Teeth grinding, or bruxism, is clenching or grinding without realising it. Many people don't notice — a family member hears it, or a dentist spots the wear on the teeth.
Possible signs
- Jaw or ear-area pain in the morning
- Headaches, especially at the temples
- Flattened, worn or cracked teeth
- Tooth sensitivity
Common causes
- Stress and anxiety
- Sleep problems
- Too much caffeine
- Upper and lower teeth that don't meet properly
Remedies
A custom night guard made by your dentist protects the teeth from wear. Reducing stress, avoiding caffeine before bed and keeping the jaw relaxed also help.
When to see a dentist
See a dentist if you notice worn or cracked teeth or jaw pain — a night guard early on prevents bigger damage.
