For anyone who has read about Weston A Price and his book on dental work will know, raw unpasteurised butter and raw milk products are possibly the best thing for peoples teeth to eat and for all the bones in you body, and may even regrow the cavities and strengthen you teeth enamel significantly.

Here is the link.

For anyone who doesnt know what I am talking about, the book is called Nutrition and Physical Degeneration, and the book is based mainly around the health of teeth, and bones, but specifically teeth.,

Im sure the book has been mentioned before on this forum, and a google search of the book will make you see what I mean. It was written in the 1930's for anyone who doesnt know what I am talking about btw.
