Root Canal Question?

I had a root canal and a crown put on about 2 years ago. The tooth is in great shape now and nothing hurts or anything like that. It was in the back on the bottom. The next last tooth. Recently I have had this white bump pop up on my jaw right below where the root canal was done. It looks like there is something trying to poke through that little bump. It almost looks like a end of a toothpick or something. I didn't know if anyone has ever had this before from a previous root canal. I thought it might be something to do with those pins they put in when before they install the crown. I don't know. It doesn't hurt or anything but I was just a little concerned. I called my dentist and he said that sometimes a bump will form to let the tooth drain more from where the canal was done. Any ideas?

Root Canal Question?
Possibly there is another canal in the tooth that has to be treated. An endodontist(root canal specialist) may be able to help. I have seen this happen as long as 10 years after the root canal was originally done.
Reply:Did he say it was an abcess? If so did he give you antibiotics for it?
Reply:if you've had a root removed pieces of it can turn up ages later and come out through your gum like splinters- not scary. Wonder if it could be something like that?


If it hurts rub on clove oil- antiseptic and mildly anesthetic.
Reply:Possible that root canal had relapsed or the tooth has another canal which was untreated,probably unnoticed at the time you had youre root canal.Go to your dentist and have it checked.Have it xray.So your dentist could see if there is another canal or infection on the apex of the teeth.You're not feeling any pain on the tooth,because it has the drainage on the side.A repeat of the root canal procedure is done or apicoectomy.
