Derek Thompson (Dwayne Johnson) is a close to washed-up ice hockey player who is affectionately known as “The Tooth Fairy” due to his ability to wipe out opposing players on the rink, an action that usually results in their loss of teeth.

Having long ago given up the dream of ever scoring during a game, Derek is happy to lap up the adulation he receives from the crowds for causing such carnage. However, when Derek’s overly pragmatic approach to coping with life by having low expectations results in him telling a young boy to also abandon his dreams, Derek is magically taken to Fairyland where he learns that he must atone for his dream-killing sins by doing time as a tooth fairy.

The tough guy having to deal with the world of children comedic scenario has been popular since Arnold Schwarzenegger’s stint in Kindergarden Cop in 1990. Just the contrast between the tiny physiques of children to the muscular and hyper masculine body of action stars, like former professional wrestler Dwayne Johnson, provides a basic degree of amusement. Throughout Tooth Fairy Derek has to somehow reconcile the delicate world of fairy magic with his bulky and destructive presence and most of the gags in the film are bull-in-a-China-shop type situations as he screws up various attempts at retrieving teeth from under the pillows of sleeping children.
