What is tetanus toxoid vaccine? Tetanus is a serious disease caused by bacteria. Tetanus (lockjaw) causes painful tightening of the muscles, usually all over the body. It can lead to locking of the jaw so the victim cannot open his mouth or swallow. Tetanus leads to death in about 1 out of 10 cases.

Pain in the joint of the jaw accompanied by the inability to open the jaw very far without pain is a frequent sign of a condition called TMJ (temporomandibular joint disorder). This condition is not necessarily serious, but it can become serious if it's not treated.
