The excrement from the anaerobic bacteria is the taste and smell in the mouth upon waking up in the morning. Not only is it acidic, it also forms a sticky hydrophobic (water resistant) shield around the tooth, called plaque. This is why water alone does not work to remove plaque. In addition, gums act like a gasket around the tooth, further preventing air or water to reach the anaerobic bacteria along the gum line. Something else is needed to break through the grease barrier.
