Sleep-Related Bruxism
Repeated grinding or clenching of the teeth during sleep, a common sleep-related movement disorder recognized for its association with jaw pain, headaches, and tooth damage, and, in some patients, with obstructive sleep apnea and certain medications.
In short
Sleep-related bruxism is repeated grinding or clenching of the teeth during sleep, common enough that most people experience it occasionally, but a genuine clinical concern when it's frequent and causes jaw pain, morning headaches, or visible tooth wear. It's associated with stress, certain medications, and, in a meaningful number of patients, obstructive sleep apnea, since arousals from breathing events can trigger the jaw muscle activity behind grinding. Diagnosis usually starts with a dental exam and a bed partner's report of grinding sounds; a sleep study is added when obstructive sleep apnea is suspected as a contributor. Management centers on a custom dental mouth guard to protect the teeth, treating obstructive sleep apnea when present, and addressing stress.
Sleep-Related Bruxism at a Glance
What It Is
Repeated grinding or clenching of the teeth during sleep, ranging from occasional and harmless to frequent enough to cause real dental damage, jaw pain, and headaches.
Common Associations
Stress and anxiety, certain medications including some antidepressants, and obstructive sleep apnea, since breathing-related arousals can trigger jaw muscle activity.
How It Is Diagnosed
A dental exam showing tooth wear, a history from the patient or a bed partner who has heard grinding, and, when obstructive sleep apnea is suspected, a sleep study.
How It Is Managed
A custom-fitted dental mouth guard to protect the teeth, treating obstructive sleep apnea if present, and addressing stress or a contributing medication.
Key Takeaways
- Sleep-related bruxism, repeated grinding or clenching of the teeth during sleep, is common in a mild, occasional form, and becomes a genuine clinical concern when it's frequent enough to cause jaw pain, morning headaches, or visible tooth damage.
- A genuine, recognized association exists between sleep-related bruxism and obstructive sleep apnea, since arousals following breathing events can trigger the jaw muscle activity behind grinding.
- Diagnosis usually relies on a dental exam and a bed partner's report rather than a sleep study; a sleep study is added specifically when OSA is suspected as a contributor.
- A custom-fitted dental mouth guard protects the teeth effectively, though it doesn't necessarily stop the underlying grinding behavior itself.
- Stress, certain antidepressant medications, and heavy caffeine, alcohol, tobacco, or stimulant use are each recognized contributors, so an evaluation looks beyond stress alone when grinding is frequent or damaging.
Symptoms
What You or a Bed Partner May Notice
- Grinding or clenching sounds during sleep, most often first noticed by a bed partner
- Jaw pain or soreness, particularly on waking
- Morning headaches, often felt at the temples or jaw
- Worn, flattened, or chipped teeth noticed at a dental checkup
- Tooth sensitivity to hot, cold, or pressure
- Jaw tightness or fatigue that eases as the day goes on
Less Widely Known Features
- Tension extending into the face, neck, or shoulders
- Fragmented sleep from grinding-related arousals, even without conscious awareness of waking
- Overlap with temporomandibular joint (TMJ) symptoms, including jaw clicking or restricted opening
- Some people clench forcefully without audible grinding, so a bed partner may notice nothing even when symptoms are present
Could This Be Sleep-Related Bruxism?
My partner says I grind my teeth at night. Should I do anything about it?
It's worth mentioning to your dentist or physician, especially if you also notice jaw pain, morning headaches, or your dentist has commented on tooth wear. Occasional, mild grinding without symptoms often doesn't need treatment, but frequent grinding with these effects is a reasonable reason to be evaluated.
I wake up with jaw pain and headaches but no one has ever mentioned hearing me grind my teeth. Could this still be bruxism?
Yes. Some people clench forcefully without producing an audible grinding sound, so a bed partner may not notice anything even when symptoms are real. A dental exam looking for tooth wear, combined with your symptom pattern, can still point toward bruxism even without a witnessed grinding sound.
Could my teeth grinding actually be connected to sleep apnea?
