TMJ and TMD are two initialisms that seem the same because they both have temporomandibular joints in them. It is important to know their differences. That way, you can understand that these groups of letters do not mean the same thing. Below are the differences between TMJ and TMD.
The temporomandibular joint (TMJ) has the important job of connecting the lower jaw to the skull. Each side of the jaw has a jaw joint. It is a little in front of the ears. Keeping this joint healthy is crucial to maintaining a good quality of life. A TMJ that can move without issue can help a person eat and speak with comfort.
The TMJ is a tiny, delicate joint that allows the mouth to open and close. It is a sliding and hinge joint. It is a small joint, yet it is used all the time. That is why it is easy to become irritated or even damaged. Eating and speaking is possible because of the TMJ.
A temporomandibular joint disorder (TMD) is a disorder of the TMJ. Some people also call it TMJD. Research shows that there are about 30 TMDs. All these disorders cause the loss of function in the jaw joint. Each one also causes significant pain. Here are the different classes of TMD:
A visit to the general dentist can detect a problem with this joint. The provider will test the jaw’s range of motion. Pressing lightly around and on the jaw and the jaw joints can test for pain. Ordering a dental X-ray can show a problem in the TMJ. Magnetic resonance imaging (MRI) or cone beam computed tomography (CBCT) can also detect any issue with the jaw and jaw joint.
TMD impacts or damages the jaw joint’s function. It can develop because of arthritis, infection, or overuse. Visiting a general dentist can determine the disorder. The patient can manifest the following TMD symptoms:
The general dentist can recommend some ways to treat mild TMD. Some home remedies can help, including eating soft foods and wearing a nightguard at night. Applying hot and cold compresses can also provide relief. Relaxation and stretching exercises can tone the muscles in and around the joint. The following are interventions for severe TMD cases.
Radio wave therapy uses radio waves. It creates a low-level stimulation to increase blood circulation in the TMJ. Transcutaneous electrical nerve stimulation (TENS) uses a low-level electrical current. It focuses the current on the affected site to relax the facial and jaw muscles.
Braces can correct dental alignment. Studies show that straightened teeth can relieve the tension in the TMJ. Muscle relaxant injections reduce inflammation, while trigger-point injections relieve pain in facial muscles.
