Teeth grinding is a sleep disorder and affects one in every ten individuals. The problem is also referred to as sleep bruxism which describes the gnashing and grinding of teeth during sleep. It is a repetitive, rhythmic and involuntary activity of the muscle in and around the mouth.
Teeth grinders will grind their teeth two or four times per hour during their sleep, according to Maria Clotilde Carra, a Doctor of Medicine in Dentistry at Rothschild Hospital. The cause of bruxism is not well known although the condition co-exists with other disorders such as attention deficit hyperactive disorder, gastroesophageal reflux, obstructive sleep apnoea, sleep related epilepsy, restless led syndrome and autism.
