Root Canal Retreatment Cost
Nonsurgical root canal retreatment commonly costs $1,200-$2,500 before a new filling or crown. Existing filling material, posts, crowns, missed anatomy, and infection make retreatment more complex than first-time care.
Key takeaways
- Retreatment usually costs more than initial therapy.
- Crown access or replacement can add substantial cost.
- Apical surgery is a separate alternative in selected cases.
- Prognosis should be reviewed before investing in another procedure.
Root Canal Retreatment Cost cost comparison
| Option | Typical cost | Planning note |
|---|---|---|
| Nonsurgical retreatment | $1,200-$2,500 | Existing canal material removed |
| Apicoectomy | $1,000-$2,500 | Surgical treatment at root end |
| New crown after access | $1,000-$2,500 | Needed if old crown cannot be retained |

What affects root canal retreatment cost?
Tooth type, posts, separated instruments, calcification, crown access, infection, imaging, and specialist time affect the quote.
Ask for a written treatment plan that identifies every procedure, material, temporary restoration, and follow-up visit. A low advertised fee is useful only when the included services are comparable.
How to compare your options
Retreatment cleans the canals again from above; apical surgery approaches infection through the gum and bone. Extraction may be considered when fracture or poor support limits prognosis.
Compare clinical suitability first, then total cost over the expected lifespan. Monthly payments can make treatment easier to budget, but interest and fees can change the amount repaid.
Insurance, financing, and next steps
Coverage varies and a plan may apply frequency limits or combine retreatment with the year's restorative maximum. Request a pre-treatment estimate.
Confirm the deductible, waiting period, annual maximum, exclusions, and preauthorization requirements directly with the plan. Provider estimates remain subject to the insurer's final claim decision.
Frequently asked questions
How much does root canal retreatment cost?
A typical range is $1,200-$2,500 before restoration.
Why did the first root canal fail?
Persistent bacteria, missed anatomy, leakage, new decay, fracture, or delayed restoration can contribute.
Is retreatment better than an apicoectomy?
The best approach depends on anatomy, prior work, restorability, and the source of infection.
Will insurance pay twice?
It may, but frequency rules, plan limitations, and remaining annual maximum affect payment.
