Bruxism is the technical term for teeth grinding and jaw clenching that abrades teeth and may cause facial pain. People who grind teeth and clench jaw, called bruxers, unintentionally bite down too hard at inappropriate times, such as in their sleep.
Many children and adults grind their teeth unknowingly during their sleep. It can result in chipped, broken and reduced teeth, loose teeth and receding gums.The force of clenching causes stressful pressure on the muscles, tissues and jaw. Jaw disorders, jaw pain, soreness, headaches, earaches, damaged teeth and other problems can result from bruxism.
Bruxism can even affect one’s sleeping partner, as the noise can be loud enough to prevent him or her from getting a good night’s sleep.Nobody knows exactly why some people have bruxism and others don’t. It is most common in small children. And this may have some basis in the tooth losing process.
