Temporomandibular joint disorders are conditions that cause discomfort and inhibit the proper functioning of the jaw joint and muscles that control jaw movement. Causes In most cases, the cause of TMJ disorders is not evident. However, here is a list of potential causes: External trauma, such as a hard hit to the head or jaw. Tooth grinding or jaw clenching. Poor alignment between top and bottom teeth. Excessive chewing (e.g. gum or fingernails). Overextending the TMJ while eating large things. Degenerative diseases. Symptoms There are various symptoms that could be related to TMJ disorders. Examples of these are the following: Pain in facial, jaw, neck or back muscles. Swelling. Muscle stiffness or limited movement of the jaw. Clicking, popping or grating sounds accompanied by pain when moving the jaw. Teeth not fitting comfortably together. Jaw not opening uniformly or locking. Headache or earache. Difficulty swallowing. Diagnosis There is not always a straightforward way of diagnosing TMJ disorders. Exact causes and symptoms are not clear, and that means the discomfort someone is experimenting could be due to different health issues. Your doctor will take your symptoms and medical history into consideration and then will examine areas of discomfort, including the head, neck, face, and jaw. The doctor might also use x-rays in the analysis of your case. Treatment Reversible Treatments Conservative treatments do not invade the tissues of the face, jaw, or joint, or involve surgery. Reversible treatments do not cause permanent changes in the structure or position of the jaw or teeth. It is advisable that you try these first, before considering more expensive and permanent ones. Muscle and ligament tightness can be helped with jaw stretching and relaxing exercises as advised by your doctor. If the jaw becomes locked, it may be necessary to manipulate the joint back into place under a general anaesthetic. The most common TMJ issues are temporary and do not get worse. Short-term use of pain relievers, such as ibuprofen, may be sufficient. A stabilization splint or a bite guard may provide relief. Stabilization splints should only be used for a short time and should not cause permanent changes in bite. Permanent Treatments There is often debate around the use of permanent methods to treat TMJ disorders. There are no long term studies that show the efficacy of these methods, plus they are extensive and often more expensive than reversible treatments. The bite may be adjusted by polishing teeth, using reconstructive dentistry, or fitting braces. A repositioning splint may be fitted, which over time will permanently change the position of the jaw, ligaments and muscles. There may be an effect on teeth alignment, so more dental work may be needed to adjust the teeth. There is even the option to replace the jaw joint with artificial implants, but it should be considered a last resort. Self-Care In many cases, self-care measures can help alleviate the symptoms of TMJ disorders: Eating soft foods. Applying cold or warm compresses. Avoiding excessive jaw movements (shouting, gum-chewing, and wide yawning, for instance). Practicing gentle jaw stretching and relaxing exercises. Resting the jaw as much as possible.
