Jaw Pain or Soreness
Pain in the jaw — at rest, during chewing, or when opening wide — is the most common TMD presentation. It may be localized to the joint area in front of the ear, or radiate into the temple, cheek, or neck. Pain that has persisted for more than a few weeks warrants assessment.
Clicking, Popping, or Locking
Sounds during jaw movement — clicks, pops, or grinding sensations — often indicate displacement of the articular disc within the joint. Occasional clicking without pain is often benign; clicking accompanied by pain, or jaw locking (difficulty fully opening or closing), requires evaluation.
Headaches & Facial Pain
Tension-type headaches, temple pain, and facial soreness are frequently misattributed to migraines or sinus issues when the actual source is jaw muscle tension or joint dysfunction. Patients with frequent morning headaches often have a bruxism or TMD component.
Limited Mouth Opening
Difficulty opening the mouth fully — or pain at the endpoint of opening — often indicates disc displacement, muscle spasm, or arthritic joint changes. Normal mouth opening is approximately 40 to 50 mm; restriction below 35 mm typically warrants clinical assessment.
