Well, there are lots of ways to lose a tooth: a punch in the mouth, a face-first fall on the sidewalk, or a career as a hockey player if you want to make it fall off in a celebrity style. But this one way is particularly iconic: tying one end of a string to the tooth, the other end to a doorknob, and then slamming the door.
Watch how the Dad safely instructs his daughter, who is bent on having her tooth slammed off using a door, and asks her if she is sure to do this trick! And then he… BANGS the door to pull the string attached to the tooth!
Altleast, the entire process ends up in giggles and smiles, and not in tears as usual!
