What it’s for
- Protecting teeth affected by bruxism
The appliance and fit should be selected with a dental professional. A bruxism guard is not automatically an appliance for sleep apnea.
An oral appliance used to protect teeth from grinding or clenching.
Purpose, evidence and practical considerations.
The appliance and fit should be selected with a dental professional. A bruxism guard is not automatically an appliance for sleep apnea.
NIDCR describes mouth guards as a way to prevent tooth damage and potentially reduce muscle activity. That does not establish a cure for bruxism or a general sleep-quality benefit.
Confidence: weak
Persistent pain, tooth damage or concerns about fit need dental assessment. A guard does not establish or treat every cause of disrupted sleep.
The appliance separates opposing teeth to limit damage from grinding or clenching.
