Nothing's more important to Samantha than good dental hygiene. She'll do anything to get that perfect, celebrity smile, and if there's one credo she lives by, it's to brush and floss her teeth three times a day. And nothing bothers her more than her last, crooked baby tooth that refuses to fall out no matter what she tires. Lately, it's becoming more of a nuisance than ever, especially when he eyes fall on Tommy Gunn, the new boy at school. When Tommy quickly makes friends with Samantha's older brother Billy, she thinks she's a shoe-in. That is, until her best friend Jessica gets in the way. A big problem to be sure, but nothing clever Samantha can't fix!
