Gloss & Floss Answers · Bite, Jaw & Teeth Grinding
Why does my jaw hurt in the morning?
Direct answer
Morning jaw pain is often linked to night-time clenching or grinding, jaw muscle overuse, temporomandibular disorder, sleep position, stress or bite overload. It can feel like stiffness, tired chewing muscles, pain near the ears or headache around the temples. If it repeats, worsens or is combined with tooth wear, clicking, locking or headaches, it should be assessed.
Why jaw pain can appear after sleep
During sleep, some people clench or grind without being aware of it. The chewing muscles can work for long periods, leading to morning soreness or stiffness.
Jaw pain can also involve the temporomandibular joints, bite forces, muscle tension, stress or sleep-related factors.
