If you have proper dental hygiene there should be no smell from your mouth besides after spicy foods/ onions/ garlic etc. until you brush of the plaque. Or if you are sick (that goes mostly from the bacterial disbalance, the stomach etc.)

Of course, the minty freshness is nice to have but that is just a bonus. Most people rely on this to cover up bad hygiene but a proper dental hygienist will of course see the problems either way.

If you search my comments, I have written about dental hygiene at length. Source: my fiance is a DH, see neighbouring threads.
