Oral hygiene is something that has to be taught from an early age, but it is not always easy. Chirpy Charlie watches her human friend brush her teeth every day and he wants to do it too, but he has a problem: he is a bird!

Every morning mom yells at Julie: "Julie, brush your teeth, or you'll need a filling!" Well, I'm a little bird who looks after his health, and all this business about getting a filling must be horrible, because she talks about it every day. There's no way I'm going to have one of those things in my teeth. Chirpy Charlie can be many things, but irresponsible is not one of them! But how do birds brush their teeth? Excited, he searches for information on the Internet and consults all the encyclopedias at home, but he does not find any answer. He discovers that other animals brush their teeth gnawing on wood or chewing on some seaweed, so he decides to give it a try. Result: a failure. Will Chirpy Charlie find a solution for him?
