Endodontic retreatment: $1,200-$1,800
Single implant (surgery + restoration): $3,500-$5,200
Extraction and bone grafting: $800-$1,400

Insurance coverage patterns significantly impact patient decisions. According to the National Association of Dental Plans, 68% of dental insurance plans provide coverage for endodontic retreatment, while only 42% offer implant coverage.

Long-term Financial Considerations

Lifetime treatment costs require careful evaluation:

Retreatment Scenarios:

Initial retreatment success: $1,500 average total cost
Retreatment failure requiring extraction/implant: $5,200 cumulative cost
Crown replacement over 20 years: Additional $2,400

Implant Scenarios:

Initial implant success: $4,350 average total cost
Crown replacement over 20 years: Additional $2,200
Peri-implantitis treatment: Additional $1,800-$3,200

How Should Patient-Specific Factors Guide Decision Making?

Contemporary treatment planning emphasizes individualized risk assessment and patient preferences. The American Academy of Periodontology's 2026 guidelines recommend comprehensive evaluation of multiple patient factors.

Medical History Considerations

Systemic Health Factors:

Diabetes control (HbA1c levels)
Smoking status and cessation timeline
Bisphosphonate therapy history
Immunocompromised status

Age-Related Considerations:

Patients under 25: Retreatment often preferred
Patients over 65: Implant considerations increase
