The story of Jens and his troubles with the two tooth trolls Karius and Bactus has entertained families for seventy years. The play is based on a Norwegian children’s novel written and illustrated by playwright Thorbjørn Egner and first published in 1949.

The names Karius and Bactus are puns on Caries and Bacteria, the two main characters leading a luxurious life in Jens’ teeth, especially while Jens maintains his awful diet of white bread and syrup – and constantly fails to brush his teeth…! 

The play is approx. 45 min. long and is in Icelandic.
