Root canal retreatment

Root Canal Treatment - Newmarket dentists by Woo Dental

There is a possibility that a tooth that has received root canal therapy will not heal properly. Consequently, the tooth will begin to decay and hurt in the coming weeks or months. Root canal retreatment is the process of re-crowning the tooth and cleaning the root canals. 

There are several reasons why root canal retreatments are necessary. 

  • Leaking filling material from the cracked crown.
  • New decay tooth
  • Broken tooth
  • Delayed placement of dental restorations. 
  • An injury occurred to the tooth

During the procedure, the dentist in Newmarket will administer local anesthesia. Using a rubber dam, your dentist will isolate the affected tooth to protect it from saliva and bacteria. The duration of the process will depend on the level of inflammation present in the affected tooth. 

In a root canal retreatment, your dentist will first check the inner tooth. They will remove any placed crown, filling material, or any obstructions that block the root canals using a handpiece. In reshaping the root canals, your dentist will make use of tiny instruments. Moreover, to make sure they are clean, they will perform an X-ray of the rootsThe spaces are sealed with gutta-percha after your dentist cleaned the channel. Gutta-percha is a type of sealant that prevents bacterial infections in the canals.  Lastly, your dentist will apply the temporary crown or filling to the tooth.

If you’re in pain, it can be hard to think about anything else. But if your tooth is infected and needs root canal retreatment, there are some things you should know before deciding on treatment. Your Newmarket dentist will help you understand what the procedure involves. Schedule an appointment for more information.
