Peri-implantitis:
act on tissue change before bone loss advances.
Bleeding or swelling around an implant is not normal maintenance. Peri-implant disease needs clinical assessment to distinguish reversible mucosal inflammation from bone-involving disease.
Peri-implant mucositis versus peri-implantitis
Both involve inflammation around an implant, but peri-implantitis includes progressive supporting-bone loss.
Peri-implant mucositis is inflammation confined to the soft tissues around an implant and commonly presents with bleeding on probing; it can improve when causes are controlled. Peri-implantitis is a plaque-associated pathological condition with inflammation and progressive loss of supporting bone beyond expected initial remodelling. A photograph or symptom list cannot distinguish them reliably. The clinician compares current probing and radiographic findings with baseline records, considers implant position and restoration design and excludes other causes. The word ‘infection’ is often used loosely online, but accurate classification matters because management and prognosis differ.
Mucositis
Soft-tissue inflammation without the progressive supporting-bone loss that defines peri-implantitis.
Peri-implantitis
Inflammation with progressive peri-implant bone loss and a more complex treatment pathway.
Other problems
Cement, food trapping, fracture, overload, endodontic or neighbouring-tooth disease may mimic symptoms.
Peri-implantitis signs and warning symptoms
Bleeding can be an early signal; pain or mobility may appear only after substantial disease or another complication.
Possible signs include bleeding during cleaning or probing, swelling, redness, suppuration, unpleasant taste, increasing probing depth, recession or visible implant threads. Pain is not required. Implant mobility is particularly concerning because a bone-integrated fixture should not move; however, a loose crown or screw can feel similar and must be distinguished. Rapid facial swelling, fever, spreading redness, difficulty swallowing or breathing, uncontrolled bleeding or severe systemic illness require urgent local assessment. Do not wait for a distant clinic to reply before seeking emergency care.
Arrange assessment
Persistent bleeding, swelling, discharge, bad taste, recession or new cleaning difficulty.
Prompt review
New pain, bite change, apparent movement or a rapidly worsening local problem.
Urgent care
Airway or swallowing difficulty, spreading swelling, fever with illness or uncontrolled bleeding.
How peri-implantitis is diagnosed
Diagnosis uses clinical examination and appropriately indicated imaging, ideally compared with baseline data.
The clinician records bleeding or suppuration, probing depths and recession using careful technique, assesses plaque and cleaning access, checks implant and restoration mobility and evaluates the bite and prosthetic design. Radiographs are selected to show bone levels and compared with earlier images when available. Implant placement, excess cement, component fit, restoration contour and systemic or behavioural risks are reviewed. A single deep measurement or radiograph without context should not be used to label disease. The assessment also determines whether the restoration can be removed or modified to allow treatment and daily hygiene.
Clinical measures
Bleeding, suppuration, probing, recession, plaque, tissue appearance and mobility.
Radiographic comparison
Bone-level change interpreted against baseline remodelling, image geometry and clinical findings.
Cause analysis
Cleanability, prosthetic contour, position, cement, smoking, periodontal history and maintenance.
Peri-implantitis treatment options
Management starts by controlling inflammation and modifiable causes, then reassesses whether surgery is indicated.
Current guideline pathways emphasise oral-hygiene instruction and risk-factor control, professional decontamination and correction of cleanability or prosthetic problems where possible. Non-surgical treatment is followed by reassessment. Persistent deep pockets, bleeding, suppuration or bone defects may lead to surgical access, resective or regenerative approaches in selected cases. No single surface-decontamination method or graft guarantees success. Implant removal may be discussed when disease is advanced, the implant is mobile or fractured, position prevents maintainability, or prognosis is unacceptable. The treating team should explain alternatives, limitations, maintenance and what outcome would trigger a change of plan.
Initial phase
Education, plaque control, professional instrumentation and correction of local risk factors.
Reassessment
Measure tissue response and decide whether residual disease needs surgical access.
Advanced decision
Select surgical care, maintenance or implant removal according to defect, position and prognosis.
Reduce peri-implantitis risk and recurrence
Stable periodontal health, cleanable restoration design and supportive care are core long-term safeguards.
Before implant treatment, active gum disease should be controlled and the patient should be able to clean the proposed restoration. After placement, establish baseline clinical and radiographic records, demonstrate site-specific hygiene and set a risk-based maintenance interval. Smoking cessation support, diabetes control and management of other relevant health factors may improve the risk environment. At every review, look for bleeding, plaque, tissue or bone change and technical problems rather than waiting for pain. After peri-implantitis treatment, supportive care is essential because recurrence remains possible. If treatment was completed abroad, identify a local clinician willing to provide supportive care and give that clinician the baseline radiographs, component record and operative summary. A remote photograph may help triage communication but cannot replace probing, mobility testing or appropriate imaging.
Before implant
Control disease, assess risk, position for restoration and design realistic hygiene access.
After restoration
Record baseline, teach cleaning and monitor tissues, bone and components.
After treatment
Maintain frequent supportive care initially and adapt the interval to response and risk.
A peri-implant assessment and handover record
Give the clinician enough information to identify change and maintain compatible components.
Before commitment, confirm that:
- ✓ Implant brand, platform, position, placement date and restoration design are known.
- ✓ Baseline and current radiographs can be compared where clinically appropriate.
- ✓ Bleeding, probing, recession, suppuration, mobility and plaque are documented.
- ✓ Periodontal history, smoking, diabetes and maintenance attendance are reviewed.
- ✓ The restoration’s cleanability, contour, cement and component fit are assessed.
- ✓ Treatment endpoints, reassessment date, maintenance and escalation criteria are written.

Peri-Implantitis: Signs, Assessment and Treatment: eight practical answers
What is peri-implantitis?
It is inflammation around a dental implant accompanied by progressive loss of supporting bone beyond expected initial remodelling.
Is peri-implant mucositis the same thing?
No. Mucositis is soft-tissue inflammation without the progressive bone loss that defines peri-implantitis, although it still needs management.
What are common peri-implantitis symptoms?
Bleeding, swelling, discharge, bad taste, recession and increasing cleaning difficulty can occur. Pain may be absent.
Does a moving dental implant mean peri-implantitis?
A truly mobile fixture is serious, but a loose crown or screw can feel similar. Obtain prompt assessment to identify which component moves.
Can peri-implantitis be treated without surgery?
Initial non-surgical care and risk control are important. Persistent or advanced disease may require surgical treatment; suitability depends on the defect and implant.
Do antibiotics cure peri-implantitis?
Antibiotics alone do not remove biofilm, correct design problems or restore cleanability. Any use must be clinically justified within a broader plan.
Must an implant with peri-implantitis be removed?
Not always. Disease extent, implant stability and position, defect, cleanability, response and patient factors determine prognosis.
How can recurrence be reduced?
Maintain effective daily cleaning, risk-based professional care, periodontal stability and prompt review of bleeding or technical changes.
