Several causes: Lock jaw or the inability to open or close the lower jaw can be related to a number of causes. An infection, spasm of the muscles that control the opening and closing of the lower jaw, a broken jaw that did not heal correctly, and problems associated with the meniscus or disc in the TMJ are some possible causes.

TMJ expert: You are likely referring to locking of the jaw related to jaw joint (TMJ) disk displacement and not tetanus related "lockjaw". The locking jaw means there is a serious TMJ problem. See a TMJ expert. Any dentist can be a TMJ expert with the proper training and experience. Commonly, oral surgeons, prosthodontists, and orofacial pain specialists. Ask MD, dentist and your dental society for referrals
