Jaw clicking popping, occasionally teeth don't align and painful. Pain travels lower angle of jaw into chin. Sharp pain throughout day. TMJ disorder?

Absolutely. See your Dentist for symptomatic relief. If you have a malocclusion Orthodontic treatment may be in order.
Possibly. The symptoms you describe are indicative of a TMJ disorder, but it can also be related to your occlusion, since your teeth don't appear to interdigitate correctly. Have a local orthodontist take a look... it is possible that once your malocclusion is corrected, your symptoms will disappear.
Yes. Definitely a TMJ disorder. See TMJ expert for advice. Any dentist can be a TMJ expert with the proper training and experience. Most commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask your MD, your dentist and your dental society for referrals.
