Ahh yes, biofilms. These protein matrixes are like scum build-up in your bathtub for example. In the body, your immune-cells keep them under control to some extent by sloughing off cells underneath them. On other surfaces like mucus membranes, we have a slime layer--mucus which gives us protection. In the mouth, there are enzymes in the saliva which help control it, but some people have more trouble than others.
