Good evening don’t know if you could assist... \n 2016 cracked tooth on #3 left side of molar - then root canalled tooth and crown (Jan 2017). \n\n Year later pain started in near tooth (sinus pressure) went to dentist November 2018 - got antibiotics for one week. Sinus pressure went away - then went to oral surgeon - said root canal tooth looked fine, and said he needed my dentist to confirm tooth is bad. Said x-rays of root canal look fine. So went to my own dentist and also a second opinion (my doctor referred me) - both said suspected crack tooth and they recommend extraction and implant. \n\n I then went to my root canal specialist who said all was fine with the root canal - but for me to take allergy medicine, and brush left gum area hard to deal with issue there. He only examined mouth, and used a regular X-ray. He said if does not resolve to extract.\n\n I then saw my regular doctor he saw no no sinus blockage. \n\n Symptoms now: when eat or drink feel as if travels to end of tooth - pain fluctuates each day. Feel pressure on tooth area dull pain. Tooth hurts on the left side - pain coming from there. No pain in jaw area. \n\n I then contacted the surgeon’s office with the recommendations of the two dentists...and he said that I still needed to go to TMJ doctor for an evaluation because he felt my jaw on right was tight and he thinks that might be causing tooth pain. When I saw the TMJ specialist (who works in the same practice) he said that I did have tightness in jaw. Sinus is also fine. \n\nHowever, when he was scanning the 3D he also saw a small dark shadow beneath the root on the 3D and he said that might indicate a crack (when I saw the surgeon he did not see this) ... so now for 2 weeks he wants to try TMD treatment to see if that helps. \n\nIf that does not help...then what? I have been in agony for a month...how can TMD help a cracked tooth? \n\n Question: is my option to remove the crown? And do I get a second opinion from another surgeon? \n Also why did the surgeon not consider the two independent dentist evaluations if he only was going to consider only his co-worker evaluation? Any information would be helpful! Thank you!
