1. What causes an endodontically treated tooth to need additional treatment?

A tooth that already has endodontic treatment sometimes need additional treatment due to residual bacteria within the treated canals; additional canals or lateral canals not treated initially; recurrent decay; and tooth fractures.


2. If root canal is performed, won' t the tooth be dead?

A root canal treated tooth is basically "dead" because it has been devitalized by the removal of nerve tissue within the tooth.


3. Will the tooth darken after treatment?

Yes, the tooth does tend to darken a bit after treatment. The amount of darkening is different in each case.


4. Will the tooth crack or fracture?

The tooth does run the risk of cracking or fracturing due to either the condition of the tooth that warranted a root canal or as a result of devitalizing the tooth as a result of treatment. The risk is also dependent on location and function of the tooth that has been treated...and how it may be involved in function of the mouth in the near future.


5. Can a root canal treated tooth be used as an anchor for a bridge?

A root canal treated tooth can be used as an anchor for a bridge if it is appropriate to be used in that application. It is dependent on the location of the bridge; amount of stress it will take; and adequate amount of tooth structure for mechanical retention. If a root canal treated tooth is to be used as an achor, it needs to be adequately evaluated, and any risks and alternatives should be discussed with the patient.


6. Is it normal for the tooth to hurt after Root Canal Treatment?

Occasionally, there is some discomfort after root canal treatment. It is generally due to some temporary inflammation that may be the result of the procedure. Often an adjustment of the tooth or medication is used to counteract any possible discomfort.
