the locking of jaws is usually due to an abnormality in the articular eminence (part of the jaw joint where the lower jaw rotates). If this part of the bone is not prominant enough, the lower jaw slides over it causing the jaw to "lock". See a maxillofacial specialist, have an x-ray of the joint taken and see if this is indeed the case. If the problem is not severe it can be left as is and you will have to learn to unlock it (ask the specialist to show you how). If it is severe, you may need surgery.
