(HealthDay News) — Tooth grinding can lead to headache, jaw pain and may even crack your teeth.

Stress is a common trigger, especially during sleep.

If you grind your teeth, the American Dental Association suggests:

  • Wear a custom-made mouth guard while you sleep.
  • Talk to your dentist about the possibility of taking a muscle relaxant at bedtime.
  • Get psychological therapy if your stress or anxiety is serious.
