Short Answer
It can be related when neck stiffness repeats with jaw pain, headache, or clenching.
How to think about it
The jaw and neck often influence each other through posture and muscle tension. Jaw-area muscle tension can stiffen neck muscles, and poor neck posture can increase jaw joint load.
