Dental Biotechnology
The current theory is dental disease is an infectious process, which means bacteria are the cause of disease. Biotechnology teaches that it is the environmental conditions within the oral cavity that cause dental disease. It is the ecological imbalance of potential pathogenic bacteria to beneficial bacteria that results in dental disease. Not all bacteria are potential pathogens. In fact, only a small percentage may be pathogenic.  They are called potential pathogens because under certain conditions, even these bacteria are harmless (Ewald "New Germ Theory"). Louis Pasteur, originator of the current Germ theory, admitted before he died that it is the soil, not bacteria that cause disease. The soil is the environmental condition within the body. 

The key factor to environment conditions may be called the ABC of the body or the Acid Base Chemistry. Acids are associated with protons and the process of reduction.  Bases are associated with electrons and the process of oxidation. Good health results from a balance of Acid Base Chemistry. It is the ABC that determines if pathogenic bacteria become destructive or harmless.
