1 min read · 7 October 2026
Many people grind or clench their teeth, often during sleep, without knowing. Over time it can wear and crack teeth and damage fillings and veneers.
Signs to look for
- Flat, worn or chipped tooth edges.
- Jaw pain or tiredness in the morning.
- Headaches near the temples.
- Sensitive teeth.
- A partner hears grinding at night.
Common causes
Stress, sleep problems, a high caffeine intake, smoking and sometimes the bite. In children, grinding is common and often stops on its own.
What helps
- A night guard made by the dentist protects teeth from wear.
- Noticing daytime clenching — teeth should be apart when relaxed.
- Less coffee and energy drinks, especially in the evening.
- Relaxation before sleep.
- Repairing worn or cracked teeth early.
Grinding and cosmetic treatment
If you grind, veneers and crowns can chip. Tell the dentist before veneers so a night guard can be part of the plan.
