Root Canal Re-Treatment

With proper care, most teeth that have had endodontic (root canal) treatment can last as long as other natural teeth. In some cases, however, a tooth that has received endodontic treatment fails to heal. Occasionally, the tooth becomes painful or diseased months or even years after successful treatment.

Why do I need retreatment?

As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial treatment for a variety of reasons:

1. Narrow or curved canals were not treated during the initial procedure.
2. Complicated canal anatomy went undetected in the first procedure.
3. The placement of the crown or other restoration was delayed following the endodontic treatment.
4. The restoration did not prevent salivary contamination to the inside of the tooth.
5. In other cases, a new problem can jeopardize a tooth that was successfully treated.

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 a new infection. A tooth sustains a fracture. Re treatment is performed in two visits and involves the following:

1. Dr. Yousif will examine the tooth, take x-rays and discuss your treatment options.
2. If you decided to go for re-treatment, local anesthetic will be administrated to numb the tooth. After the tooth is numb Dr Yousif 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 the access to the root canals.
3. After removing the canal filling, then he clean the canals and carefully examine the inside of your tooth using a microscope, searching for any additional canals or unusual anatomy that requires treatment.
4. After cleaning the canals, he will fill and seal the canals and place a permanent filling in the tooth.
5. A new crown or other restoration might be needed to place in the tooth to protect and restore it to full function.
6. If the canals are unusually blocked or narrow, Dr Yousif might recommend you to see a specialist, or if you agree the tooth might need to be extracted, he will go in deep details from which option is good for you.

We will discuss with you the exact type of restoration that you will need.
