Symptoms
By Mayo Clinic staffSigns and symptoms of bruxism may include:
- Teeth grinding or clenching, which may be loud enough to awaken your sleep partner
- Teeth that are worn down, flattened, fractured or chipped
- Worn tooth enamel, exposing deeper layers of your tooth
- Increased tooth sensitivity
- Jaw pain or tightness in your jaw muscles
- Tired jaw muscles
- Earache — because of severe jaw muscle contractions, not a problem with your ear
- Headache
- Chronic facial pain
- 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
If you notice that your child is grinding his or her teeth — or has other signs or symptoms of this condition — be sure to mention it at your child's next dentist appointment.
