Tapping pain, sensitivity on RCT tooth.

Had root canal and crown on#46. No cavities or infection. Have constant burning pain in lower jaw under ear and side of the neck since May month. Dentist suspect there might be a fracture and want me to extract it. I went back to Endodontist and he couldn't see any fracture in microscope. Told me to do Rct and crown. Dentist did cbct scan and suspect fracture from it. Endo didn't take any cbct. Only x-rays taken. I went back to dentist as same symptoms after permanent crown. Dentist tapped on that crown and it hurts. What does it Indicate? He gave me bite paper to check bites. It hurts to bite on the bite paper up and down, front and back. It gives some sore pain and tenderness. I am not chewing food on that side at all. Using opposite side. I am chewing on that tooth only during bite test and it gives sore dull pain and tender. Do I need to extract this tooth? Does tapping pain indicates extraction? My dentist want me to come back next week for extraction. He is not sure though.
