Huh? Actually, this is a pretty interesting article (linked to above) which is another example of how important healthy bacteria is to our health. Most of what we hear about is our gut bacteria which numerous studies have shown to be important. But whether we like it or not bacteria live pretty much everywhere in our bodies. And this story reports on a study that found that our mouth bacteria is also important. So mouthwash indiscriminately kills these bacteria causing things not to work quite as well. Similar to how antibiotics mess with our gut bacteria. So the takeaway is to be kind to your bacteria!
