In most cases, bruxism doesn't cause serious complications. But severe bruxism may lead to:

  • Damage to your teeth (including restorations and crowns) or jaw
  • Tension-type headaches
  • Facial pain
  • Temporomandibular disorders — which occur in the temporomandibular joints (TMJs), located just in front of your ears and felt when opening and closing your mouth
