I would try these maneuvers to figure out if pain is a referred pain due to TMJ or due to the tooth problem itself. If you move your jaw without biting your teeth and you have the same pain, the pain you have had with biting is indeed a referred pain from your TMJ. Vice versa, try to move or knock the molars with a small plier, if you elicit the same pain, molar problem is likely the culprit.

An occlusal discrepancy may be causing your issue. TMJ pain can possibly be referred. Either tooth may have a fracture or a subclinical infection that is not showing up on your radiographs. Have an endodontist evaluate those two teeth, and have your bite equilibrated by your dentist.

2 most probable causes are infection and inflammation, or both. "High" restoration cause inflammation, as can joints inflammation. As x-rays alone are 2 dimensional, teeth may require 3-D CBCT and evaluation by a specialist Endodontist. Fractures or unfilled auxiliary canals can represent areas of infection/inflammation.
