A disorder affecting the jaw joint and muscles that control jaw movement, which may cause pain or limited motion.
Medical records that document your measured maximum unassisted vertical jaw opening in millimeters are central to any rating. Examination findings from a dentist, oral surgeon, or other treating provider showing precise measurements carry direct weight. For the higher ratings within each opening range, a physician must record or verify that you are required to follow a texture-modified diet; a physician's documentation of that dietary restriction — and which level applies, such as full liquid, puree, soft, or semisolid — is necessary to support elevation based on diet.
Diagnostic imaging such as X-rays, CT scans, or MRI studies of the jaw joint can help establish the underlying condition and severity. If your jaw movement is also limited side to side, records measuring lateral excursion in millimeters are relevant. Statements from you or your family describing how jaw pain or limited opening affects eating, speaking, and daily activities can help show the practical impact of your symptoms, particularly when paired with physician-documented dietary restrictions.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
