Dr. Price's seminal work. I bet that's him in FIG. 39. This stuff was known 80 years ago. If your dentist never heard the name of Weston Price, they obviously aren't keeping up in their field
And look at FIG. 41.... if they can file their teeth like that and not have any tooth decay, that says alot about the nutritional power of eating a natural diet, vs. the crap in most "grocery stores" today.
