Why do I wake up with jaw pain?
Last updated September 3, 2026.
Morning jaw pain usually means you are grinding or clenching in your sleep. The NHS links bruxism most often to stress and anxiety, and also to sleep problems like snoring and sleep apnoea, some medicines for sleep, depression, or anxiety, smoking, and heavy alcohol or caffeine intake. Overnight, your jaw muscles do the work without your awareness, and the bill arrives at sunrise: aching jaw, temple headache, tender teeth. Self-help starts with sleep hygiene, winding down, and cutting late caffeine and alcohol. A dentist can confirm the diagnosis from tooth wear and fit a night guard or splint to protect your teeth while you work on the cause.
What to do
- Ask your partner or family if they hear grinding at night; it confirms the diagnosis.
- Fix the sleep inputs: regular schedule, dark quiet room, no late caffeine or alcohol.
- Ice a sore jaw for 20 to 30 minutes and use paracetamol or ibuprofen on bad mornings.
- See a dentist for a guard if it keeps happening or teeth look worn.
- Mention snoring to your GP; grinding plus snoring plus morning headaches suggests sleep apnoea.
