Your mouth is a crucial interface between the outside world and the inside of your body. Everything you breathe, chew, or drink interacts with your oral cavity—the proteins and the microbes, including microbes that can harm us. When things go awry, the result can range from the mild, like bad breath, to the serious, like tooth and gum decay, to more dire effects in the gut and other parts of the body.
