erm... I feel like those pointy things (If I got the right guy, I can't open photobuckets at school and I'm assuming he's the crazy blonde with spastic vampire teeth ALL OVER HIS MOUTH) would need to be made by a dentist.
Else you'd need to make a mold of all your teeth and thend make spiky ones to go over it.
Seriously though, he looks like he filed each of his teeth into points like that guy from Sleepy Hollow with Johnny Depp. You might not be able to recreate it with... er... teeth. Having them, at least. You can't quite get the spaces without ripping out all of your teeth and replacing them ^^;
