Greetings, I had a root canal done about 2.5 months ago but still feel a low level of discomfort in the tooth when I floss it or wiggle it with my fingers. Should the pain be completely gone or does it sometimes linger for a long time ?

It does sometimes take some time for it to settle, especially if there was a large abscess or infection prior to starting the root canal. Do you have any post treatment x-rays you could share?

Thanks for the reply. There was no abscess/infection at all. The way I found out I needed a root canal was by having a routine set of x-rays done. The xrays showed the #18 molar had decayed in the front part of the tooth. So I tried sticking a fingernail into that front part of the molar and that was the only time I could feel a little discomfort. Will check to see if I can access the post procedure xray...

Took a while to get these. I believe they are "before" and "after" root canal pics...

The root canal looks good. Sometimes the tooth takes a while to settle. I would give it 6 months. If the sensation is still there after that amount of time, other investigations might be needed in order to rule out missed accessory canals or cracks. Try not to wiggle it too much. Every tooth still has ligaments around it,even if the nerve is removed, and excessive wiggling can contribute to inflammation of this ligament, resulting in pain.

Thanks again Dr. M. I came to a similar conclusion last week-just leave the tooth undisturbed. My dentist believes it highly unlikely that the root canal failed but never explained why he thinks that to be true. About a month ago he shaved down the crown because he thought it was too high but that did not help. My endo says to give it more time. My endo did do a high tech/expensive/3D scan before the root canal. The office is unable to email me that scan but wondering if the pain persists, would that scan be helpful in figuring out what the issue is ?
