|Bruxism refers to an excessive clenching together of the bottom and upper jaw accompanied by the grinding of the lower set of teeth with the upper set. Most people are unaware that they are grinding or gnashing their teeth because it frequently occurs at night (referred to as Sleep Bruxism). Usually it is only when someone points it out that people with Bruxism become aware that they are grinding their teeth.
Bruxism affects adults and children and, although not usually a serious medical problem, it can wreak havoc in the mouth - causing teeth to loosen and become painful. Parts of the teeth sometimes break having been ground away completely. This can lead to jaw joint disorders, pain, headaches, earaches, damaged teeth and abrasions in the mouth.
