible. However, I definitely do not want them to look worse. I also do not want to lose any teeth. What are your thoughts? Thank you for your response.
    Anybody who has generalized recession and bone loss needs a complete periodontal evaluation, with x-rays and clinical measurements. If you have b Continue..

    How long until the tight discomfort of an AlloDerm gum graft goes away? I had a gum graft on 8 lower front teeth due to thinning gums. The procedure was done last week and the tight unnatural feeling is driving me crazy. Please help. Thank you!

    I need a lot of work in my gums. I have so much pain in my jaw and my right ear. I think it’s because my gums are infected. I also have really bad breath.

    I have a permanent denture on four implants on my bottom jaw. It was done three years ago and I am now having a lot of pain were the implant is. I'm concerned.
    I would certainly recommend checking back with your Periodontist who placed the implants as well as the restorative dentist who made your denture Continue..

    I have upper dentures that literally fall out of my mouth. I need a sinus lift and bone regeneration. Plus 6 implants. I was told $20,000 for the lift and bone regeneration and $19,000 for the denture. My bottom teeth are not in good shape but I will not have them done for fear of not keeping any denture in my mouth. I do use adhesive but they loosen very fast. I can't afford $40,000 for my top and God knows what the bottom will cost. Are your procedures just as expensive? And what do you see as my options?
    I can answer general questions online, but I cannot accurately or responsibly answer your specific questions without a professional examination, Continue..

    Dr. Linden, I have three questions:
    I had 'traditional' laser treatment in November which helped for a while. In April I went back to the same dentist, who did a gingival flap root planing. This actually worsened the situation and felt too invasive. Then my regular dentist referred me to LANAP treatment, which I did last week.
    Was it ok to have LANAP only one month after flap root planing?
    Out of excitement or whatever reason, I did not properly read or listen to post-op instructions and only followed a soft diet and not a liquid diet for the first 24 hours. I did not chew in any way on the treated side, but now, reading about the importance of the blood clots, I am afraid I undid a large part of the treatment or made it much less effective. How concerned should I be? Does the treatment have to be redone?
    Thanks for your answer.

    In general, we don’t do scaling or root planing before LANAP, but there may always be individual exceptions to general rules. Your periodontist e Continue..

    I had two LANAP treatments, one half mouth on 4/14 and the other half on 4/21. When can I have a glass of wine?
    If you are on a medication which should not be mixed with alcohol, then you should not drink wine. If you are not on any such medication, then ha Continue..

    I had LANAP done 4/25/16 and stuck to the soft diet, but when I ate a soft piece of bread four days later I noticed the white clot around a molar was gone. I am afraid I undid the clot and the tooth may get re-infected. If so, what can be done?
    I would suggest that you have your periodontist take a look at the area in question and determine if anything needs to be done. Continue..

    What is the average cost of full mouth laser surgery? What is lowest the procedure can cost and what is the highest?
    The best solution for the treatment of gum disease is based on an accurate diagnosis, comprehensive examination, and review of a quality set of d Continue..

    How is it determined whether or not tissue is diseased? I believe I have some pale-colored, unhealthy tissue between my teeth. Will LANAP work on this type of tissue even if it's not reddened?
    The laser targets diseased tissue. If the laser periodontist uses the appropriate settings, then the procedure will be successful The tissue does Continue..

    I have a very slight history of cavities over the last several years. But, I had LANAP procedure on all of my teeth December 2014/January 2015 primarily because my teeth were becoming somewhat loose. All of 2015 I was seeing the periodontist for monthly/bi-monthly visits, and I was released in January 2016. X-rays were taken in January 2016 showing I had 5 cavities, two of them under existing crowns. My dentist filled the cavities in March 2016. Now, in the middle of April I went in for a cleaning and learned that I have two more cavities (found by the dental tech during the cleaning). I hardly ever had cavities, but now since LANAP - Seven Cavities? Is there a correlation?
    Neither my extensive experience nor any known research has ever shown a correlation between LANAP and cavities. Perhaps the extra attention given Continue..

    I'm told that my tooth #9 sits in less than 50% of normal bone. Am I a candidate for bone regeneration? The tooth doesn't hurt, although I do treat it very carefully, e.g., if I am called to bite down with front teeth, I bite (also carefully) with #8 only. Thank you.
    Every situation is different. You may be a candidate, but I cannot answer confidently without seeing your x-rays and examining you. Continue..

    If I need a bone graft during flap surgery (recommended by my periodontist) and she plans to use human cadaver bone, is there a risk of infectious disease or rejection? There is only a little bone loss. Won't I develop some bone growth without the graft? The bone loss is not at the roots.
    Cadaver Bone grafts are safe as long as the bone is purchased from a licensed vendor. Each bone batch is labeled and sealed with tracking numbers Continue..

    What can a person do if they need a gum graft but they were told there is not enough blood supply to effectively get one? This is a graft that effects the person’s confidence when they speak and smile and needs to be done in the very front of this person’s mouth above one of her front teeth that is an implant.
    Anybody can get a graft wherever it is needed. The question is whether the graft would go over the root surface, and whether it’s the right choic Continue..

    I am 68 years old only have 3 bottom teeth grouped together. I was thinking of getting implants but would rather keep the 3 teeth with a new partial denture. What would I need to do to hold on to those 3 teeth? What is your recommendation?
