The Tooth Fairy is a minor character in Candy Crush Saga. She is encountered before level 336 in the twenty-fourth episode Pearly White Plains. Her teeth have been hit by a dangerous color bomb that has made them begin to yellow and decay. Tiffi promises the return of white, shiny teeth. After level 350, her teeth become sparkly white and she thanks Tiffi. In Moonshot Molars, she plays baseball with Tiffi using a color bomb as a baseball with score of 5-9.
The Tooth Fairy also helps characters pass levels that they need help on, by providing an extra life, etc.
In some lucky occasions, Tooth Fairy helps to unlock the episode after roughly 72 hours (Reality only).
Trivia
The Tooth Fairy appears in every episode checkpoint even though Tiffi officially meets her at level 336.
