Jaw pain or clicking sounds are hallmark symptoms of temporomandibular joint disorder (TMJD). This disorder affects the temporomandibular joint, which connects the jaw to the skull, and is often characterized by discomfort or pain in this area. Patients frequently report a sensation of their jaw "locking" or making clicking or popping noises when they move it, which indicates dysfunction of the joint mechanics. This symptom arises due to issues such as misalignment, arthritis, or muscle tension associated with the joint.

The other symptoms mentioned, while they may be related to TMJD, are not as definitive. Headaches can also occur, often as a secondary effect of jaw tension, but they are not exclusive to TMJD. Neck stiffness can arise from muscle strain associated with the disorder but does not specifically identify TMJD. Ear ringing (tinnitus) may occur in some individuals with TMJD due to the proximity of the jaw joint to the ear, but it is not a primary symptom. Therefore, the presence of jaw pain or clicking is the most direct sign indicating TMJD.
