I have heard that necessity is the mother of invention. So what do you get when you bring together a dog that loves to play 'fetch', a young daughter with a loose tooth, a piece of string and a clever dad with dark sense of humor? The video you will find after the jump.

 

The little girl's name is Ava and the dog's name is Clancy, or as we now know him, the 'dog dentist'! I hope the Tooth Fairy was generous.

My brother and i used to tie strings to door knobs and then slam the door to get loose teeth out. Did you ever do anything crazy to get rid of loose teeth?
