Endodontic Retreatment

Endodontic Retreatment in Richmond


Teeth that have had root canal treatment can last a lifetime with proper care. But sometimes, a tooth that has been treated doesn't heal properly or develops new problems months or even years after treatment. In these cases, an additional procedure may be able to support healing and save your tooth. If you have pain or discomfort in a previously treated tooth, talk to us about retreatment.

First, we will discuss your options. If you choose retreatment, we will reopen your tooth to gain access to the root canal filling material. In many cases, complex restorative materials (crown, post and core material) must be disassembled and removed to permit access to the root canals.

After removing the gutta percha canal filling, we can clean the canals and carefully examine the inside of your tooth using a dental operating microscope, looking for any additional canals or unusual anatomy that requires treatment. We will then disinfect, fill and seal them and place a temporary filling in the tooth. If the canals are unusually narrow or blocked, we may recommend endodontic surgery. This surgery involves making an incision to allow the other end of the root to be sealed.

After your retreatment is complete, you will be referred back to your usual dentist to have a new crown or other restoration placed on the tooth to protect and restore it to its full function.

FAQs


  • Why do I need another endodontic procedure?

    As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons, or a new problem can jeopardise a successfully-treated tooth:

    • Narrow or curved canals were not treated during the initial procedure

    • Complicated canal anatomy went undetected in the first procedure

    • The placement of the crown or other restoration was delayed following the endodontic treatment

    • The restoration did not prevent salivary contamination to the inside of the tooth

    • New decay can expose the root canal filling material to bacteria, causing a new infection in the tooth

    • A loose, cracked or broken crown or filling can expose the tooth to new infection

    • A tooth sustains a fracture

  • Is retreatment the best choice for me?

    Whenever possible, it is best to save your natural tooth. Retreated teeth can function well for years, even for a lifetime. Advances in technology are constantly changing the way root canal treatment is performed, so we may use new techniques that were not available when you had your first procedure. We may be able to resolve your problem with retreatment but, as with any dental or medical procedure, there are no guarantees. We will discuss your options and the chances of success before beginning retreatment.

  • What are the alternatives to retreatment?

    If nonsurgical retreatment is not an option, then endodontic surgery should be considered. This surgery involves making an incision to allow access to the tip of the root. Endodontic surgery may also be recommended in conjunction with retreatment or as an alternative. We will discuss your options and recommend appropriate treatment.
