Peri-implantitis is one of the most serious complications of dental implants. Fortunately, it is completely preventable with good hygiene and regular follow-up. This article explains everything you need to know.
Peri-implantitis is a bacterial infection of the tissues surrounding a dental implant. It is the equivalent of periodontitis (gum infection) but around an implant instead of a natural tooth.
Important difference:
- Gingivitis/Periodontitis = infection around natural tooth
- Peri-implantitis = infection around implant
Why is it more serious with implants? Unlike a natural tooth which has a "shock absorber" (periodontal ligament), the implant is directly fixed in the bone. Therefore, infection can progress very quickly toward the bone, risking destruction of bone fusion and implant loss.
Early warning signs:
- Bleeding gums around the implant
- Swollen or red gums
- Pain or sensitivity
- Pus discharge
- Persistent bad breath
- Bad taste in mouth
Advanced signs (late):
- Crown mobility
- Implant mobility (very serious)
- Bone loss visible on X-rays
- Pain when chewing
- Significant gum swelling
Warning: Peri-implantitis can be SILENT. You may have NO SYMPTOMS while infection progresses!
Cause 1: Insufficient oral hygiene (60% of cases)
- Accumulation of bacterial plaque
- Inadequate brushing
- No flossing
- Tartar accumulation
Cause 2: Aggressive specific bacteria (30% of cases)
- Porphyromonas gingivalis
- Tannerella forsythensis
- Prevotella intermedia
- These bacteria destroy bone
Cause 3: Previous periodontal disease (80% of peri-implantitis)
- If you had periodontitis, risk is very high
- Same aggressive bacteria present
- Same genetic predisposition
- Important: treat before implant
Cause 4: Smoking (25-50% of cases)
- Reduces blood circulation
- Weakens immune system
- Reduces healing
- Double risk combined with poor hygiene
Cause 5: Uncontrolled diabetes
- Weakens immune response
- Bacteria multiply faster
- Healing delayed
- Important: balance blood sugar
Cause 6: Overloading (excessive bite force)
- Excessive force on implant
- Micro-movements
- Breaking of seal
- Bacteria infiltrate
Cause 7: Poor surgical technique
- Implant not well integrated
- Gap between crown and implant
- Bacterial niches
- Rare with good surgeon
Cause 8: Contaminated material
- Infection at time of placement
- Very rare (1%)
- Sign: immediate post-op infection
BEFORE IMPLANT:
Complete periodontal treatment (if periodontitis)
- Professional scaling
- Pocket curettage
- Antibiotic therapy if necessary
- Wait for complete healing (3-6 months)
Stop smoking
- Minimum 2-4 weeks before
- Ideally 1-2 months before
- Increases success 25-40%
Balance diabetes
- Hemoglobin A1c < 7%
- Better circulation
- Better healing
Improve oral hygiene
- Learn proper techniques
- Use adapted brushes
- Daily flossing
DURING PLACEMENT:
Experienced surgeon
- 22+ years experience recommended
- Sterile technique respected
- Implant well integrated
3D guided technique
- Position calculated exactly
- Optimal depth
- Perfect angle
- Superior quality
Quality implants
- Recognized brands (Nobel, Straumann)
- Special surface for fusion
- Manufacturer warranty
- Higher price = long-term investment
AFTER IMPLANT:
Impeccable hygiene (criterion #1)
- Brushing 2x daily with SOFT brush
- Flossing EVERY DAY around implant
- Antiseptic mouthwash 2-3x/day
- Interdental cleaning with brushes
Regular professional follow-up
- Check every 3 months (year 1)
- Then every 6 months minimum
- Professional cleaning every 3-6 months (vs annual normal)
- Annual radiographs
No smoking
- Permanent cessation after implant
- Even small amounts problematic
- Reduces circulation 40%
Balanced nutrition
- Calcium and vitamin D
- Proteins for healing
- Reduce inflammation
Stress management
- Stress = weak immunity
- Sufficient sleep (7-8h)
- Regular exercise
No bruxism
- If you clench teeth: mouthguard
- Reduces overloading
- Extends implant life
EARLY DIAGNOSIS
How do we detect peri-implantitis?
1. Clinical examination:
- Gentle pocket probing
- Bleeding check
- Implant mobility
- Visual inspection
2. X-rays:
- Periapical radiograph
- Panoramic for overview
- Shows bone loss in mm
- Compare with initial radiograph
3. Biological tests (advanced):
- Bacterial DNA test
- Count specific bacteria
- Determines bacteria type
- Guides antibiotic treatment
4. 3D scan (if doubt):
- Exact bone view
- Extent of destruction
- Treatment planning
Key: Early detection = easier treatment
MILD STAGE (Early detection):
Non-surgical treatment (first line):
- Aggressive professional cleaning (curettage)
- Scaling and root planing
- Antiseptic solution rinse
- Adapted antibiotics (test if possible)
- Drastic hygiene improvement
Result: 40-60% success if caught early
Follow-up: Every 2 weeks, then monthly
MODERATE STAGE (With slight bone loss):
Surgical treatment necessary:
- Complete scaling (seen earlier)
- Bone regeneration surgery possible
- Regeneration membrane
- Filling materials
- Sutures
- Antibiotics
Result: 60-75% success with modern technique
Recovery: 1-2 months
Limited options:
Option A: Recovery attempt
- Complete surgery
- Aggressive bone regeneration
- Uncertain result
- High cost
Option B: Implant extraction
- Implant not salvageable
- Removal and bone graft
- Reimplantation after 4-6 months
- Total cost higher
- But better long-term
Decision: With you and your dentist
Commonly prescribed antibiotics:
- Amoxicillin 500mg 3x/day (7-10 days)
- Metronidazole 250mg 3x/day (for anaerobes)
- Combination of both (better efficacy)
- Dose/duration according to bacteria detected
Important: Complete treatment (even if better before end)
Contraindications: Penicillin allergy? Alternatives available
Patient: Mr. H., 55 years old

Diagnosis:
- X-ray: 3mm bone loss
- Probing: 4-5mm pockets

1. Intensive professional curettage
2. Antibiotics: Amoxicillin + Metronidazole
3. Strict hygiene instructions
4. Mandatory flossing
5. Smoking cessation
