Signs and symptoms of bruxism may include:

  • Teeth grinding or clenching, which may be loud enough to awaken your sleep partner
  • Teeth that are flattened, fractured, chipped or loose
  • Worn tooth enamel, exposing deeper layers of your tooth
  • Increased tooth sensitivity
  • Jaw or face pain or soreness
  • Tired or tight jaw muscles
  • Pain that feels like an earache, though it's actually not a problem with your ear
  • Dull headache originating in the temples
  • Damage from chewing on the inside of your cheek
  • Indentations on your tongue
  • When to see a doctor

See your doctor or dentist if:

  • Your teeth are worn, damaged or sensitive
  • You have pain in your jaw, face or ear
  • Others complain that you make a grinding noise while you sleep
  • You have a locked jaw that won't open or close completely
  • If you notice that your child is grinding his or her teeth — or has other signs or symptoms of bruxism — be sure to mention it at your child's next dental appointment.


What is teeth grinding?

Statistics HistoryBruxism or Teeth Grinding is a condition in which you grind, gnash or clench your teeth. If you have bruxism, you may unconsciously clench your teeth together during the day, or clench or grind them at night (sleep bruxism).

Different sounds:

1: Very clear long repeating grinding sound.  

The jaw muscles are very active and the sound is very clear and present (mixed episodes), toothwear is often very visible in the mouth.

2: Clear short repeating grinding sounds

The jaw muscles are active during a period of your sleep, not contracting all the time but in short episodes (phasic episodes) 

3: Very short unclear grinding sounds

The jaw muscles can be active, but more static (clenching). the sound is often a very short sound (tonic episodes)
