jaw stiffness
Rigid mouth hinge
Jaw stiffness is reduced mobility or tightness in the jaw, making it difficult to open the mouth fully or chew comfortably.
It can result from teeth grinding, tension, injury, or conditions like temporomandibular joint disorder (TMJ).
I woke up with jaw stiffness after clenching my teeth all night.
