There are many potential causes of jaw and ear pain including injury, temporal mandibular joint (TMJ) dysfunction, fluid buildup, toothache, and ear infection. Grinding of the teeth may also lead to pain in both the ear and jaw. Each condition requires separate treatment and the severity of pain may vary based on the underlying problem.

Most causes of jaw and ear pain relate to some type of injury or illness. Blunt trauma to the side of the face can lead to swelling and pain in the ear and jaw region. This may occur during a fall or sports-related accident or in an automobile accident. Treatments vary but may include medication or surgery. Many injuries heal on their own.

Another common cause of jaw and ear pain is toothache. This can include nerve damage pain or problems related to tooth decay, such as cavities or gum disease. Swollen gums may accompany the soreness or a throbbing sensation may be present. A dentist or physician can generally diagnose and treat toothache related pain. Ear infections may also cause pain in the jaw and ears due to a buildup of pus or fluids. Most heal on their own without treatment, but sometimes antibiotics are prescribed.

Grinding of the teeth and TMJ may also lead to jaw and ear pain. This is due to pressure and fluid accumulating around the upper jaw and back of the ear. Mouth guards are generally the first line of defense in both cases. These are used to prevent grinding and clenching of the jaw and sometimes to realign the jaw line properly. In very severe cases surgery may be necessary.

Various conditions may also lead to buildup around the ears and jaw, and this can also lead to pain. This can be due to many factors and it often goes away without treatment. Sometimes it is due to infection, but many times the cause is never discovered.

Anyone suffering from severe jaw and ear pain should contact a doctor for diagnosis. Since there are so many various causes for discomfort, a thorough check up may be needed to determine the cause. Some conditions have additional symptoms and they may affect different parts of the ear and jaw. This can make diagnosis easier. Most conditions which cause jaw and ear pain are treatable and not serious.
