i do not know what might be causing the bright white marks on your front two teeth. to get more information you can ask this of your dentist. when you sleep with an open mouth you are probably experiencing a problem with the air passage through the nose. this might be caused by inflammation polyps or septum deviation. you can go to an ent-specialist for a rhinoscopy to investigate your tendency to sleep with an open mouth.
hi i have an enquiry mostly every morning when i wake up and look in a mirror i see bright white marks on my front two teeth. they do dissapear after 3-4 hours but then again next morning they re-appear. i always think for some reason that its cos i sleep with my mouth open and breathe in from my mouth. could you please tell me why these marks appear and how i could prevent the white marks from appearing every morning. thanks in anticipation<positive_smiley>