It's a reasonable question, and a genuine, recognized association exists between sleep-related bruxism and obstructive sleep apnea, discussed in more detail below. If you also snore, have witnessed breathing pauses, or feel excessively sleepy during the day, that combination is worth raising specifically with your physician.
Is teeth grinding just a stress thing, or could it be something more?
Stress and anxiety are common, genuinely important contributors, but bruxism isn't explained by stress alone in every case. Certain medications, and, for a meaningful subset of patients, obstructive sleep apnea, can also drive it, which is why an evaluation looks at more than stress alone when grinding is frequent or damaging.
What Causes Sleep-Related Bruxism?
Not a Single Cause
Sleep-related bruxism isn't explained by one factor alone; it's generally understood as arising from a combination of contributors that differ from person to person.
Stress and Anxiety
One of the most consistently identified contributors, thought to increase jaw muscle activity during sleep in susceptible individuals.
Sleep Arousals and Fragmented Sleep
Bruxism episodes tend to cluster around brief arousals from sleep, whatever is causing them, which is part of why treating an underlying cause of fragmented sleep can reduce grinding.
Obstructive Sleep Apnea
A recognized association exists between sleep-related bruxism and obstructive sleep apnea, with grinding sometimes occurring around the brief arousal that follows a breathing event, discussed further below.
Certain Medications
Some antidepressants, particularly certain SSRIs and SNRIs, are associated with new or worsened bruxism in some patients. This is a described association worth mentioning to a prescriber, not a reason to stop a medication independently.
Caffeine, Alcohol, Tobacco, and Recreational Stimulants
Each is associated with an increased likelihood of bruxism in some studies, plausibly related to their effects on arousal and muscle activity during sleep.
Genetic Contribution
A family history of bruxism in some patients suggests a genetic component, though no single defined mechanism explains every case.
Risk Factors
- Significant stress or anxietyOne of the most commonly identified contributors
- Untreated obstructive sleep apneaA recognized association discussed in its own section below, though the exact relationship is still being studied
- Certain antidepressant medicationsSome SSRIs and SNRIs are associated with new or worsened bruxism in some patients
- A family history of bruxismSuggests some genetic contribution
- Heavy caffeine, alcohol, tobacco, or recreational stimulant use
- Frequent, fragmented nighttime arousals from any causeBruxism episodes often cluster around brief arousals, whatever triggers them
Why Sleep-Related Bruxism Matters
Dental Damage
Repeated grinding can wear down, flatten, chip, or loosen teeth over time, sometimes requiring restorative dental work if left unaddressed.
Jaw Pain and TMJ Symptoms
Chronic jaw soreness, fatigue, clicking, or restricted opening can develop alongside or independent of dental damage.
Headaches
Tension-type headaches, often centered at the temples or jaw, are a common consequence, particularly noticeable on waking.
Sleep Disruption
Frequent grinding can fragment sleep for the person experiencing it and, through the sound itself, for a bed partner as well.
A Possible Clue to Undiagnosed OSA
Because of the recognized association between the two, new or worsening bruxism can be a reason to specifically ask about, and screen for, obstructive sleep apnea rather than treating it as an isolated dental issue.
When Should I Talk to a Sleep Specialist?
- A bed partner reports frequent grinding or clenching sounds during sleep
- Morning jaw pain, soreness, or headaches, particularly if recurring
- A dentist notices new or worsening tooth wear, chipping, or flattening
- Jaw clicking, popping, or restricted opening
- Grinding or jaw symptoms alongside snoring, witnessed breathing pauses, or daytime sleepiness
- New or worsened grinding after starting a new medication
What Is Sleep-Related Bruxism?
A Common Sleep-Related Movement Disorder
Sleep-related bruxism is repeated grinding or clenching of the teeth during sleep. It’s classified as a sleep-related movement disorder, one of several categories covered in our broader guide to parasomnias and related sleep behaviors.
A Wide Range of Severity
Occasional, mild grinding is genuinely common and often doesn’t need treatment on its own. What turns bruxism into a real clinical concern is frequency and consequence: jaw pain, morning headaches, visible tooth wear, or a bed partner’s sleep being disrupted by the sound of it.
