Yet, a tooth that has received treatment may fail to heal or pain may continue to exist. Sometimes, the pain may occur months or years after treatment.

If retreatment is the chosen course, the endodontist will reopen your tooth. Gaining access to the root canal filling material can be more complex than a routine root canal, involving additional steps including the removal of crown, post and core material. Three of them involve performing some type of endodontic retreatment procedure.

In more formal terms, this approach is referred to as orthograde or non-surgical endodontic retreatment. The use of a rubber dam for tooth isolation is mandatory in endodontic treatment for several reasons: It provides an aseptic operating fiel isolating the tooth from oral and salivary contamination. It facilitates the use of the strong medicaments necessary to clean the root canal system.

Root canal treatment has a very high rate of success, but as with other medical or dental procedures, infection or inflammation may persist or recur despite our best efforts. If your tooth failed to heal or develops new problems, you have a second chance. In some cases, however, a tooth that has received endodontic treatment fails to heal or the pain continues. For example, the doctor will assess your tooth, remove the root canal filling material, then thoroughly clean the canals and carefully analyze the inside of 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, the endodontist will discuss your treatment options.

If you and your endodontist choose retreatment , the endodontist will reopen your tooth to gain access to the root canal filling material. Teeth that have had root canal treatment can and do last a lifetime. However, on occasion, the tooth that has been treated fails to heal properly or becomes tender or sensitive months or years after it was treated. This sensitivity can be addressed and resolved without losing the tooth. Consequently, surgical retreatment tended to be associated with higher indirect costs than a nonsurgically approach.

In the final part of the thesis it is argued that retreatment decision making in everyday clinical practice normally should be based on simple principles. Root canal retreatment is a procedure used to clean the canals of a tooth that have already been subject to a root canal. Although most root canals are successful the first time, there are many reasons why a retreatment may be necessary.

But sometimes, a tooth that has been treated doesn't heal properly and can become painful or diseased months or even years after treatment. With proper care, even teeth that have had root canal treatment can last a lifetime. Retreated teeth can function well for years, even for a lifetime. As occasionally happens with any dental or medical procedure, a tooth may not heal as expected after initial endodontic therapy (root canal treatment) for a variety of reasons.

A cracked or loose filling or crown can expose the tooth to new infection. Once retreatment has been selected as a solution to your problem, the doctor will reopen your tooth to gain access to the root canal filling material.
