I think that is the theory behind the BLIS K12 products, as they try to populate the mouth with Streptococcus salivarius, which is found in non-bad breath mouths. That's only one type of bacteria though, and it doesn't seem to help most of us (I used K12 for 6 months with negative results, even worse breath actually). If they can come up with a more potent cocktail based on flora from 'healthy' mouths we may be onto something
