The temporomandibular joint is the joint of the jaw, which is commonly known as the TMJ. There are two joints, one on either side of the head. Temporomandibular joints are located in front of your ears, where your lower jaw meets the skull. You can feel the joint when you place your fingers in front of your ears on either side of your head, and try to open and close your mouth.

The TMJ enables movement of your jaw when you eat your food, and of course when you talk and sing. It is one of the most commonly used joints in the body.

TMJ disorder is a general term that refers to the pain or discomfort in the temporomandibular joint area. It is a very painful condition, which involves the jaw joint and the muscles surrounding it.

To learn more about the temporomandibular joint disorders, it is necessary to understand the normal anatomy of the TMJ.

Normal Anatomy of TMJ

The temporomandibular joint complex consists of the following structures that work in harmony for the smooth functioning of the joint:

Muscles of Mastication

These are complex groups of muscles that allow your mouth to open and close. When these muscles are relaxed and not under stress, they work in conjunction with the other parts of the TMJ complex.

The Teeth and Occlusion

Occlusion refers to the way the upper and lower teeth come together when you bite. A bad bite may damage the joint, whereas a normal occlusion provides support to the joint.

What Makes up the Temporomandibular Joint?

  • Mandibular condyle: the rounded ends of the mandible (lower jaw).
  • Temporal fossa: the joint socket over which the condyle glides.
  • The articular disc or meniscus: present between the condyle and fossa, and is made up of cartilage-like material. It slides in a forward direction in the socket when you open the mouth.
  • Ligaments: these hold the disc onto the condyle and stabilize the joint.
  • Connective tissue: this holds the disc at the back of the joint and contains blood vessels and nerves. It also surrounds the joint like a capsule.

Types of TMJ Disorders

TMJ disorders are broadly divided into three types:

  1. Myofascial pain: This is the most common form of the disease, and involves discomfort or pain in the muscles of the jaw, neck and shoulder.
  2. Internal derangement of the joint: This type is caused by disease or damage inside the joint itself. It can be a displaced disc, dislocated jaw or a condylar injury.
  3. Degenerative Joint disease: DJD occurs in people suffering from osteoarthritis and rheumatoid arthritis. The joint surfaces wear down, causing pain and grinding noises during movement of the jaw.

Common Causes of TMJ Disorders

Stress: This is the main cause of TMJ pain. Stress leads to habits like clenching and grinding your teeth, which can cause muscle spasm and jaw pain.

Diseases: Certain diseases, like rheumatoid arthritis and osteoarthritis, can cause pain in the joint. In both these conditions, the cartilage is lost and the bone surface erodes away.

Injury to the jaw: Injury can lead to fracture of the condyle and disc displacement.

Oral habits: Oral habits such as bruxism (night grinding of teeth) or clenching lead to muscle spasms.

Bad bite or malocclusion: Malalignment of the teeth and jaws can cause problems in the way your teeth fit and place the masticatory muscles under stress.

Symptoms of TMJ Disorders

You may experience the following symptoms:

  • Dull, aching type of pain in the jaw
  • Headache and dizziness
  • Difficulty in swallowing, biting, opening and closing the mouth

  • Clicking and popping sound opening and closing the mouth
  • Pain in the ears
  • Stiffness in the jaw muscles

Diagnosis of TMJ Disorders

Your dentist will ask you about your symptoms and medical history, and also perform a physical examination.

Physical exam involves:

  • Examining your teeth, jaw joints, facial muscles and head
  • Listening for clicking/popping sound when you open your jaw
  • Palpation of jaw joint, facial muscles and head

Other tests that may be ordered by your dentist:

X-rays: Panoramic dental X-rays can show a wide view of jaws, teeth and roots.

Tomogram: This type of X-ray shows different sections throughout the joint. It is used to diagnose arthritis and injuries.

CT scan: This type of scan uses a computer to make internal pictures of the joint and helps see bony details.

MRI scan: Magnetic and radio waves are used to picture the jaw joint.

At home: You can apply warm compresses over the painful area. Exercise your lower jaw by moving it side to side and trying to open and close your mouth. Try this after you apply a warm compress for 20 minutes.

Medications: Muscle relaxant medicines are prescribed, which help control muscle spasm and pain. Non-Steroidal Anti-inflammatory Drugs (NSAIDs) like aspirin or ibuprofen will reduce pain and swelling. Low-dose antidepressants may also be given for pain modification.

Physical Therapy: Physical Therapy exercises help relax your muscles and improve jaw movements. Physiotherapists use the Transcutaneous Electrical Nerve Stimulation (TENS) unit and ultrasound, which promotes tissue healing and helps relax your muscles.

Diet changes: You should eat a soft diet and eat small amounts of food at each sitting.

Splint therapy: This treatment is suggested to eliminate the effects of clenching or grinding the teeth. A splint is an appliance that fits over the chewing surfaces of your upper and lower teeth.

For those with a temporomandibular joint disorder (TMD), a moveable jaw repositioning appliance can be used to train the jaw to close in the correct position. These are also known as splints and can be worn either on the upper or lower jaw.
