Your : Your dentist filed down your tooth to take it out of occlusion, in this way it would not be hitting the opposite tooth, which would cause you pain. The filing down of the tooth did not cause the abscess... The fracture which allowed food and bacteria under the gumline did. What was discussed with your dentist? Is the tooth restorable, or does it need to be extracted? Did he/she give you another appointment to extract it, or did they refer you to an oral surgeon? Were you given antibiotics for your infection? Only your dentist knows for sure what the prognosis is of this particular tooth. He may be planning to remove the fractured piece and restore the rest of the tooth with a crown, or he may feel the tooth is unrestorable and needs to be extracted. These are things that should be discussed with your dentist. ...Read more

What happens if i pull the thread from a root canal out (that is over 3 years old)?

Re-infection: I'm assuming you mean the little orangish colored "thread"...That is the material that seals off the tooth from bacterial leakage. If you've removed it there is a pretty good chance that you will get another infection on that tooth. Anytime the root canal filling material is exposed for more than 24 hours, it's recommended to have the tooth retreated. See you dentist. ...Read more

How does a 3 year old root canal become infected?

Leakage: If you have a defective restoration (filling) or crown, bacteria can seep in and create a new bacterial infection. If this happens, the root canal will need to be retreated. Another possibility is that the root is fractured and in that case, the tooth would need to be extracted and replaced with either an implant or bridge. ...Read more
