Limited openingCan limited mouth opening be related to TMJ function?
It can be related, but it should not be assumed. Muscle guarding, joint motion, pain defense, posture, clenching, and sudden change need to be separated.

Do not forceShould I force my mouth open if it does not open well?
It is safer not to force it. Record how far it opens, where pain starts, whether it catches, and whether closing is difficult.

Why it happensWhy does my mouth not open well?
Limited opening can involve chewing-muscle tension, joint catching, pain defense, neck posture, clenching, or grinding. The pattern matters more than a single label.

CatchingWhy does my jaw catch when I open my mouth?
A catching feeling can come from joint movement that is not smooth, disc movement, or protective muscle tension. Opening range, deviation, sound, and muscle tenderness are compared.

Sound then lockingMy jaw clicked before, and now my mouth does not open well. Could it be a disc problem?
It is possible, but clicking followed by limited opening is not always a disc problem. Joint catching and muscle guarding should be separated before deciding next steps.
KO FAQ: FAQ-OBOK-TMJ-OPENLIMIT-003
DeviationMy jaw shifts to one side when I open. Is that a TMJ problem?
It can be related, but mild asymmetry alone does not prove a problem. Pain, clicking, catching, limited opening, and the direction of deviation should be checked together.

ExaminationWhat is checked when mouth opening is limited?
Opening range, pain start point, jaw deviation, clicking or locking moment, chewing-muscle tenderness, imaging history, and bite records may be compared.

Urgent evaluationShould I go to a clinic quickly if my mouth suddenly does not open?
If the change is sudden and severe, follows trauma, includes swelling or fever, makes eating or speaking difficult, or the jaw feels dislocated, prompt evaluation may be needed.
