White Bump

I posted last month about haveing a white bump. I did go to the denist and the tooth was dead so I had a root canal my first and hopefullly my last. The white bump is still there. I had the last part of the root canal done on Friday. I told the denist about and he kept an eye out for another root that he may have missed but each e-ray he took everthing looked fine.

The white bump was not there yesturday but is there this morning. Nothing hurts it is still a itttle swollen on the gums from Friday.

I am going back this Friday to get ready for the crown to put on. I will let him know that it keeps coming and going.

Any ideas?
