Tetanus (from Ancient Greek τέτανος 'tension, stretched, rigid'), also known as lockjaw, is a bacterial infection caused by Clostridium tetani and characterized by muscle spasms. In the most common type, the spasms begin in the jaw and then progress to the rest of the body. Each spasm usually lasts for a few minutes.
Trismus is defined as painful restriction in opening the mouth due to a muscle spasm, [5] however it can also refer to limited mouth opening of any cause. [6] Another definition of trismus is simply a limitation of movement. [4] Historically and commonly, the term lockjaw was sometimes used as a synonym for both trismus [2] and tetanus. [7]

The blockage of the neurotransmitters γ-aminobutyric acid (GABA) and glycine is the direct cause of the physiological effects that TeNT induces. GABA inhibits motor neurons, so by blocking GABA, tetanus toxin causes violent spastic paralysis. [18]
A common scenario where a newly placed dental restoration (e.g. a crown or a filling) is incorrectly contoured, and creates a premature contact in the bite. This may localize all the force of the bite onto one tooth, and cause inflammation of the periodontal ligament and reversible increase in tooth mobility. The tooth may become tender to bite on.
The spores which cause tetanus are present everywhere, so the only prevention is immunization. Three properly spaced doses of tetanus toxoid vaccine are recommended for women of childbearing age, either before or during pregnancy; this will protect their future babies from neonatal tetanus after delivery.
