Those of us who are of a certain age will remember Gnasher from the Bash Street Kids, has it ever occurred to you that perhaps Gnasher was called Gnasher because he suffered from Bruxism, or more simply, Teeth Grinding!

Bruxism (from the Greek βρυγμός (brygmós), “gnashing of teeth”) is characterized by the grinding of the teeth and typically includes the clenching of the jaw. It is an oral para-functional activity that occurs in most humans at some time in their lives. In most people, bruxism is mild enough not to be a health problem.[1] While bruxism may be adiurnal or nocturnal activity,[2] it is bruxism during sleep that causes the majority of health issues; it can even occur during short naps. Bruxism is one of the most common sleep disorders.[3]

Most people are not aware of their bruxism. Only an estimated 5% go on to develop symptoms, such as jaw pain and headaches, which require prompt treatment.[4] A sleeping partner or parent may notice the behaviour first, although sufferers may notice pain symptoms without understanding the cause.

Patients may present with a variety of symptoms, including:[5]

  • Anxiety, stress, and tension
  • Depression
  • Earache
  • Eating disorders
  • Headaches
  • Migraines
  • Loose teeth
  • Tinnitus
  • Gum recession
  • Neck pain
  • Insomnia
  • Sore or painful jaw
