the proteolysis-chelation theory and was proposed by Dr. Albert Schatz. This theory suggested that enzymes (not bacteria) and chelating agents which are common in plants and animals (not acid) were the cause of tooth decay. In Dr. Schatz’s proteolysis-chelation theory, it is diet, trace elements, and hormonal balance that are key factors in triggering enzymes and tooth mineral chelation which results in tooth decay.19
