Jaw Pain On One Side

When you experience jaw pain on one side, it can be severely debilitating. The pain can be so strong that it will prevent you from doing simple things such as eating or talking to people. The causes that trigger the jaw pain on one side are diverse. They can be classified into two categories: primary and secondary. The primary causes are the ones affecting the area directly. On the other hand, the secondary causes refer to a medical condition that comes from other part of the body and affects the jaw indirectly.

In general, most of the jaw pains are caused by injury or dental problems. The secondary causes need to be diagnosed by a specialist.


The jaw pain can appear as a consequence of several causes. These causes can be related to to physical injury, nerve problems, or blood vessel problems.

The most common cause that are responsible for the jaw pain is temporomandibular joint disorder (TMJ). 12% of the planet’s population is affected by TMJ. However, just 5% will talk to a specialist and ask for help. Women of childbearing age are most commonly affected by TMJ.

TMJ collectively describes disorders of the temporomandibular joints, and the muscles responsible for jaw movement. These muscles are known as the masticatory muscles.

The most common causes for jaw pain on one side are the following:

  • Teeth grinding, clenching, or opening the mouth too wide: Most often, teeth grinding and clenching is experienced during sleep. This behavior can lead to tooth damage and jaw pain. This behavior can appear whenever you feel an increased emotional stress.
  • Osteomyelitis – appears asĀ  a consequence of an infection in the body. It affects the bones and associated tissues.
  • Arthritis – several conditions such as osteoarthritis and osteoarthrosis can lead to the surface of bones wearing away.
  • Synovitis or capsulitis: These are conditions in which the lining of the joint or a connecting ligament becomes inflamed.
  • Dental conditions – gum disease, cavities, tooth gaps, damaged teeth, or abscesses.
  • Sinus problems
  • Tension type headaches – typically caused by stress and may lead to facial pain.
  • Neuropathic pain: It is a long-term pain that occurs when nerves become damaged and send pain signals to the brain. This pain can be continuous or occur from time to time.
  • Vascular pain – occurs when the supply of blood to part of the body is disrupted. It is caused by conditions that include giant cell arteritis and carotid artery dissection.
  • Neurovascular pain is caused by conditions that affect both the nerves and the blood vessels, such as migraine and cluster headaches.

The jaw pain can also appear due to lifestyle-related factors, including emotional stress, sleep disturbances, a lack of certain nutrients, or tiredness.

There can be also other conditions that can cause the jaw pain. These are the following: rheumatoid arthritis, hypothyroidism, Lyme disease, multiple sclerosis, lupus, fibromyalgia, and some mental health conditions.


The jaw pain can have the following symptoms:
  • facial pain that worsens when the jaw is used
