Nothing much. It isn't like your throat is going to rot away or anything, but I guess that depends on how wide you open your mouth. If you open your mouth as wide as it can go for weeks on end, it is very unhealthy for you for dust and other particles (life forms even) can go in and that wide open mouth probably means that you have trouble time breathing and need medication. Also, it will suck if an insect fell in but I'm pretty sure all these possibilities won't happen to you if you only slightly open your mouth while sleeping.
sometimes you sleep with your mouth open, and you breathe alot all night so your throught is kinda raw.learn to spell throat.
open mouth
Probably not; it would have to be VERY cold to cause a sore throat. A more likely explanation would be humidity; if you sleep with your mouth open, then your throat can become dry if the air itself is dry. Put a humidifier in your bedroom to keep the air at least 35% relative humidity. Or, keep your mouth closed and learn to breathe through your nose when you sleep. It's better for you, anyway.
You snore and sleep with your mouth open. Try changing your sleeping position or take some anti-soring or anti-congestion medicine.
