It's INCREDIBLE! And having just done a cake along these lines (although NOWHERE near as good) it makes me appreciate even more, what talent they have. I'd love to email and let them know how brilliant I think this cake is!
But having Googled 'teeth cake' and then looked on images, this photo pops up all over the place, but I can't see who it's by....
cant help with the cake mystery.. but love your signature! LOL
I've seen it on Ace of Cakes.. But everybody's had a go at this... so couldn't tell who this one belongs to. Quite popular!
Edit: I agree with PP. There are plenty of sites that show her cakes, but her web site is elusive.
