American Dental Association answeredThe causes of bruxism are not known but many believe that stress, sleep disorders and an abnormal bite all play a role.
If you suspect you are grinding your teeth, schedule an appointment with your dentist. Your dentist can help you manage bruxism and its related symptoms, as well as repair and help prevent further damage to your teeth.
Honor Society of Nursing (STTI) answered
Among healthcare professionals, there is no consensus on the causes of teeth grinding. There are several suspected physical and psychological reasons. These include:
- aggressive or competitive personality traits
- suppressed strong emotions, like anger or frustration>
- improperly aligned upper and lower teeth
- sleep cycle changes
- side effects related to some psychiatric medications, including some antidepressants
- complications to some diseases like Parkinson's or Huntington's disease
For children in particular, teeth grinding may be a response to pain from an earache or teething, or a response to growth or development of the jaw and teeth.
Mark Burhenne, DDS, Dentist, answeredStudies have found that bruxism is found more frequently in individuals who suffer from Obstructive Sleep Apnoea (OSA). Grinding happens as the apneic event is ending. This is a rather new theory of why people grind their teeth.
It's important that you identify whether you grind your teeth, with the help of your dentist. That simple fact may lead to a diagnosis of OSA.
RealAge answeredNo one is sure why some people grind their teeth, a behavior also known as bruxism. However, most doctors believe that stress often triggers the problem, particularly if you don't know how to relieve it yourself (which could be a simple as talking about your feelings with a friend). Teeth grinding can be harmless, though it may also lead to serious tooth damage, jaw pain, and other problems. If you know that you grind your teeth, talk to your doctor about treatment options.
