Ah dunno but your breath has a

lot to do health, diet (Atkins diet followers are know for ultra bad breath) and the the presense of certain

bacteria on gums, teeth, tongue and throat. If you eat a little yogurt daily the "friendly bacteria" will help nix

some of the funk. However many folks have a stomach condition whichs allows the smell of stomach juices to ventilate

through the mouth, so no matter how clean their mouth, the breath is still bad.
