Causes Of Trismus

Temporomandibular Joint Disorder

The temporomandibular joint works like a hinge connecting the jaw to an individual's skull. It also makes it possible for an individual to open and close their mouth. Crooked teeth and an incorrect bite, or alignment of teeth, also causes temporomandibular joint disorder, resulting in pain, swelling, and trismus. An individual may have this condition due to trauma, arthritis, genetics and grinding the teeth. Patients with this disorder have pain around their ears, in their jaws, and up and down their necks. A person with temporomandibular joint disorder will also have problems opening and closing their mouth. The muscles around this joint become inflamed or damaged and can cause trismus at that point. Some of these painful muscle symptoms can be managed at home with nonsteroidal anti-inflammatory medications and warm packs applied to the affected areas. But if symptoms worsen or occur more often, medical assistance is required to help relieve jaw pain.
