Yeah my teeth hurt from clenching them due to stress and it can get worse the more stressed I am and sleep plays a big part in that. Ask your dentist.

Last night I fell asleep at 5:30. I woke up at 1. I planned on getting up at 5:30 but then at 5 I turned on Michael Jacksons Man In The Mirror and fell asleep from 5 until right before 6. So I still feel tired but not as bad with that hour of sleep.
