What Is Peri-Implantitis?
Peri-implantitis is an inflammatory condition that affects the tissues around a dental implant. It starts with bacteria building up along the implant surface, triggering an immune response that damages the surrounding gum and bone. Unlike gum disease around natural teeth, peri-implantitis can progress faster because implants lack the protective fiber attachment that natural teeth have.
The condition develops in two stages. The first stage, called peri-mucositis, involves inflammation of the soft tissue (gums) around the implant without any bone loss. Peri-mucositis is reversible with professional cleaning and improved home care. If peri-mucositis is not treated, it can progress to peri-implantitis, where the infection spreads to the bone. Once bone loss begins, the condition is no longer fully reversible, though it can be managed and stabilized.
Peri-Implantitis vs. Peri-Mucositis
Understanding the difference between these two conditions is important because it affects treatment decisions and outcomes.
- Peri-mucositis: Inflammation limited to the gum tissue around the implant. No bone loss on X-rays. Gums may bleed when probed. Fully reversible with professional cleaning and improved oral hygiene.
- Peri-implantitis: Inflammation that has spread beyond the gums into the supporting bone. X-rays show measurable bone loss around the implant. Not fully reversible, but progression can be stopped with treatment.
- Peri-mucositis is considered a precursor to peri-implantitis. Catching problems at the peri-mucositis stage gives the best chance of a simple, non-surgical solution.
Symptoms of Peri-Implantitis
Peri-implantitis can develop silently. In its early stages, you may not feel any pain. That is why regular dental checkups with probing around the implant are critical for early detection.
Early Warning Signs (Peri-Mucositis Stage)
- Redness or swelling of the gums directly around the implant
- Bleeding when brushing or flossing near the implant
- Gums that appear darker or puffier than the surrounding tissue
- Slight tenderness when pressing on the gum around the implant
Advanced Symptoms (Peri-Implantitis Stage)
If your implant feels loose, contact your dentist or periodontist promptly. A loose implant usually means significant bone loss has already occurred and the window for treatment is narrowing.
- Gum recession that exposes the metal implant surface or abutment
- Pus or discharge from the gum line around the implant
- A persistent bad taste or odor near the implant site
- Deepening pockets between the gum and the implant (measured by your dentist)
- The implant feels loose or shifts position
- Visible bone loss on dental X-rays
Causes and Risk Factors for Peri-Implantitis
Peri-implantitis is caused by bacterial infection, but several factors increase the likelihood of developing it. Some of these are within your control, while others relate to the implant placement itself.
Patient-Related Risk Factors
- Smoking: Smokers are significantly more likely to develop peri-implantitis. Tobacco reduces blood flow to the gums, impairs healing, and weakens the immune response around the implant.
- Poor oral hygiene: Inadequate brushing and flossing allows bacterial plaque to accumulate on the implant surface, which is the primary trigger for infection.
- History of periodontitis: Patients who had gum disease before getting implants are at higher risk. The same bacteria that caused gum disease around natural teeth can attack implant sites.
- Uncontrolled diabetes: High blood sugar impairs the body's ability to fight infection and slows tissue healing around the implant.
- Systemic conditions or medications: Conditions that suppress the immune system, or medications like certain bisphosphonates, can affect bone health around implants.
How Peri-Implantitis Is Treated
Treatment for peri-implantitis depends on how much bone has been lost and whether the infection is progressing. Your periodontist will assess the severity using probing measurements, X-rays, and clinical examination before recommending a treatment plan.
Non-Surgical Treatment
Non-surgical treatment is typically the first approach, especially when bone loss is mild to moderate. The goal is to remove bacteria from the implant surface and reduce inflammation in the surrounding tissue.
Your periodontist or dental hygienist will perform mechanical debridement, using specialized instruments (titanium curettes, ultrasonic scalers, or air-abrasive devices) to clean the implant surface without scratching it. Scratching the implant surface can create new areas for bacteria to accumulate.
Local antibiotics, such as minocycline microspheres or chlorhexidine gel, may be placed directly into the pocket around the implant. In some cases, systemic antibiotics are also prescribed. Laser therapy is another non-surgical option that some periodontists use to decontaminate the implant surface and promote tissue healing.
Surgical Treatment
When non-surgical treatment is not enough, or when significant bone loss has occurred, surgical intervention may be needed. The specific approach depends on the pattern and extent of bone damage.
Access flap surgery involves lifting the gum tissue to expose the implant surface for thorough cleaning and decontamination. The implant surface is treated with chemical agents or lasers, and the gum tissue is repositioned and sutured.
Bone grafting may be performed at the same time as flap surgery. Your periodontist places bone graft material into the areas of bone loss around the implant, often with a barrier membrane to guide new bone growth. This procedure, called guided bone regeneration, aims to rebuild some of the lost support.
In severe cases where too much bone has been lost, the implant may need to be removed. After the site heals, a new implant can sometimes be placed with additional bone grafting. Your periodontist will discuss whether saving the existing implant is realistic or whether removal gives a better long-term outcome.
How to Prevent Peri-Implantitis
Prevention is far simpler and less costly than treatment. Most cases of peri-implantitis are preventable with consistent home care and regular professional maintenance.
- Brush at least twice daily using a soft-bristled or electric toothbrush. Pay special attention to the gum line around the implant.
- Use floss threaders, interdental brushes, or a water flosser to clean around the implant and under the restoration where a regular toothbrush cannot reach.
- Keep all scheduled maintenance appointments. Your dentist or hygienist should probe around each implant and take periodic X-rays to monitor bone levels.
- If you smoke, quitting is the single most impactful step you can take to protect your implant. Ask your dentist or doctor about cessation support.
- If you have diabetes, keep your blood sugar well controlled. Unmanaged diabetes significantly increases the risk of infection around implants.
- Report any changes early. If you notice bleeding, swelling, or a bad taste around your implant, schedule an appointment rather than waiting for your next regular visit.
Peri-Implantitis Treatment Cost
The cost of treating peri-implantitis varies widely based on the severity of the condition and the type of treatment required. Non-surgical debridement and local antibiotic therapy may cost $300 to $800 per visit. Surgical treatment, including flap surgery with bone grafting, can range from $1,500 to $5,000 or more per implant site. Costs vary by location, provider, and case complexity.
Dental insurance coverage for peri-implantitis treatment varies. Some plans cover periodontal treatment around implants the same way they cover treatment around natural teeth. Others consider implant-related treatment a separate category with different coverage limits. Check with your insurance provider before beginning treatment to understand what is covered.
Untreated peri-implantitis almost always costs more in the long run. Losing an implant and replacing it (including bone grafting and a new implant) can cost $5,000 to $10,000 or more. Early treatment is both clinically and financially the better approach.
When to See a Periodontist for Peri-Implantitis
A periodontist is a dental specialist with 3 additional years of residency training focused on the gums, bone, and supporting structures around teeth and implants. They are the specialists best equipped to diagnose and treat peri-implantitis.
See a periodontist if you notice bleeding, swelling, or recession around an implant. You should also ask for a referral if your general dentist finds deepening pockets or bone loss around an implant during a routine exam. If you have a history of gum disease and are considering dental implants, consulting a periodontist before placement can help reduce your risk of future problems.
Early referral matters. The sooner peri-implantitis is diagnosed and treated, the better the chance of saving the implant and avoiding surgery.
