Price's extensive research is something I became familiar with a few years back, his works is just among the stuff I found while I was new into the process of becoming self-informed on a variety of topics - health/dental just one. This particular part of the process is what lead up to my decision to have all dental metals removed. Since this time, I've had all amalgam fillings removed, continue to progress towards having root-canaled amalgam-nubbed crowns removed, and I continue to study and research on various fronts in the war on becoming self-informed, including on dental issues, and have found myself a bit conflicted over what appears to be the truth & story with Price. Yeah, he did a very broad and long, extensive study related to various health issues, having documented a TON of valuable information that COULD be beneficial for the average person to be informed of, including diet and dental info. While he was able to get a lot of this information into a book, he also did fairly well in helping the establishment keep (for many years) much of his research mostly buried & hidden from the general light of public scrutiny. Keep in mind Price did a lot of his research between the 20s and 50s, and it's now 80-some years into a new millenium that many of us are just now becoming familar with who he was and what he did....... what's up with that? A lot of mercury has been un-earthed and re-planted inside human mines, a lot of Post & Core jobs, etc, have occured over the intervening years.
