Causes of Sore Jaw Joint

| June 20, 2012

A sore jaw joint is usually the result of a physical trauma or an injury. The jaw joint, generally known as the temporomandibular joint, can be a relatively delicate joint, unlike additional joints from the body system. This is certainly one of the many logic behind why temporomandibular joint disorders have become a lot more common everyday. It is also possible for that jaw to simply get dislocated resulting from trauma. Also, due to its proximity towards the ear, there can be spread of infection in the ear to your jaw joint. Hence, there is many conditions that could result to a sore jaw joint.

Causes of Sore Jaw Joint

Trauma and Accidents

The most frequent reason for an aching jaw joint is trauma and accidents. Each time a person has an accident, due to the position of the lower jaw it can easily experience fracture when the person falls with the face first. This can dislocate the jaw, which often causes severe sore jaw joint pain. Also, for people that brawls and fist fights, a blow sideways of your face can potentially dislocate the bottom jaw, that may cause jaw pain specifically in the joint and also a sore jaw bone.


Osteoarthritis is the degenerative disease on the jaw joint. This is usually a condition that is considered with occurs to old people. The temporomandibular joint consists of the articulation of your temporal bone as well as mandible. There’s an articular disc that is present between these bones. With aging, there’s degeneration on the disc and degeneration from the articulating surfaces on the bones. Leading to grinding and rubbing in the articulating surfaces from the bone against one, which ends up in pain and jaw pain when opening mouth.


Dental malocclusion means the misalignment of teeth. Any time a person has malocclusion, it affects the entire facial region. Every time a person suddenly loses his molars, resulting from any sort of accident or because of caries, then to get one other teeth into normal closing (occluding) positions, the jaw needs to move ahead to shut completely, which could result in jaw pain when chewing. This actually also brings about pain within the jaw bone and joint region, because this is not the traditional closing position from the jaw and also the muscles consciously strain themselves for complete closure in the mouth.

Other Causes

There are several other causes which will result in a sore jaw joint at the same time. One common type of a sore jaw joint on one side is undoubtedly an ear infection. If a person developes an ear infection, it can simply spread towards temporomandibular joint and result in inflammation and infection in the joint. Other conditions which could create a sore jaw joint are stress, very stiff jaw muscles (named myofascial pain syndrome), excessive clenching of teeth, etc.
