There could be numerous causes for your discomfort. You could have problems with your TMJ(tempro-mandibular joint) from clenching or grinding habits. Your denture may need adjusting, it coud be referred from your ear, it could also be referred from your lower jaw(if you have dentition there) You will need to consult a dentist to be able to properly diagnose the problem.
