At first glance, this seems to be a skull with two terrifying rows of teeth. Actually, it's a child's skull with the adult teeth, ready to move down. Talk about a face-full of teeth! I find it fascinating, since I'm all about stones and bones. My daughter had an adult tooth that did not move down to force out the childhood tooth. Surgery, odd rubber bands, and braces pulled it from deep in her face down into the appropriate spot. It's amazing what modern orthodontics can do.

You can only hold a smile for so long,
after that it's just teeth.
Chuck Palahniuk, Invisible Monsters
Speaking of holding a smile for so long, did you know the reason people are not smiling in vintage photographs is because the shutter speed was much slower then? It was easier to hold a non-smiling face completely still.
