Our bodies don’t usually have something to spare. We’re a pretty efficient machine that’s evolved to be that way, so save the appendix, we need pretty much everything to operate at the top of our game. Saliva is no exception. The more we study it, the more we realize that our spit is nothing to spit at. We found recently it can tell us that we’re getting some forms of cancer and diabetes before they really hit us, and that the the wet stuff helps keep bacteria at bay- but did you know the small amount of mucus in it is important as well?
The mucus that makes up about half a percent of our saliva was once thought to simply help keep spit together, but it turns out that that mucus coats our teeth and makes it so that bacteria simply slides off rather. So not only does the pH balance kill off potential bacteria, and the liquid in it help carry away the waste, the mucus coats and protects our teeth so nothing can happen to begin with.
