What Is Sleep Bruxism?

Sleep bruxism is a sleep-related movement disorder in which the jaw muscles clench or grind the teeth repeatedly during sleep. Many people don’t know they grind their teeth until a dentist notices worn enamel or a bed partner hears the sound. While occasional grinding is common, frequent bruxism can damage teeth, strain the jaw, and signal an underlying sleep disorder.

The Connection Between Bruxism and Sleep Apnea

Research suggests teeth grinding often occurs alongside brief arousals from sleep, including arousals caused by obstructive sleep apnea and upper airway resistance syndrome. When the airway narrows, the jaw may clench or move as the body briefly wakes to restore breathing. That is why a sleep evaluation can be an important part of understanding why you grind your teeth.

Signs and Symptoms of Sleep Bruxism

  • Grinding or clicking sounds during sleep reported by a bed partner
  • Worn, flattened, chipped, or sensitive teeth
  • Jaw pain, tightness, or fatigue in the morning
  • Dull morning headaches near the temples
  • Earache-like pain without an ear infection
  • Unrefreshing sleep, snoring, or daytime fatigue

Risk Factors

  • Stress and anxiety
  • Sleep-disordered breathing such as sleep apnea
  • Alcohol, caffeine, and tobacco use
  • Certain medications, including some antidepressants
  • A family history of bruxism
  • Other sleep disorders, including periodic limb movement disorder and parasomnias

How We Evaluate Teeth Grinding

Your sleep specialist will review your symptoms, sleep habits, and health history and look for signs of a sleep-related breathing disorder. If sleep apnea or another disorder is suspected, an in-lab or home sleep study may be recommended. In-lab studies can also record jaw muscle activity during sleep. We often work alongside your dentist, who can assess tooth wear and provide protective night guards.

Treatment Approaches

  • Treating underlying sleep apnea with CPAP therapy, oral appliance therapy, or Inspire therapy
  • Coordination with your dentist for a custom night guard to protect your teeth
  • Stress management and relaxation techniques before bed
  • Limiting caffeine and alcohol, especially in the evening
  • Reviewing medications that may contribute to grinding

Children can grind their teeth too, sometimes in connection with enlarged tonsils or snoring. Our pediatric sleep team can help evaluate children with these symptoms. Explore all conditions we treat.

Sleep Bruxism FAQs

What causes teeth grinding during sleep?

Sleep bruxism is linked to brief arousals from sleep, stress, sleep-disordered breathing, certain medications, alcohol, caffeine, and genetics.

Is teeth grinding a sign of sleep apnea?

It can be. Grinding often occurs alongside arousals caused by airway narrowing, so a sleep evaluation is worthwhile if you also snore or feel tired during the day.

Will a night guard stop sleep bruxism?

A night guard protects your teeth from damage but does not treat underlying causes such as sleep apnea.

Can treating sleep apnea reduce teeth grinding?

For many patients with sleep-disordered breathing, treating the airway problem can reduce arousals and related grinding.

Do children grind their teeth at night?

Yes. Bruxism is common in children and is sometimes associated with snoring or enlarged tonsils.

Do I need a sleep study for teeth grinding?

Not everyone does, but a sleep study is recommended if your provider suspects sleep apnea or another sleep disorder.
