What is the difference between TMJ and TMD? Really, it’s not much,TMJ TMD unless you happen to be a dentist. You may have heard friends say, “My jaw is killing me and my dentist says I have TMJ.” Actually, the dentist probably said that the problem was TMD.  The difference is simply this – TMJ is the temporomandibular joint. TMD is temporomandibular joint disorder.

You probably don’t care about the terminology – what you care about is the fact that your jaw hurts or you have headaches, toothaches, or pain in your neck or on the sides of your face and it just isn’t going away.

Sometimes even dentists use the terms interchangeably. Terminology doesn’t matter. What does matter is that it hurts, and it needs to be treated. Usually. Sometimes, TMJ (or TMD) will go away on its own, but not often. All right, let’s stop the terminology thing. From here on, just to make it easy, we’re going to say TMD.

So Who Gets TMD?

TMD knows no boundaries. It doesn’t care if you’re male or female, black or white, young or old. That said, TMD most often occurs in women over the age of 40. It can affect either or both sides of your face. It is usually chronic and will not go away without treatment.

What Causes TMD?

TMD can be due to arthritis in the TMJ. It can also be due to head or neck injuries. Anything that causes abnormal movement in the head or neck muscles can cause TMD. Grinding the teeth can also cause TMD and in fact, most of the time people can grind their teeth at night without even realizing they’re doing it.

TMD symptoms can include:TMD

  • Locking jaws
  • Jaw pain
  • Popping, clicking or grating when chewing
  • Dizziness
  • Earaches
  • Toothaches
  • Ringing in ears
  • Neck pain
  • Headaches

From these symptoms, you can tell that TMD can be very hard to diagnose – these symptoms can also indicate other medical problems. That’s why it is so important to get a proper diagnosis.
