Rhys Leslie  asked the Naked Scientists:
   
Hey Guys, 

I am a teacher from Australia and have a quick question for you about drinking.

If you have had a big night out, when you wake up the next day with a dry mouth, there is often a solid substance lining the inside of your mouth. Could you tell me what this is?

Thanks

Rhys

What do you think?

Alcohol is a drying agent and causes sloughing to occur
