Bruxism or Teeth Grinding- Causes, Symptoms, and Treatment

If you grind your teeth a lot, and you wake up with pain in the jaw, neck, or head, then you may have bruxism. Sometimes a person is not even aware that he or she is grinding or clenching their teeth at night until a routine dental visit reveals significant tooth wearing or damage to restorations. Bruxism can be treated effectively with the help of a nightguard.


You grind or clench your teeth once in a while and it doesn’t cause any harm. But if you regularly grind your teeth, then it can hurt your jaw muscles, TMJ, and teeth. The excessive clenching of the jaw or grinding of teeth, which usually occurs while you are sleeping is called bruxism or teeth grinding.


  • Emotional stress or anxiety- Stress, anger, anxiety, or tension which is experienced during the daytime can be carried over to sleep and many people grind their teeth repeatedly or clench them unknowingly during sleep.
  • Caffeine and alcohol consumption
  • Smoking
  • Sleep disorders such as sleep apnea or snoring
  • Medications
  • Diseases like Parkinson’s disease, GERD, epilepsy, etc.
  • Heredity


Sleep bruxism

In sleep bruxism, you clench your teeth while sleeping which may cause more harm as you are unaware of how strongly you are clenching your jaw and teeth.

Awake bruxism

Awake bruxism is more common in adults who work under stressful conditions. You clench the jaw and teeth during the day if you are stressed, angry, or even at the time of over-concentration in this condition. It can be treated with the help of stress management and learning ways to notice and stop the grinding of teeth.


Bruxism is hard on your teeth, jaws, and muscles. According to an estimation, people with bruxism apply six times more force than normal forces while biting or clenching.

Tooth damage can range from cracks in teeth to fractured teeth leading to pain in teeth and even tooth loss in worst cases.  Bruxism can lead to broken teeth, filling, or a crown. It can lead to changes in your facial profile and your looks (due to reduced height of teeth). The stress from bruxism can also damage the supporting tissues like gums and muscles.

The other signs and symptoms of bruxism are-

Teeth grinding is possible in children too like adults. Parents usually hear the sounds of teeth grinding of children during sleep. Sleep bruxism can develop as early as 4 years of age, but it peaks around 10 to 14 years of age.  Children may outgrow the bruxism by the time they lose their milk teeth. Stress is the main cause of bruxism in adults but in the case of children it may be due to

  • Allergies

  • Maintain a gap between upper and lower teeth: Place your upper and lower teeth mindfully so that there is a gap between them except while chewing to avoid teeth grinding. Try doing this exercise for the whole day.
  • Jaw exercise: Open your mouth wide open and try to touch your front teeth with your tongue. This will help in relaxing the jaw muscles.
  • Warm compress- Put a warm washcloth against your cheeks for 15minutes on one side and then on the other. It can relax your jaw muscles by increasing the blood circulation in that area.
  • Avoid chewing pencils or pens.
  • Avoid chewing gums and frequent snacking.
  • Maintain a proper posture by sitting straight, with your head up and shoulders squared.
  • Stick your tongue between your teeth

Mantra for avoiding teeth grinding:

LIPS TOGETHER, TEETH APART! (This would prevent excessive pressure from being applied to jaw muscles due to teeth clenching)
