Bruxism is unconscious teeth grinding or clenching during sleep, and most people who do it have no idea until a partner mentions the sound or a dentist spots the wear on their teeth. Stress is commonly linked to it, and it also overlaps with sleep disorders like sleep apnea, which is part of why it’s worth understanding rather than treating as a purely dental issue.
Who This Is For
This is for you if you wake up with jaw soreness, headaches, or worn/sensitive teeth, or if a partner has mentioned hearing you grind your teeth at night.
Quick Fix / Summary
- Sleep bruxism is largely involuntary, you can’t consciously stop it mid-episode
- Stress and anxiety are commonly linked to it
- It’s also linked to sleep apnea, so persistent grinding is worth mentioning alongside snoring or breathing symptoms
- A dentist-fitted mouthguard is a common way to protect your teeth while you address the cause
- Managing stress and cutting evening caffeine/alcohol may be worth trying, though evidence is limited
- Treatment focuses on protecting your teeth and addressing contributing factors, and a mouth guard may not stop the grinding itself
Why This Happens
Sleep bruxism is considered multifactorial, several things can contribute at once. Stress and anxiety are commonly linked to it, and Mayo Clinic says sleep bruxism appears to be linked to sleep disturbances. Mayo also lists tobacco, caffeine, alcohol, recreational drugs, family history, certain antidepressant and ADHD medications, and conditions such as sleep apnea and GERD as risk factors or associations.
If you already deal with jaw pain when you wake up, bruxism can be one possible cause, and that article covers the symptom, this one covers the cause and how to address it directly.
Other Contributing Factors
- Tobacco, caffeine and alcohol, which Mayo Clinic lists among the risk factors for bruxism (these are associations, not proven causes)
- Certain medications, particularly some antidepressants
- Sleep disorders, including sleep apnea and fragmented sleep generally
- A misaligned bite, in a smaller subset of cases
How to Fix It
1. Get a Dentist-Fitted Mouthguard
Mayo Clinic lists splints and mouth guards, which keep the top and bottom teeth separated during sleep, as a treatment. They can help prevent more tooth damage and relieve jaw pain, but they may not stop the grinding itself.
2. Address Stress Directly
Since stress is commonly linked to bruxism, Mayo Clinic lists stress-reduction approaches such as meditation, yoga and exercise, and behavioral therapy such as jaw relaxation exercises and biofeedback. A wind-down routine may also help, though how much it reduces grinding varies from person to person.
3. Cut Back on Caffeine and Alcohol, Especially in the Evening
Mayo Clinic lists tobacco, caffeine, alcohol and recreational drugs among the factors that can raise the risk of bruxism. That shows a link rather than proof that cutting back will stop the grinding. Cutting back on evening alcohol and caffeine is a low-cost change some people try for a couple of weeks to see whether it makes a difference.
4. Rule Out Sleep Apnea If You Also Snore or Feel Tired
If grinding shows up alongside loud snoring, gasping, or persistent daytime exhaustion, it’s worth reading about sleep apnea symptoms and when to see a doctor, treating the underlying airway issue may help, although it is not guaranteed to reduce grinding.
5. Ask About Medication If It’s Severe
Mayo Clinic lists muscle relaxants, Botox injections and anti-anxiety medicines among possible treatments. These are decisions for a dentist or doctor to make with you, not something to self-treat, and they are not first steps. Do not stop or change a medication you already take without checking with your prescriber.
Practical Tips That Actually Help
- If your jaw is sore each morning → ask your dentist about a nightguard at your next visit
- If evenings are stressful → build in a short wind-down routine before bed
- If you drink coffee or alcohol in the evening → try cutting it for two weeks and compare
- If it comes with snoring or exhaustion → treat the possible sleep apnea connection as a priority, not an afterthought
- Mention new or worsening grinding to your dentist, they can spot wear patterns you can’t see yourself
Common Mistakes to Avoid
- Treating it as purely a dental problem, a mouthguard protects your teeth but doesn’t address why you’re grinding
- Ignoring it because it doesn’t hurt yet, dental wear accumulates silently over years
- Overlooking a possible sleep apnea connection, especially if snoring or daytime exhaustion are also present
- Expecting a permanent fix, bruxism is managed, not cured; the goal is reducing frequency and protecting your teeth

When to See a Doctor
Mayo Clinic advises seeing a dentist if you have symptoms of grinding or jaw concerns. Make an appointment if you wake with jaw pain or headaches, notice worn, chipped or sensitive teeth, or a partner hears grinding. See a doctor as well if grinding comes with loud snoring, gasping or heavy daytime sleepiness, since sleep apnea can be involved, or if it began after starting a new medication. If a child is grinding their teeth, mention it to their dentist or pediatrician. For causes and what to do, see why a child grinds their teeth at night.
Key Takeaways
- Sleep bruxism is largely involuntary and commonly linked to stress
- It’s linked to sleep apnea and fragmented sleep, not just dental anatomy
- A dentist-fitted mouthguard protects your teeth while you address the underlying cause
- Managing stress and cutting evening caffeine/alcohol are low-cost changes some people try, though evidence is limited
