Greetings ,
From your description, it is Temporomandibular joint dysfunction. It is caused due to the bite alterations done during your full mouth crown rehabilitation procedure.it can be treated Easily 

Hi

The pain you describe and considering the treatment you had done could either be cause by occlusal interferences or nerve damage, is always best to discharge the occlusal interferences or high points of occlusions first before jumping in to performing a more invasive dental procedure such as root canals for example, this are normally performed after several vitality proofs and x-rays that will determine if in fact there is an existing nerve damage problem. My advice is to consult a prosthodontist and an endodontist if these two in the same clinic and they can see you the same day is best.   

Hello, consider know if you don’t have root canal in all those teeth possible it cause sensibility in all your teeth.
