One in three, maybe one in five adults in the United States think they grind their teeth while awake. Stephen: I don't know what it feels like to grind my teeth because I didn't know I was doing it until my dentist said you're grinding your teeth into dust. What about your husband? He's right there. You can apparently hear when somebody's teeth are grinding against each other if you're listening closely and it's a very quiet room.
How can you break a bad habit if you’re not aware that you’re doing it? Does Barack Obama grind his teeth? And is Angela’s dentist a crook?
