avery lost his first tooth. since then, he lost the other bottom one. he has had kind of bad luck because the first one he lost, in the literal sense. the second one, when blake was putting the money under his pillow avery caught him. so now when he shows people that he lost his tooth they ask if the tooth fairy gave him money for it and he says, "no my dad did." its pretty funny. blake tried to cover it up by saying that the tooth fairy gave him the money to give to avery because she was in a hurry, but he didn't fall for it.
