TMJ (Temporomandibular Joint) pain affects the joint that connects your jaw to the skull, located just in front of your ears. It can cause discomfort while speaking, chewing, or even opening and closing your mouth. TMJ pain may result from jaw injury, teeth grinding (bruxism), stress, arthritis, or misalignment of the jaw. If ignored, it can lead to chronic pain and difficulty in daily activities like eating and talking.
