One day, while Does is fishing, his line gets caught on the decayed tooth of a shark. He pulls the tooth out and is rewarded by the shark. This makes Boes think that he might make a good dentist. He goes about fixing the teeth of the other animals, but ends up causing more damage than good …
Boes' haak blijft in de rotte kies van een haai hangen. Hij trekt de kies en de haai is blij. Boes 'de tandarts' behandelt andere dieren, maar doet meer kwaad dan goed.
