Weezer frontman Rivers Cuomo has been ordered to wear a night guard by a dentist in a bid to stop him grinding his teeth while asleep.
The rocker went for a check-up at a dental practice and was told he grinds his molars together at night, and he'll have to wear the uncomfortable mouth piece to prevent the habit.
Taking to his Twitter.com page the musician writes, "I have to wear a night guard now cuz my dentist tells me I grind my teeth."
