I had a filling on my back molar afterwards experienced extreme pain by ear, ear aches, scalp sensitivity. etc..I posted a question a week or so ago was advised it may be occlusual interference. Went back to the main dentist looked at tooth stated it did not need a root canal it was just a broken tooth big filling , however on the tooth two places up had a large cavity he could not fill it needed a root canal and that should take away all my pain. I told him I felt my bit was off could not bring my teeth together anymore, so he looked back at the big molar with the filling and adjusted the bite, by shaving it down a bit instead of removing the filling. Had a root canal on 6/24.. initial symptom are still there! Should I have the filling removed? Should I see a Neuro Dr? Another Dentist or Endo ???I don't want to return to the office, I feel they just not listening and making things worse! I want to sue them actually, but of course I need another party to verify. PLEASE HELP.. I can't live on Motrin for the rest of my life and my quality of life is bring disrupted
