bento teeth fitting animations

Are you trying out teeth replacers? Are you retexturing your teeth? Are you perhaps manifesting teeth from somewhere before reselling them like a strange teeth wizard?
You've probably noticed that 'very open mouth with bared teeth' is not typically on most animation huds for mesh bento heads. You've probably had a weird time checking your rigging, too, or deciding on purchasing a product you can't see well, especially if it's unrigged.

Here is two bento animations. One obliterates your lips off your face, and the other breaks your jaw wide open. Some people may find these useful! Enjoy.

Shown on LAQ Neve but any bento head should be fine, these animations aren't meant to be pretty.
