Teeth Grinding at Night: Causes, Morning Signs and What Helps
If you wake with a tight jaw, a dull headache around the temples or teeth that feel sore, you may be grinding them in your sleep. It is common, it often goes with stress, and it is worth a dentist check before the enamel pays for it. Most people do not need anything dramatic: calmer evenings, less late caffeine and alcohol, and sometimes a dentist-fitted night guard.
At a glance
- Night grinding is called bruxism; you often learn about it from a partner who hears it.
- Morning signs: jaw ache, tight temples, sensitive or worn teeth.
- Stress, snoring or sleep apnoea, caffeine, smoking and alcohol are common links.
- Treatment is not always needed; a dentist decides if a guard helps.

Why do I grind my teeth in my sleep?
The NHS says teeth grinding is often related to stress or anxiety. It is also linked to sleep problems such as snoring and sleep apnoea, heavy alcohol or caffeine use, smoking and some medicines. Grinding can occur awake or asleep, and many people clench their jaw in the day without noticing, during traffic, screens or tough conversations. The cause is often a mix rather than one thing.
How do I know if I grind at night?
- You wake with jaw ache, tightness around the temples or a dull headache.
- Your teeth feel sensitive, look flattened or worn, or have small chips.
- A partner, sibling or roommate hears a grinding or clicking sound.
- Your ears ache without an infection, or your sleep feels broken.
These signs can also come from other causes, so the pattern alone is not proof. A dentist can look at wear on the teeth and check the jaw joint.
How to stop grinding teeth at night: simple steps
- Cut caffeine after midday, and avoid alcohol and smoking close to bedtime.
- Build a calm last hour: dim lights, no work messages, a warm shower. If your mind is busy, try the notebook method in cannot sleep because of overthinking.
- Do a few jaw relaxation moves before bed: gently open and close the mouth ten times, then massage the cheek muscles for a minute with your fingertips.
- Avoid chewing gum and very hard or chewy foods when the jaw is sore.
- Keep regular dental check-ups, and ask the dentist to check for wear.
Try this: lips together, teeth apart
Rest the tongue gently on the roof of the mouth with the lips closed and the teeth slightly apart. Set a few phone reminders across the day to check your jaw. Many people clench awake too, and learning the relaxed position by day makes it easier for the jaw to loosen at night. If you find your teeth touching, that is your cue to let the jaw drop. It is a habit trick, not a guaranteed fix.
Do I need a night guard?
Maybe. The NHS notes that treatment is not always needed, but a dentist may suggest a custom-made mouth guard that fits over the upper or lower teeth and protects them from damage. A guard protects teeth, but it does not remove the underlying cause. Avoid random store-bought guards without advice: they can fit badly, shift your bite or hide a problem like sleep apnoea. Ask a dentist first.
Can sleep apnoea cause teeth grinding?
It can be linked. If you also snore loudly, wake gasping or feel tired all day, tell your doctor, because treating the breathing problem matters more than the guard. Another night oddity worth separating out is twitching in the muscles, covered in muscle twitching at night: when to worry.
A realistic evening plan for a busy week
You do not need an elaborate routine. On a tough day, do three small things: stop caffeine early, spend five minutes loosening the jaw and shoulders, and put your phone down fifteen minutes before sleep. If the jaw is sore in the morning, a warm, damp cloth held against the cheek for several minutes can ease the tightness, and a cold pack wrapped in a towel suits an inflamed, tender joint. Keep the pressure gentle, and stop if it hurts more. Soft foods for a day or two, such as khichdi, daal or yoghurt, give the muscles a rest. Track mornings for two weeks; if jaw ache is fading, you are probably heading the right way, and if it is not, a dental visit is the next step rather than another remedy.
Teeth grinding in children
Children also grind, often during growth or around stress, and many grow out of it. Do not try home remedies or give any medicine. If you hear it often or the teeth look worn, book a dental visit.
What happens if I do not treat it?
Over time, grinding can wear down enamel, crack teeth or fillings, and cause lasting jaw pain or headaches. The problem is more about the cost to your teeth and comfort than about danger. For gentle everyday dental habits, see clean between your teeth daily. If your neck is also stiff from your sleeping position, stiff neck after sleeping may help.
Limits and when to see someone
This is general information, not a diagnosis. See a dentist if you have tooth damage or sensitivity, jaw, face or ear pain, or a partner hears grinding, or if your child grinds. See a doctor if stress, anxiety, smoking or alcohol feels out of your control, or if you snore loudly, gasp or feel exhausted. Painkillers for jaw ache should follow the pack or a pharmacist’s advice. Seek urgent help for jaw pain with chest pain, or a jaw that locks open or shut.
Frequently asked questions about night teeth grinding
Why do I grind my teeth in my sleep?
Stress is the most common link, along with caffeine, alcohol, smoking and sleep problems like snoring or apnoea. Often several factors combine.
How to stop grinding teeth at night?
Reduce late caffeine and alcohol, wind down before bed, relax the jaw and see a dentist about a fitted guard. There is no guaranteed quick fix.
Is teeth grinding caused by stress?
Often it is linked to stress or anxiety, but not always. Sleep problems and substances also play a part.
Why does my jaw hurt in the morning?
Overnight grinding or clenching can tire the jaw muscles and leave them sore. Other causes exist, so a dentist should check if it persists.
Do I need a night guard?
Only if a dentist thinks your teeth need protecting. A custom guard is different from a generic one from a shop.
Can sleep apnoea cause teeth grinding?
It can be associated. If you snore loudly or are very sleepy in the day, see a doctor.
Is teeth grinding common in children?
Yes, and it often settles on its own. Mention it to a dentist at the next visit, or sooner if the teeth look worn.
What happens if bruxism is not treated?
Teeth can wear or crack, and jaw pain and headaches can continue. Regular dental checks catch damage early.
