I have an underbite and left jaw pain had all wisdoms teeth taken out what could cause the pain? the teeth were taken out years ago

Changes in bite: Sounds like a lot of oral issues. It is likely your bite changed significantly after the surgery and extractions. This can cause pain over time, as can a kind of arthritis called TMJ syndrome. However, even years later, decay, infection or other things can happen in the jaw. It is time to see your dentist or oral surgeon.

TMJ: That sounds like TMJ problems developed from change in your bite following wisdom teeth extractions. See your dentist for night guards or possible ortho treatment..

Malocclusion: If teeth and jaws do not meet properly, do not function properly, untoward stress is placed on the jaw joints. Think how your hips would feel if you had 1 lag 10% bigger than it should be when compared to the other. Your malocclusion may have caused Temporomandibular Joint Dysfunction. Please see a qualified Orthodontic Specialist for evaluation.
