Infection under a root canal...

[kdp81]

I had a root canal in my upper molar about 2 years ago - I just went in to my dentist for a cleaning and because I had been having soreness in the area of the root canal. The X-ray revealed that I have a rather large infection (spread to the sinuses) under the root canal. She says I should have the RC redone, possibly even a bridge or implant - Unfortunately, I don't have insurance so this is not my favorite diagnosis. She put me on an antibiotic with the hope that the infection will clear up. Is that a realistic goal? Also, how does this happen, an infection under the RC? Was the first one improperly done? Any thoughts would be greatly appreciated.

Dear kdp81:
      Root canal treatment is not always 100% successful. The periapical lesion is due to infection. You probably need to see an endodontist to redo rc or periapical surgery.Or, extraction of the infected tooth is alternative option.Good luck.

I had the same thing happen to me & I had to have the root canal re-done.
