When pizza burns the roof of your mouth and "skin" dangles down, what is that?  Is it actually skin? Some other type of membrane?  Does it scar?

It's a layer of mucous membrane that's been killed by heat.  Not skin, but similar.

Wounds inside the mouth tend not to scar too often or very much because most of the tissue in there regrows fast, and is kept moist while regrowing, which prevents scabs (which actually slow wound healing down a bit.)
