Experiencing upper jaw, facial and ear pain on one side of face. Dental exam was fine a month ago. If not teeth what are possible causes? Tmj?

Contact DDS. If the dentist reviewed your radiographs and did a clinical examination, was TMJ addressed? If TMJ symptoms are relevant the dentist may treat you by making a nightguard that would separate your teeth, to lessen grinding if evident. Otherwise, you may be referred to your MD for an evaluation.
