Peri-Implantitis Symptoms, Causes, Diagnosis, Treatment

Peri-implantitis is an inflammatory disease around a dental implant that can destroy the bone supporting the implant if left untreated. It is the implant equivalent of severe gum disease, and if you have dental implants, it is the single most important complication to know about and prevent.

The good news is that peri-implantitis is treatable in most cases when caught early. The key is recognizing symptoms before bone loss becomes advanced, since severe cases can eventually lead to implant failure. This page covers what causes it, how to spot it, and what peri-implantitis treatment actually looks like.

Symptoms of Peri-Implantitis

Early peri-implantitis often has no symptoms at all, which is why regular implant checkups matter. When symptoms do appear, they resemble gum disease around the implant:

• Red, swollen, or tender gum tissue around the implant
• Bleeding when brushing or flossing near the implant
• Pus or discharge from the gum edge
• A bad taste or smell that does not go away with brushing
• Gum recession exposing metal threads of the implant
• The implant feeling loose (advanced stage)

A related but milder condition called peri-implant mucositis affects only the soft tissue and has not yet destroyed bone. Mucositis is fully reversible if treated. Peri-implantitis, by contrast, involves bone loss and requires more active intervention.

What Causes Peri-Implantitis

Peri-implantitis is caused by bacteria that colonize the surface of an implant and the surrounding gum tissue. Certain factors dramatically raise the risk:

• Smoking: smokers have roughly twice the rate of peri-implantitis
• Poor oral hygiene: cement and plaque left around implant crowns
• Untreated periodontal disease in your natural teeth
• Uncontrolled diabetes or other conditions affecting healing
• Occlusal overload: excess bite force on the implant crown
• Excess cement left below the gumline from crown placement

Genetic susceptibility to gum disease also plays a role. Patients who lost their natural teeth to gum disease should be monitored more closely once they have implants.

How Peri-Implantitis Is Diagnosed

Diagnosis combines a clinical exam and imaging. A periodontist will:

1. Probe gently around the implant to measure pocket depths (over 4 mm around an implant is a warning sign)
2. Check for bleeding on probing
3. Take a periapical x-ray or CBCT scan to measure bone level around the implant
4. Compare bone levels to baseline images taken when the implant was first placed

The formal diagnosis requires bone loss beyond the initial remodeling that happens in the first year after placement. This is why baseline imaging at implant placement is so valuable.

Peri-Implantitis Treatment Options

Peri-implantitis treatment follows a ladder from least to most invasive, matched to how much bone loss has occurred.

Non-Surgical Treatment

For mild cases and peri-implant mucositis, we perform a thorough professional decontamination of the implant surface. This includes:

• Mechanical debridement with titanium or plastic instruments (metal instruments can scratch the implant surface)
• Air-polishing with glycine powder to remove biofilm
• Local antimicrobial delivery (chlorhexidine gel or antibiotic microspheres)
• Reinforcement of home care technique with special brushes and floss

Non-surgical treatment often stops early disease and reverses mucositis completely.

Surgical Peri-Implantitis Treatment

When bone loss is moderate to severe, surgical access is needed to fully clean the implant surface and, when possible, regenerate lost bone. Techniques include:

• Open-flap debridement: the gum is temporarily lifted to expose and clean the entire implant surface
• Resective surgery: reshaping bone to eliminate deep pockets
• Regenerative surgery: placing bone graft material and a membrane to rebuild lost bone around the implant
• Laser decontamination: using an Er:YAG or diode laser to sterilize the implant surface without damaging titanium

In cases where the implant has already lost more than half its supporting bone or is mobile, the honest answer is that removal and replacement is often more predictable than trying to save it.

How to Prevent Peri-Implantitis

Prevention is far easier than treatment. Best practices include:

• Brush around implants twice daily with a soft or electric toothbrush
• Use interdental brushes or floss designed for implants
• Attend periodontal maintenance visits every 3 to 4 months, not standard 6-month cleanings
• Do not smoke
• Control diabetes and treat any active gum disease in natural teeth
• Have the periodontist check your implant crowns for excess cement

Frequently Asked Questions

Can peri-implantitis be cured?

Mild cases and mucositis are fully reversible with cleaning and better home care. Moderate cases can usually be stabilized, though lost bone does not fully return without regeneration. Severe cases may require implant removal.

How much does peri-implantitis treatment cost?

Non-surgical treatment typically runs $300 to $800 per implant. Surgical treatment with regeneration ranges $1,500 to $3,500 per implant. Insurance sometimes covers surgical care under periodontal codes.

How long does peri-implantitis treatment take to heal?

Non-surgical care shows improvement within 4 to 6 weeks. Surgical treatment involves 2 to 4 weeks of soft-tissue healing followed by 4 to 6 months of bone consolidation before final follow-up imaging.

Will my implant fall out from peri-implantitis?

Only in advanced, untreated cases. Most implants can be saved if the disease is caught before more than one-third of the supporting bone is lost.

Consult in DC, Alexandria, or Reston

If you have symptoms of peri-implantitis or your general dentist has flagged concerns about your implant, do not wait. Early peri-implantitis treatment is dramatically more effective than late-stage intervention. Request a consult at our Washington DC, Alexandria, or Reston office and we will image your implant, measure the bone level, and give you a straightforward plan.
