The temporomandibular joint (or TMJ for short) is what is commonly referred to as the jaw. There is one TMJ on each side of our face just in front of our ear and it connects the jaw bone to the skull. Since the joint on each side is connected to the jaw bone they need to function together in unison to allow normal jaw movement when we are talking, eating, yawning etc. It is when they are not functioning together well that you might need the help of your osteopath to correct this.
