First, start by biting into an apple several times. Depending on how lose your tooth is, this may become too painful.
Second, wiggle it numerous times, moving it forward and backward, forward and backward. Repeat this step as needed.
Sometimes your dad can unexpectedly take charge of the tooth losing process. If this is the case don't panic.
Because your dad has stepped in, you are able to skip to the final step which is, "yank really hard." Works every time!
