What is Sleep Bruxism?
Sleep bruxism—commonly known as teeth grinding during sleep—is a prevalent condition affecting approximately 8% of the UK population. While occasional grinding may not cause harm, persistent bruxism can lead to significant dental and health issues.
Sleep bruxism is an involuntary behaviour characterised by the grinding or clenching of teeth during sleep. It typically occurs in the lighter stages of sleep and is often unconscious. While the exact cause remains unclear, several factors are believed to contribute:
- Stress and anxiety: Emotional tension is a significant trigger for bruxism.
- Sleep disorders: Conditions like sleep apnoea and sleep talking are associated with increased bruxism episodes.
- Medications: Certain drugs, including antoidepressants such as SSRIs (Selective Serotonin Reuptake Inhibitors) and antipsychotics, have been linked to bruxism.
- Lifestyle factors: High caffeine intake, smoking, and alcohol consumption can exacerbate the condition.
- Dental issues: Misaligned teeth or jaw abnormalities may contribute to bruxism.
- Genetics: A family history of bruxism can increase the likelihood of developing the condition.
Recognising the symptoms
Common signs of sleep bruxism include:
- Worn or flattened teeth
- Jaw pain or stiffness
- Headaches, particularly upon waking
- Disrupted sleep due to grinding sounds
- Earache or facial pain
Individuals may be unaware of their bruxism unless informed by a bed partner or their dentist.
