If you've been living with persistent jaw pain, ear pain, or headaches, you could have “TMJ” – Temporomandibular Joint Disorder. The temporomandibular joint connects the jaw to the base of the skull is what we use daily to be able to talk, chew, or even yawn. TMJ can often be traced back to an improper bite, misaligned jaw joints, or a traumatic injury to the jaw or face.
