Types of TMJ Disorders

TMJ or temporomandibular joint, as it is more commonly known, is one of the most complex joints in the human body. Here, our Sault Ste. Marie dentists describe the three most common types of disorders that can affect the TMJ joint.

What exactly is TMJ Disorder?

The TMJ is the joint that connects the jaw to the temporal bones of the skull (located just below your temple and in front of your ear). You use this hinge joint every time you move your jaw to breathe, talk, or eat.

Temporomandibular joint disorders occur when there is a problem with the facial muscles and the jaw. You might start to feel pain in the area and the joint can eventually become immobile if the disorder is severe enough.

There are three main types of TMJ disorders that a patient may experience:

The Common Types of TMJ Disorder

Muscle Disorders

This pain is known as myofascial pain and involves discomfort or pain in all the muscles that control your jaw’s function. You may feel pain in your shoulders, neck, and jaw muscles.

Joint Derangement Disorders

To make the opening and closing of the jaw easy and smooth, there is a small, soft disc placed between the condyle and the temporal bone. This disc also absorbs shocks to the jaw joint during its movements.

With joint derangement disorders, the inner workings of the jaw are unbalanced or disrupted due to a damaged bone or dislocation of a disc. The displacement of the disc leads to internal derangement of the temporomandibular joint. For the moment, no surgery can treat this problem. 

Joint Degenerative Disorders

This disorder is more commonly known as osteoarthritis. The round ends of the two bones in a joint are held together by cartilage. This allows the bones to glide effortlessly over each other. It also absorbs shocks during movements.

A joint degenerative disorder occurs when cartilage wears away or breaks away. Along with being unable to move the jaw, the patient may also experience pain and swelling to varying degrees.

Typical Symptoms Associated With TMJ Disorder

No matter which type of TMJ Disorder you have, you’ll likely feel pain in your face, jaw, and around your ears when you open your mouth to talk or eat.

Other symptoms can include:

  • Clicking, popping, or grinding sounds when you open your jaw
  • Additional pain that moves down into your neck and shoulders
  • Headaches, pain in your temples or dizziness
  • Facial bruising or swelling
  • Problems opening, closing or clenching your jaw

When it might be time to see a dentist

While you should schedule a visit with your dentist at the first signs of TMJ disorder, you should definitely book an appointment if you have tried home remedies such as gently massaging your jaw and neck muscles, avoiding stress, chewing gum, and over-the-counter non-steroidal anti-inflammatory drugs with no relief.

If you are experiencing the symptoms of TMJ disorder then your dentist will review your dental history, complete a thorough examination of your teeth and facial structure, and take X-rays to study before diagnosing you with TMJ Disorder. The possible treatments for TMJ conditions may include:

  • Dental splints
  • TMJ Therapy
  • Oral Surgery (for severe cases)
  • Physical Therapy
  • Prescription medications

With your dentist’s help, your TMJ Disorder can often be managed with a combination of dental care and home remedies.
