Endodontic Retreatment

Endodontic retreatment is a follow-up procedure performed when a previously treated tooth (that has had a root canal) fails to heal properly or becomes reinfected. Though root canal treatments have a high success rate, in some cases, symptoms return months or even years later due to issues such as hidden canals, untreated anatomy, new decay, or damaged restorations. Retreatment involves reopening the tooth, cleaning and reshaping the canals, and sealing them again to preserve the natural tooth and eliminate infection. This procedure is typically performed by an endodontist (a root canal specialist).
Endodontic Retreatment is a dental procedure that involves reopening a previously treated tooth to clean, disinfect, and reseal the root canal system due to persistent or recurrent infection, incomplete healing, or new damage.

It's typically recommended when:

• The tooth didn’t heal properly after the first root canal.
• Pain, swelling, or infection has returned.
• New decay or cracks expose the root canal filling.
• A crown or filling failed and allowed bacteria in.
