For the last couple of days I have throbbing in a tooth that I had a root canal and crown put on a few years ago. It's not painful per se, just a throbbing, almost like I can feel my heart beating through my tooth. Weird, huh?

I thought when they do a root canal that the tooth is basically dead and they fill the roots with some sort of packing material. I know this cost me a pretty penny to get done as we have no dental coverage with our health insurance. I'm not going to be very happy if I have to get this done all over again!

I've heard of cases where they only killed 3 roots and there were 4, so yes, some pain could come back. I hope that it's not the case for you.
It could be something else like your bite needs adjusting.

Yes it can. If they didn't get all of the nerve, but more likely because the crown is a foreign surface in the mouth, the gums will always be slightly irritated and more likely to form small pockets that allow decay to creep between the gums & remaining tooth structure where it can get infected. Or they can crack & fracture causing pain.

I hope it's something easy and minor though! Dental work is hella-expensive!

Yes they definately can and I've had to have a tooth extracted because of it! When you go in for a root canal they have you sign a form with a bunch of fine print about what can go wrong. Go to the dentist asap and have it checked. I put mine off way too long....ended up not only losing the tooth but needing a bone graft as well. I need to get an implant now where that tooth was.

I had a root canal go bad after 8 years. It was an upper tooth and I felt this weird lump in my mouth... I put pressure on it... and it was infected(UGH). Dentist had to extract it. I would schedule an appt with your dentist.

You might also consider that the problem is coming from the tooth right next to it. When you have a blob of pain, sometimes it is difficult to differentiate. (Yup, that happened to me.)

Either way, get it checked out sooner rather than later.

Yep! I had one go bad after a YEAR!!!! Luckily they did not recharge to fix it. The crown did not set on properly in the first place. I'm so sorry you are going through this!! It's never fun!

Yep, it sure can...and I'm sitting here after another root canal this morning trying to get the pain to ease up. A previous dentist didn't get all the root out and infection set in.

Yep, I had mine go bad. I was having pain in the tooth off and on. I ended up at the oral surgeon's office getting the tooth pulled and now I have a dental implant. Definitely get it checked out!!

They can go bad and it does happen quite a bit. They are not guaranteed to be permanent. The root canal could be fine and all, but the tooth can develop a crack in it or a number of other things. That can cause the sensitivity. You may end up having to have the tooth extracted. Go see your dentist.

Agreeing with everyone else. I was actually told that he wouldn't be surprised if the tooth he was doing the root canal on started bothering me again. There looks like there was trauma to it, and my the canal was shaped in a way where he couldnt physically remove the entire root without going through my gum into the top of my tooth.

Oh, and I agree with the PP who said it may be the tooth next to it. I have a hard time really pinpoint tooth pains sometimes.

Good luck!