Sleep Bruxism vs. Awake Bruxism
Bruxism isn’t limited to sleep; some people also clench or grind while awake, often during periods of concentration or stress. The two forms are distinct enough to be worth telling apart.
Sleep Bruxism vs. Awake Bruxism
| Dimension | Sleep Bruxism | Awake Bruxism |
|---|---|---|
| Timing | During sleep, often clustered around brief arousals | During waking hours, often during concentration, stress, or focus |
| Awareness | Largely unaware; often first noticed by a bed partner or a dentist | Often noticed by the person themselves once pointed out |
| Typical Pattern | Rhythmic grinding, sometimes with audible sound | More often sustained clenching without grinding |
| How It Is Usually Recognized | A bed partner's report, or tooth wear found at a dental exam | Self-noticed jaw tension or a dentist's observation |
This page focuses on sleep-related bruxism specifically, since its evaluation and, in particular, its association with obstructive sleep apnea are distinct from daytime clenching.
Recognizing Sleep-Related Bruxism
What a Bed Partner May Hear
Grinding sounds during sleep are often the first sign anyone notices, though some people clench forcefully without an audible sound.
What You May Feel on Waking
Jaw pain or soreness, tightness, and morning headaches, often centered at the temples or jaw, that tend to ease as the day goes on.
What a Dentist May Find
Worn, flattened, or chipped teeth and increased tooth sensitivity are common findings at a routine dental checkup, sometimes before a patient has connected them to nighttime grinding.
The Obstructive Sleep Apnea Association
Sleep-related bruxism and obstructive sleep apnea are separate conditions, but a genuine, recognized association exists between the two, and it’s worth understanding rather than treating bruxism only as a dental issue.
What the Association Looks Like
In patients with OSA, brief arousals that follow breathing pauses appear to trigger jaw muscle activity in some cases, which is one proposed mechanism behind why bruxism and OSA occur together more often than would be expected by chance in some studies. Not everyone with bruxism has OSA, and not everyone with OSA grinds their teeth; the relationship is a recognized association, still being actively studied, rather than a fixed rule.
What It Means for Evaluation
Because of this association, new or worsening bruxism, particularly alongside snoring, witnessed breathing pauses, or daytime sleepiness, is a reasonable reason to specifically ask about OSA rather than assume grinding is unrelated to breathing during sleep. When OSA is confirmed and treated, some patients see their bruxism improve as well, though a dental mouth guard is often still used to protect the teeth regardless.
How Sleep-Related Bruxism Is Diagnosed
The Evaluation Pathway
- 01History and Bed Partner ReportA physician or dentist reviews symptoms, frequency, and any grinding sounds a bed partner has noticed.
- 02Dental ExamA dentist looks for characteristic tooth wear, flattening, chipping, or other signs consistent with grinding, which can confirm bruxism even without a witnessed sound.
- 03Screening for Contributing FactorsStress, medications, and substance use are reviewed as possible contributors.
- 04Screening for Obstructive Sleep ApneaSnoring, witnessed breathing pauses, and daytime sleepiness are specifically asked about, given the recognized association.
- 05Sleep Study, When OSA Is SuspectedAn in-lab or home sleep study is added when OSA or another sleep disorder is suspected as a contributor, confirming or ruling it out.
- 06Personalized Management PlanA dental mouth guard, treatment of any confirmed OSA, and attention to stress or a contributing medication are planned around the individual findings.
Most sleep-related bruxism is diagnosed through history and a dental exam alone, without needing a sleep study; a sleep study is added specifically when there’s reason to suspect a coexisting sleep disorder like OSA, not as a routine step for every patient with grinding.
Management
Management of sleep-related bruxism generally combines protecting the teeth with addressing whatever is contributing to the grinding itself.
Dental Mouth Guards
A custom-fitted occlusal splint, made by a dentist, is the most direct way to protect teeth from the physical force of grinding, and is appropriate for most patients with bothersome or damaging bruxism.
