What’s The Difference Between TMJ and TMD?

The terms TMJ and TMD are very similar, so it’s unsurprising that people get them confused. However, while they both relate to a single disorder, they are actually different things. So, what makes them different?

 

TMJ stands for Temporomandibular Joint

 

The temporomandibular joint can be found on either side of the face, just in front of the ears. Like other joints, its purpose is to connect two different bones together. In the case of the temporomandibular joint, this refers to the skull and the lower mandible/jaw. As with any joint, when the TMJ functions optimally, it operates smoothly, without pain or stiffness. However, when people suffer from problems with the joint, it generally causes unpleasant and debilitating symptoms, and they are said to have TMD.

 

TMD stands for Temporomandibular Disorder

 

Temporomandibular disorder is a condition that affects the movement of the jaw and usually results from issues affecting the temporomandibular joint. Exactly what causes TMD can vary, but some of the most common contributors are said to be:

 

  • Teeth grinding. This is usually a subconscious or unconscious behavior that is better known as bruxism
     

  • An uneven bite (the way that your teeth come together when your jaw is closed)
     

  • Trauma to the head/face
     

  • Premature wear and tear of the joint, such as is seen in patients with conditions like arthritis
     

  • Stress, causes the patient to clench/grind their teeth

 

Signs of Temporomandibular Disorder

 

There is a range of symptoms associated with temporomandibular disorder. You may suffer from one or two symptoms or a combination of all of them. They include:

 

  • Pain in/around your jaw, ear, and temple
     

  • Clicking/popping/grinding noises when you move your jaw
     

  • Difficulty opening your mouth fully
     

  • Headaches radiating from the temples
     

  • Lockjaw when you open your mouth wide, such as when yawning
     

  • Pain that gets worse when chewing
     

  • Pain that keeps you awake at night

 

If you are experiencing any of these symptoms, we recommend that you may an appointment with your dentist to explain them. They will be able to confirm a diagnosis of TMD and talk to you about the available treatments.

 

Treatments for TMD

 

There are also a variety of different potential treatments for TMD, but which you may be offered is likely to depend on what your dentist believes is the cause of your condition. Pain medications are often prescribed, although these are designed to help manage your discomfort and will not get to the root cause of your TMD. It’s crucial to address the cause as well the symptoms of your condition. For example, if your TMD is believed to be caused by stress/grinding your teeth due to stress, you may be recommended to try some relaxation techniques to reduce your stress levels, medications to help you to cope better, and to relax your muscles and even sleep therapy. If your TMD is thought to be because of an issue with your bite, you may be referred for orthodontic treatment to correct it.
