Peri-implantitis is an inflammatory condition that affects the tissues surrounding a dental implant, characterized by progressive loss of the supporting bone. It is the implant equivalent of periodontitis, the severe form of gum disease that destroys bone around natural teeth. While dental implants cannot develop cavities, they are susceptible to bacterial infection of the surrounding tissues, and when that infection reaches the bone, it creates a destructive cycle that can ultimately lead to implant failure and loss if not treated by a specialist.
The condition begins as peri-implant mucositis, an inflammation of the soft tissue around the implant without bone involvement. Peri-implant mucositis is reversible with proper treatment, much like gingivitis is reversible around natural teeth. However, when mucositis is left untreated, the bacterial infection can penetrate deeper and begin destroying the bone that anchors the implant. Once bone loss occurs, the condition is classified as peri-implantitis, and it requires more intensive intervention to halt the destruction and, when possible, regenerate lost bone.
Research indicates that peri-implantitis affects approximately 20 to 30 percent of dental implant patients to some degree within 5 to 10 years of implant placement. Given the growing number of implants placed each year, peri-implantitis has become one of the most significant challenges in implant dentistry. For Orange County patients experiencing signs of implant trouble, early evaluation by a board-certified periodontist offers the best chance of saving the implant and avoiding the expense and inconvenience of replacement.
Recognizing peri-implantitis early dramatically improves treatment outcomes. Unfortunately, the condition can progress with subtle or no symptoms in its early stages, which is why routine monitoring by a periodontist is essential for implant patients. When symptoms do appear, they may include one or more of the following.
Silent Progression: One of the most dangerous aspects of peri-implantitis is that it can destroy significant bone without causing pain. Unlike a tooth infection that often produces a toothache, implant infections may progress silently because the implant itself has no nerve supply. By the time patients notice a problem, substantial bone may already be lost. This is why Dr. Ahn recommends that all implant patients have their implants professionally evaluated with probing measurements and periodic X-rays at least once per year.
Peri-implantitis treatment requires specialized knowledge of implant surface biology, bone regeneration techniques, and surgical access to contaminated implant surfaces. A board-certified periodontist has completed three additional years of surgical residency training beyond dental school focused specifically on the hard and soft tissues that support teeth and implants. Dr. Chanook David Ahn brings an additional advantage: having placed over 5,000 dental implants himself, he has an intimate understanding of implant design, surface characteristics, bone integration patterns, and the surgical anatomy involved.
General dentists and even some implant providers may not have the specialized training to surgically treat peri-implantitis. Non-surgical approaches like antibiotics and localized rinses can help manage early-stage disease, but once bone loss has occurred, surgical intervention is almost always necessary to access the contaminated implant surface, remove infected tissue, decontaminate the implant, and place bone graft material to regenerate lost support. These are advanced periodontal surgical techniques that require residency-level training.
Treatment for peri-implantitis is staged based on the severity of the disease. Dr. Ahn evaluates each case individually using clinical probing measurements, CBCT 3D imaging, and assessment of the overall implant stability to determine the most appropriate treatment approach.
For early-stage peri-implantitis or peri-implant mucositis where bone loss is minimal, non-surgical treatment may be effective. This includes mechanical debridement of the implant surface using specialized instruments designed to clean implant surfaces without scratching the titanium, localized antimicrobial therapy delivered directly into the pocket around the implant, systemic antibiotics when indicated to address the bacterial infection, and reinforcement of the patient's home care techniques with implant-specific hygiene instruction. Non-surgical treatment is often the first line of defense and may be sufficient to resolve inflammation and stabilize the condition when caught early.
When significant bone loss has occurred, surgical access is required to effectively treat peri-implantitis. Dr. Ahn raises a tissue flap to expose the implant surface and the surrounding bone defect. The infected granulation tissue is removed, and the contaminated implant surface is thoroughly decontaminated using a combination of mechanical cleaning, chemical agents, and in many cases LANAP laser energy. Once the implant surface is clean, bone graft material is placed into the defect to regenerate lost bone. A barrier membrane may be used to protect the graft and guide bone formation. The tissue is then repositioned and sutured.
The LANAP (Laser-Assisted New Attachment Procedure) protocol uses a specialized Nd:YAG laser that selectively targets diseased tissue and bacteria while preserving healthy tissue. Dr. Ahn incorporates LANAP into peri-implantitis treatment when appropriate, using the laser to decontaminate the implant surface and the surrounding pocket. The laser energy destroys bacterial colonies, removes infected tissue, and creates a stable blood clot that promotes healing. LANAP can be used as a standalone treatment for moderate cases or in conjunction with surgical bone grafting for more advanced disease. Learn more about our LANAP laser treatment.
