Implant Surgery & Support
Peri-implantitis
An inflammatory condition affecting the tissue and bone around a dental implant — the implant equivalent of periodontitis, and the leading cause of late implant loss.
Why it is dangerous
Peri-implantitis is a bacterial infection that progressively destroys the bone supporting an implant, and can lead to implant loss if left untreated.
The critical problem is that it usually develops without obvious symptoms. By the time signs appear — swelling, bleeding, deepening pockets, or mobility — substantial bone loss may already have occurred. This is why regular monitoring matters more with implants than most patients expect.
Risk factors
Bacterial Buildup
The primary cause. Unlike natural teeth, which have a periodontal ligament, implants fuse directly to bone — so when infection takes hold, bone loss can be rapid and severe. Poor oral hygiene allowing bacterial biofilm to accumulate is the most common route in.
History of Gum Disease
Patients with previous periodontitis carry higher risk, because they harbour more aggressive bacteria and may have compromised bone healing. The same organisms that attacked your natural teeth will attack the tissue around an implant.
Smoking & Systemic Health
Smoking impairs bone healing and increases bacterial load. Diabetic patients experience higher failure rates. Stress, poor nutrition, and infrequent professional cleanings all contribute through their effect on immune function.
Poor Fit & Positioning
Implants placed too close to sinuses or other structures may have insufficient bone support. Overloading before full integration damages the bone-implant interface. Poor crown design creates plaque traps that harbour bacteria.
Signs to watch for
Early detection significantly improves treatment outcomes. Most of these are picked up at routine maintenance appointments before you would notice them.
- ✓ Swelling or redness around the implant
- ✓ Bleeding during brushing or flossing
- ✓ Increasing pocket depth measured at hygiene visits
- ✓ Discomfort or pain around the implant
- ✓ Visible implant mobility — a late and serious sign
