What causes lock jaw?

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.

Disc dislocation: A limitation in the ability to move the lower jaw suggests the dislocation of the disc in the jaw joint. When it has moved from its normal position, the jaw cannot move as well. It can occur on one or both sides. It may be associated with pain, but not necessarily. Non-surgical treatment is focused on stabilizing jaw position so the disc can return to its normal position and remain there.

You mean "lockjaw"?: Good that you separated the two words because the one above relates to tetanus, in which there is muscular rigidity of a host of areas due to paralysis of inhibitory neurons by the toxin produced by clostridium tetani.

See a dentist: A pathological condition in which the mouth is held shut by sustained spasm of the masseter (jaw) muscle, often observed in cases of tetanus. It can also be an anatomical problem where the lower jaw comes forward out of its socket.

See oral surgeon.: True "lockjaw" is from tetanus bacteria entering your body: Spasms and stiffness in your jaw muscles, stiffness of your neck muscles, difficulty swallowing, stiffness of your abdominal muscles. I'm assuming you mean you jaw stuck. Can either be do jaw out of socket or problem with disk in jaw joint. In any event, see an oral surgeon to help you with diagnosis and treatment.

Lockjaw: Most common cause of lockjaw (trismus) is inflammation of soft tissue around impacted third molar tooth (lower wisdom teeth). Other causes can be inflammation of muscles of mastication (chewing) after removal of wisdom teeth, peritonsillar abscess (around inflamed tonsils), tmj, or rarely result of use of stimulants to treat adhd.

Classically, lockjaw: Is a term for tetanus but it can be used for disease of the TMJ joint of the jaw.

Tmj: Many things can cause the jaw to lock such as disk problems in the jaw joint, arthritis, fracture of the joint, jaw muscle issues, multiple surgeries on the joint and pathology/growth in the joints. See a dentist for an evaluation.
