Okay, will stop using Blistex immediately. I've noticed that these areas don't 1) come to a "head" like a zit; 2) get crusty.

Her mouth will now be all white and "ashy/crusty" at the corners when she wakes up.....but that goes away when you wash her face.

Thank God we go to the dentist tomorrow. Maybe he can shed some light on this. I wonder if they still make the miniature boxes of Bag Balm...
