Hi Amee,

No, an infection does not always show up on an xray as it is only a two dimensional picture. It will show up on a scan, depending on the type of scan, if it has proliferated beyond the tooth. Unfortunately, dentists are still learning how to read these scans because there are changes that occur in the surrounding bone when infection is present that they often do not recognize.

The issue with root canaled teeth is simple... they are ALL infected. There are no exceptions. It is just a matter of time before the infection spreads beyond the tooth.
