No, I haven't read this book yet, but I am thoroughly convinced that virtually everything dentists do to your teeth - short of extractions - is BAD for you in the long run. Reading the previous post, that even porcelain is BAD, sort of did it for me.

I have several teeth missing, making it necessary for me to choose my diet carefully, ie, no hard, crunchy foods - which would not be good for me, anyway, because I have a few very old fillings hanging around.

Never mind the biocompatibility testing - I am not having anything artificial placed in my mouth ever again. If that makes me a toothless old hag in the years to come, so be it. I am not at all impressed with what passes for "teeth" nowadays, anyway - they look more like giant, whiter-than-white chiclets. For those of you who may not know, Chiclets are a brand of rectangular shaped pieces of gum.
