Do you grind your teeth while asleep?

Do you have a sore jaw when you wake up in the morning? It might be due to grinding your teeth while asleep. — 123rf.com

I have recently been experiencing pain in my teeth whenever I bite on something hard. It is a very sharp pain, which then becomes a dull, but still painful, ache in my gums for a few hours. I went to the dentist, who told me my teeth are worn down because I grind my teeth. But I don’t!

Teeth-grinding is also called bruxism.
