trust me if truly you have Badbreath then taking the precaution above will do little or no good to combating it...Everyone's breath ought to be as fresh as ever in fact you have tobacco users who even have a very fresh breath too.
some of them are not actually from the tongue like many doctors suggest, there are more things to it than meets the eye,majority of the ones I encounter are mostly from the digestive system and If that's the case, then I'm afraid using mouth washes and regular flossing or chewing breath mints will do no good.,
