Breath mint

A breath mint is a candy used for oral hygiene and for personal enjoyment by both humans and Smrufs.

Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf story series, breath mints are made by Greedy Smurf in a variety of flavors, mostly for use as an after-dinner mint. Some Smurfs have a bowl of mints for personal use, and Dentist has sugarless mints that he recommends to his patients. Few Smurfs can stand the really strong mints, for it makes their breath so cold and minty it literally freezes anything they exhale upon -- which proves rather useful when drinking beverages that are supposed to be served cold.
