I highly recommend reviewing Prices account of his studies in the field: http://gutenberg.net.au/ebooks02/0200251h.html http://gutenberg.net.au/ebooks02/0200251h.html His conclusion was quite different: that the cause was a lack of nutrients in the modern diet. It is difficult to point to an example from his work that would clearly rule out the theory of chewing in this article. Sugar and white flour that he pointed to are both easy to chew and low in nutrients. However, it is hard to think of lack of chewing as the primary factor in tooth decay, and Price was focused first on decay rather than crowding. Price did note a very strong relation between decay and crowding, and in that light it is difficult to view lack of chewing as the primary force in either decay or crowding.
