I've always noticed that my son's teeth look ground down. I thought it was from all his trips and falls. Well, when we were sharing a bed in Oregon, I woke up to a horrible sound. I discovered that he grinds his teeth in his sleep.

I've never known anyone that does this. I know that there are those mouth thingys to prevent you from damaging your teeth. But he's only 6. I'd hate to see him have to wear that forever. Is this a habit that can be broken?
