Retreatment & Complex Cases
Root Canal Retreatment
A second chance for teeth where previous root canal treatment has not healed as expected.
What is it?
Retreatment involves carefully removing the previous root filling material, re-examining the canal system for missed anatomy or persistent infection, then re-cleaning and re-sealing the tooth. Many of these cases are referred by general dentists precisely because they are technically demanding.
What does it address?
- Root canal treatment that has not healed
- Recurring pain or swelling in a treated tooth
- Missed canals or incomplete previous treatment
- Teeth considered unsalvageable elsewhere
Who may benefit?
Patients with a previously root-treated tooth showing continuing symptoms or radiographic signs of infection, where the tooth remains restorable.

Frequently asked questions
Why did my first root canal fail?+
Common reasons include complex or missed canal anatomy, persistent bacteria or leakage of the restoration.
Is retreatment better than extraction?+
Where the tooth is restorable, retaining your natural tooth is usually preferable. Both options are discussed honestly.
Can every failed case be saved?+
No. Some teeth cannot be saved, and this is explained clearly after assessment.
