Root Canal Retreatment

Many patients are referred to Dr Oguntebi in order to have a root canal filling redone. If the dentist has been unable to access the full extent of the tooth or the infection has been resistant to their best efforts then referral to a specialist is necessary.

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:

  • 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.

In other cases, a new problem can jeopardize a tooth that was successfully treated. For example:

  • 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.

What will happen during retreatment?

First, Dr Oguntebi will discuss your treatment options. If you choose retreatment, Dr Oguntebi 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.

The key again is disinfection but with retreatment the original filling material has to be removed and the whole root system investigated to be sure that there are no additional canals, (spaces harboring bacteria), which need to be treated.

After cleaning the canals, Dr Oguntebi will fill and seal the canals and place a temporary filling in the tooth. You will need to return to your dentist as soon as possible to have a new crown or other restoration placed on the tooth to protect and restore it to its full function.

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. Dr Oguntebi will use advanced techniques that were possibly not available when you had your first procedure. As with any dental or medical procedure, there are no guarantees. Dr Oguntebi will discuss your options and the chances of success before beginning retreatment.
