If you have previously undergone root canal therapy, you expect the treated tooth to remain healthy and free from infection. However, in some cases, a tooth may not heal as expected or may become reinfected months or even years after the initial procedure.

Why Would a Root Canal Fail?

Several factors can lead to the need for root canal retreatment.

• If the original root canal procedure did not fully clean or seal all of the tooth’s canals, bacteria may remain and cause reinfection.
• Additionally, untreated or hidden canals, cracks in the tooth or breakdown of the crown or filling over time can allow bacteria to re-enter.
• In some cases, a new infection may develop due to a failed restoration or additional trauma to the tooth.

Regardless of the cause, it is important to seek treatment as soon as possible to prevent further damage.

What Happens During Root Canal Retreatment?

Root canal retreatment follows a similar process to the initial procedure, but with added steps to ensure all infection is properly addressed. The tooth is reopened and the previous filling materials are removed to expose the root canals. Our experienced dentists will carefully examine the tooth for any hidden or untreated canals and thoroughly clean out any remaining infection. Once the tooth is disinfected and reshaped, new filling material is placed and the tooth is sealed with a temporary filling. After the healing process is complete, a new crown or permanent restoration is placed to protect the tooth from further issues.
