TMJ is the source of much pain in the head and neck. A punch to the jaw, or
opened too wide under anaesthetic to surgically remove those nasty but not so wise teeth! Even a whiplash can can cause TMJ ear pain by injuring the jaw joints, stressing the sensitive and highly complex disc within the joint, and its ligaments and muscles.
Thinking perhaps you shoud see your regular dentist or an Orthodontist.
JMHO as I am not an expert on TMJ.
