It appears that the bacteria of the mouth are remarkably similar throughout the world. There are differences, but they are mostly of a quantitative rather than a qualitative nature. Although much is yet to be learned on the regulation of the oral ecosystems, these quantitative fluctuations to a large extent seem to be induced by different dietary patterns: the food exerting a strong selective pressure on the oral microbiota.
