Pls see attached xrays. The first xray was from the first RCT - it was taken 2 months after filling metapex (metapex was still filled inside). I still had a lot of pain but that first dentist was doing nothing about it and said it's just a wound and wanted to seal it. Then I went to a different dentist (an endodontist) who yesterday checked with a microscope and said he found no fracture/extra canal/perforation, and that the pain must be due to the fact that the lingual canal (the longest one) was not filled all the way to the apex). So he reopened the canals and instrumented them to reach the apex. I had great pain during the process so he gave me a shot of local anesthesia. Aftre he was done, he then inserted the files and took the xray. The second xray is the one he took. I was horrified to see the files extending way way beyond the apex. Were those files inserted into the bone or is that the empty sinus space or what? Is that why I was having so much pain during his treatment? Will I get any long term damage from this? Any advice on what should be done now? He said he irrigated the canals but has not filled any medicine inside the canals (just cotton, i think he said?) and put a temp filling and has told me to come back on March 8 to irrigate the canals again. He realized he has overextended but tried to justify it saying that will drain out any infection. i doubt it as the overextension is so much. It's paining today quite a lot. Pls advise if I will get any long term damage from this? Pls advise on what should be done now.
