Infection does not show up on x-ray?

User Level:
Patient
Posted by: KiteGame  (2 years ago)

I had a root canal done on my lower right first molar ten years ago. For the past month, I have been having an off and on pain in the tooth. The dentist said nothing wrong showed on the x-ray. Since the pain continued, he referred me to an Endodontist.

The Endodontist also took x-ray and said there could be an infection in there. He went in and cleaned it up. The pain did not stop so I went back to the Endodontist. He said the tooth should be extracted now because of a possible hidden infection, which is causing the pain. Is it possible that an infection does not show up in the x-ray sometimes? Should I have this tooth pulled or get a second opinion? Any advice? Thanks so much.

Hello,
X ray is two dimensional (like x and y on a graph).So you can,t say surely what is in the tooth. Past few yrs ago there was a concept that first molar has only three root canals but recent studies say that there r more than three canals.There fore if there any minor canal left it may cause pain .... also check the other causes pls....

Infections don't show up on x-rays until bone is destroyed. Hard to say what is going on. May be a cracked root. You could elect to have the root canal redone, but the success rate drops to about 80% when they are redone. Usually, I don't redo root canals unless there is something very obvious causing failure, like a short fill.

Spotting an infection on an x-ray is tricky unless it affects an opaque structure like your tooth or bone which can be readily identified on an x-ray. Anyway, I'm not sure what your endodontist means by 'hidden infection'. I wish he could be more specific and spell it out instead of throwing the word 'infection' around rather loosely.

In any case, I'm thinking you'd do better to get a second opinion and get to the root of this problem. Good luck!
