What Is TMD?

If you experience frequent pain in the jaw area, especially when eating or speaking, you may have TMD. Read on to learn about this disorder, and what your dentist can do to help you treat it.

Wait, Is It TMD or TMJ?

You may have heard of the pain in the jaw area known as TMD. Or maybe you’ve heard it referred to as TMJ. So what’s the difference? TMJ is actually an acronym that represents the temporomandibular joint, the joint directly in front of your ear that connects your lower jaw to your skull. Whereas TMD, or temporomandibular joint disorder/dysfunction, refers to problems with that joint, the jaw, and the muscles that make the jaw work. TMD is thought to have a variety of different causes, including arthritis, injury, clenching, grinding, excessive gum chewing, stress, and anxiety.

Common TMD Symptoms

Most people with TMD will experience pain and sensitivity in the jaw area, sometimes accompanied by swelling. That pain can also travel to the neck and shoulders or cause difficulty when opening the mouth. Patients with TMD may notice that their jaw clicks or locks as they move it, making it hard for the affected individual to bite or chew their food.

Oral Appliance Therapy for TMD

If you think you might have TMD, your best bet in dealing with it is to talk to our expert dentists. We will be able to give you tools to help manage the pain and prevent the issue going forward. One of the most effective ways to address TMD is to engage in oral appliance therapy. Such an appliance, also known as a splint, helps to keep the upper and lower teeth apart so that they don’t touch, which eases the pressure on the temporomandibular joint. Oral appliances are generally worn for the majority of the day, whenever the patient is not eating. Alternatively, we may recommend another form of treatment, like a nightguard or relaxation techniques, to address your TMD and relieve your discomfort.
