Tumbloni trash render

The daily renders may turn into the "if I get around to it" renders. But I have this, rendered a week ago, so I'll post it.

I was looking at the teeth deformation on my Tumbloni (Tumblr tag search, not necessarily safe for work). I got those wacky cuspids from some old image of an ogre, but they don't make a lot of sense. How can I close my jaw with those? If I use this oni design again, I think I may change them.
