Hint 1
Match them up and mash them up — should be sweet! What are you chewing?
Hint 2
Sweet dreams and flakes of sugar — what to bring when you’re told not to bring a thing!
Hint 3
The clues each correspond to a tooth, as per ISO 3950 notation. The wisdom teeth are not important in this puzzle. Match the teeth and mash the words together. Embedded in each should be a Favourite sweet and an extra letter. Collect the extra letters to generate a question, and the answer is, well, the answer!
