Derek Thompson is a minor league hockey player nicknamed the "Tooth Fairy" for hitting opposing players so hard that he knocks out their teeth. One night, Derek steals a dollar from his girlfriend Carly's (Ashley Judd) six-year-old daughter Tess that had been left for her lost tooth and tells her that the tooth fairy doesn't exist. Then he receives a magical summons under his pillow. He grows wings and is transported to the realm of tooth fairies. He meets his case worker, Tracy and the head fairy, Lily. He has an adversarial relationship with them. Lily tells Derek that he is a "dream crusher," due to his unsympathetic dealings with children like Tess. He is sentenced to serve two weeks as a tooth fairy. Later, he meets Jerry, who gives him his tooth fairy supplies, which include "Shrinking Paste," "Invisible Spray," and "Amnesia Dust." Carly's teenage son, Randy dislikes Derek. Randy wants to grow up to be a heavy metal star. When Derek defends Randy against a bully, he begins to win him over, and Derek begins teaching him to play his electric guitar better so he can win a talent show. Derek visits several children and tries his best to be a good tooth fairy, but ends up causing more harm than good. Lily says that he is the worst tooth fairy ever and denies him more supplies for the remainder of his sentence. He buys black market supplies from another fairy named Ziggy, but they malfunction and he is seen by a child's mother and arrested. While behind bars, Tracy tells Derek that his duty is extended to three weeks. Carly bails Derek out.
