Rabbit/Bunny/Mouse Teeth?

I've started my first every fursuit and they are a Dumbo Rat. They have those big toony rat teeth that most other characters do.
I'm having a hard time figuring out how to make these teeth. I know some makers sell them but they seem too small for the look I'm going for.
I would assume they would just be made out of fleece, right?
