The great mint hunt

In preparation for our 19 hour trip today, I packed the toothbrushes but no toothpaste! Thinking this wouldn't be a problem, we bought some at duty free in Amsterdam only to be told it had to stay in the sealed bag.......helpful.
Still not a problem (stupid rule but whatever) so we bought the "strongest mints" as recommended by a salesperson who could also tell us that we couldn't buy gum- it's not allowed here.
These are the mints. They happen to look like turds and taste pretty much the same.

Advice- Amsterdam airport sells good cheese and tulips. Bring your own dental hygiene gear and gum!
