Temporal-mandibular joint dysfunction is more commonly known as TMJ. TMJ can be caused by grinding /clenching of the teeth, injury to the joint or head and neck muscles, arthritis, and stress that causes you to tighten your jaw muscles.
TMJ can be very painful and could have the following symptoms but the condition is not limited to just these symptoms.
Soreness in the area
Clicking or popping of the jaw when moving the mouth
Although surgery may be needed to repair the Temporal-mandibular joint, treatment for this condition can also include adjusting the bite, replacing missing teeth, laser therapy, and night guards. Each TMJ case is different, by having a proper exam and x-rays you and your dentist will find the appropriate treatment.
