A patient has constant pain in their TMJ, regardless of opening or closing. What is causing this?

• A. Anterior disc with reduction
• B. Anterior disc without reduction
• C. Muscle problems
• D. Dislocation

Answer: (D)

Constant TMJ pain that doesn’t change with whether you open or close the jaw points to a structural derangement where the joint is out of its normal position. In a dislocation, the condyle moves forward past the articular eminence and the joint is no longer congruent. That abnormal position irritates the surrounding tissues and keeps the pain present regardless of how you try to move the jaw until the joint is reduced back into place. Other scenarios fit different pain patterns: disc displacement with reduction usually has a click and the jaw can move, with pain tied to movement rather than constant at all positions. Disc displacement without reduction tends to limit opening and pain is related to movement, not a constant across all jaw positions. Muscle-related TMJ pain tends to be activity-dependent or relieved with rest rather than persisting in every position of the jaw.
