Toothpaste flavor (4)
I believe the answer is:
mint
'toothpaste flavor' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mint that I've seen before include "Coin-making place or nice lamb sauce" , "Large sum of money" , "sweet to suck?" , "Produce coins" , "Money-making herb?" .)
