What does this mean?
What sets this symptom apart is not how severe it is but when it happens. The pain is there when you wake, eases over the first hour or two, and fades as the day goes on. That pattern says the process producing the pain has been at work overnight; it is a different story from tension that builds up during the day.
During night-time clenching and grinding, the chewing muscles stay contracted for hours. The ache that follows gathers in the temples and at the angle of the jaw; you wake with a jaw that feels tired and stiff, and the first yawn is hard work. Flattened tooth surfaces and fillings and crowns that keep breaking are findings that support this story.
Where breathing is disturbed again and again during sleep, the pain is more often dull and spread out. It comes with loud snoring, waking with a bone-dry mouth, getting up in the night to pass urine, and daytime sleepiness despite enough hours in bed. Both pictures can be present in the same person, which is why a morning headache is looked into by taking the jaw findings and the sleep pattern together.
The cause of a morning headache is often looked for in sleep: muscles loaded through the night, breathing that is disturbed, or both. The headings below are the conditions most often mentioned alongside this symptom.
Likely causes
What helps at home?
- For a week, note the time you wake, how long the pain lasts and whether your jaw feels stiff; this record is the most useful thing you can bring to an examination.
- Ask whoever sleeps next to you to watch for snoring, pauses in breathing or the sound of grinding; this is the one part you cannot notice on your own.
- Go over evening alcohol and any sedatives you take before bed with your doctor; both can change how you breathe at night and how your muscles relax.
- Do not use shop-bought mouthguards that you mould yourself on your own initiative; an appliance that does not fit can affect your bite and your jaw joint for the worse.
- The headache is severe enough to wake you from sleep
- You have been told that your breathing stops during sleep, or you wake up gasping for air
- Daytime sleepiness is a struggle for you while driving or at work
- The pain comes with nausea, vomiting, changes in your vision, or weakness in an arm or leg
- The pain is on the same side every morning and has been getting worse over weeks
Frequently asked questions
- Is my morning headache caused by grinding my teeth at night?
- Night-time clenching is one of the common causes of morning pain, but it is not the only one. The details that suggest clenching are these: a jaw that feels tired and stiff when you wake, pain gathering in the temple and at the angle of the jaw, and pain that passes in the first few hours. An examination looks for tooth wear and muscle tenderness; if the findings suggest a sleep-related cause, a sleep study may be requested.
- I snore. Could that have anything to do with my morning headache?
- It could. Disturbed breathing during sleep changes the balance of oxygen and carbon dioxide in your blood, and that can be felt as morning pain. Whether snoring is simple snoring or a picture that includes pauses in breathing can only be sorted out with a sleep study. A dentist can see the findings inside your mouth and make that referral; any decision about an oral appliance is taken after the study.
- Can I take a painkiller every day for morning pain?
- The occasional painkiller may get you through the day. Taking one every single morning, however, can turn into a separate reason the headache keeps going. If you need them on more than a few days a week, looking into whether the pain starts at night is a better route than raising the dose.
