i've had a couple of dreams where i was missing teeth. i had a dream once that i got my front few teeth knocked out of my mouth in a fight or something. then i had a FA, and my teeth were still missing. so i went and told my brother that i had just had a dream that i lost my teeth, and then i woke up, and they were still gone! he thought that was pretty weird. then i woke up for real, and, of course, the first thing i did was check my mouth to make sure i had all my teeth!