One of the most challenging aspects of peri-implantitis treatment is decontaminating the implant surface. Unlike a natural tooth root, which has a relatively smooth surface, dental implants have textured surfaces designed to promote bone integration. These textured surfaces, while excellent for initial bone attachment, create microscopic hiding places for bacteria once infection occurs. Dr. Ahn uses multiple decontamination methods tailored to the specific implant surface type, including air-powder abrasive devices, citric acid application, chlorhexidine irrigation, and laser energy. The goal is to remove the bacterial biofilm completely so the bone graft can integrate with a clean implant surface.
Having placed over 5,000 implants, I understand implant anatomy from both the placement and the rescue perspective. When I treat peri-implantitis, I know exactly how the implant was designed to integrate with bone, what the thread geometry looks like at a microscopic level, and how the surface treatment affects bacterial adhesion. This knowledge allows me to choose the most effective decontamination protocol for each specific implant system. Peri-implantitis treatment is not one-size-fits-all. The approach must be tailored to the implant type, the pattern of bone loss, and the patient's overall health. My goal is always to save the implant when the prognosis is favorable, and to be honest with patients when replacement is the better long-term option.

Peri-implantitis is caused by bacterial infection around a dental implant that triggers an inflammatory response and progressive bone loss. The primary cause is bacterial biofilm accumulation on the implant surface, similar to how plaque causes gum disease around natural teeth. Contributing factors include inadequate oral hygiene, smoking, uncontrolled diabetes, a history of periodontal disease, poorly positioned implants, excess cement left beneath the gum line during crown placement, and insufficient attached keratinized tissue around the implant. Patients who had periodontal disease before receiving implants are at significantly higher risk.
In many cases, yes. The success of treatment depends on how much bone has been lost around the implant, the pattern of bone loss, and whether the implant is still stable. When peri-implantitis is caught early to moderately, treatment involving implant surface decontamination and bone grafting can halt the disease and regenerate lost bone. Dr. Ahn evaluates each case with CBCT 3D imaging to assess the exact pattern and extent of bone loss. If more than 50 to 60 percent of the bone support has been lost or the implant is mobile, removal and eventual replacement may be the better long-term solution. Early intervention provides the best chance of saving the implant.
Common signs of peri-implantitis include red, swollen, or tender gums around the implant; bleeding when brushing or probing around the implant; deepening pockets between the gum and the implant; pus or discharge from the gum around the implant; a bad taste or persistent bad breath localized to the implant area; and visible recession of the gum tissue exposing the implant threads or metal collar. In advanced cases, the implant may feel loose. However, peri-implantitis can progress silently with minimal symptoms, which is why regular dental check-ups with probing and periodic X-rays are essential for early detection.
Peri-implantitis treatment costs vary based on the severity of the condition and the treatment approach. Non-surgical treatment with mechanical debridement and antimicrobial therapy typically ranges from $500 to $1,500 per implant. Surgical treatment involving flap access, implant surface decontamination, and bone grafting ranges from $2,000 to $5,000 per implant depending on the extent of bone loss and the grafting materials required. LANAP laser-assisted treatment may add $500 to $1,500. The Loft Dental Studio provides detailed treatment estimates after a thorough evaluation including CBCT imaging.
Many PPO dental insurance plans cover a portion of peri-implantitis treatment because it is a medically necessary procedure to treat infection and prevent implant loss. Coverage typically falls under the periodontal surgery benefit category, with reimbursement ranging from 50 to 80 percent of the allowed fee depending on your plan. Some plans may require documentation of the medical necessity before approving coverage. The Loft Dental Studio accepts most major PPO plans including Delta Dental, Cigna, MetLife, Guardian, Aetna, United Healthcare, and Blue Cross Blue Shield. Our team verifies your benefits and obtains any needed pre-authorizations before treatment begins.
Preventing peri-implantitis requires consistent daily oral hygiene around the implant, including brushing twice daily with a soft-bristle brush, daily flossing or using an interdental brush around the implant, and using an antimicrobial mouth rinse as directed. Regular professional cleanings every 3 to 4 months are recommended for implant patients, as specialized instruments are needed to clean implant surfaces without scratching them. Avoiding smoking is critical because tobacco use dramatically increases peri-implantitis risk. Managing systemic conditions like diabetes also reduces risk. Dr. Ahn also evaluates whether adequate keratinized tissue exists around each implant, as insufficient tissue makes cleaning difficult and increases infection susceptibility.
