I've used this game with kids of all ages, including children with special needs. It's a good idea to demo the game first to show them what happens (and the unpredictability). Kids that have issues getting their finger "bitten" can use a pencil or popsicle stick to press down the teeth. The end result is always lots of laughs. On the adult front, it could be a good drinking game :)Get more detail about Crocodile Dentist.