Treating Underlying OSA
When obstructive sleep apnea is confirmed, treating it, most often with CPAP, can reduce the arousal-related jaw activity that contributes to grinding for some patients.
Stress Management
Relaxation techniques and addressing daytime stress can meaningfully help patients whose bruxism appears linked to stress or anxiety.
Reviewing Medications and Substances
A physician may discuss a contributing medication with your prescriber, or address heavy caffeine, alcohol, tobacco, or stimulant use when one of these appears to be a factor.
A dental mouth guard is often recommended regardless of what else is contributing, since it protects the teeth directly while other contributing factors, like OSA or stress, are addressed on their own timeline.

The clinical information on this page applies to patients everywhere; what differs locally is simply where that evaluation and follow-up care happens.
Patient Questions
What is sleep-related bruxism?
It's repeated grinding or clenching of the teeth during sleep. Occasional, mild grinding is common and often not medically significant, but frequent grinding that causes jaw pain, headaches, or visible tooth damage is a genuine clinical concern worth evaluating.
What are the most common symptoms of sleep bruxism?
Grinding sounds a bed partner notices, jaw pain or soreness on waking, morning headaches often centered at the temples or jaw, and worn, flattened, or chipped teeth found at a dental checkup are the most recognized signs. Some people clench forcefully without any audible grinding, so a dental exam can pick up cases a bed partner never hears.
Is teeth grinding always caused by stress?
No. Stress and anxiety are common, genuinely important contributors, but bruxism can also be associated with certain medications, particularly some antidepressants, and, in a meaningful number of patients, with obstructive sleep apnea. A physician or dentist evaluation looks at the full picture rather than assuming stress explains every case.
Is there really a connection between teeth grinding and sleep apnea?
Yes, a real and recognized association exists between sleep-related bruxism and obstructive sleep apnea. Grinding episodes appear to cluster around the brief arousals that follow breathing events in some patients with OSA, and treating the underlying OSA can reduce bruxism for some of those patients. Not everyone with bruxism has OSA, and not everyone with OSA grinds their teeth, but the association is worth asking about, particularly if you also snore or have witnessed breathing pauses.
How is sleep-related bruxism diagnosed?
Diagnosis usually starts with a dental exam looking for characteristic tooth wear, combined with a history from the patient and, often, a bed partner's report of grinding sounds. A sleep study is added when obstructive sleep apnea or another sleep disorder is suspected as a contributor, since confirming or ruling that out changes the treatment plan.
Do I need a sleep study just to diagnose teeth grinding?
Not usually for bruxism alone. A sleep study becomes relevant specifically when there's reason to suspect obstructive sleep apnea or another sleep disorder is contributing, such as snoring, witnessed breathing pauses, or daytime sleepiness alongside the grinding, rather than as a routine step for every case of bruxism.
What is a night guard, and does it actually stop the grinding?
A night guard, or occlusal splint, is a custom-fitted dental device worn during sleep. It protects the teeth from the physical force of grinding and clenching very effectively, but it doesn't necessarily stop the underlying muscle activity itself; it's a protective measure alongside addressing contributing factors, not a cure on its own.
Can treating my sleep apnea help my teeth grinding?
For some patients, yes. When obstructive sleep apnea is a meaningful contributor, treating it, most often with CPAP, can reduce the arousal-related jaw activity that drives grinding. This isn't guaranteed for every patient, and a dental mouth guard is often still recommended to protect the teeth in the meantime.
Can medications cause teeth grinding?
Certain medications, notably some SSRIs and SNRIs used for depression or anxiety, are associated with new or worsened bruxism in some patients. This is a described association worth mentioning to your prescriber, not a reason to stop or change a medication on your own; that decision belongs with the prescribing clinician.
When should I see a doctor or dentist about teeth grinding?
Reasonable prompts include a bed partner reporting frequent grinding, morning jaw pain or headaches, a dentist noting new tooth wear, jaw clicking or restricted opening, or grinding occurring alongside snoring, witnessed breathing pauses, or daytime sleepiness. A dental or physician evaluation can clarify what's contributing and build an appropriate plan.
