Grinding or clenching your teeth can be caused by a medical condition called Bruxism. This can be reactive due to lifestyle including excessive stress, anxiety or a habit during concentration. However it can often be unclear why people do it.
If untreated this can lead to damage to the teeth and/or Jaw, tension headaches, severe facial or jaw pain and Temporomandibular Joint disorders. It can also lead to a build up of excessive muscle mass at the Mandibular muscle (Jaw).
