Are there any scientific studies that support what Weston Price had concluded. I read in an article that there is a blood test which allows to trace any bacteria from the root canaled tooth.
but it is still just an assumption. don't get me wrong, I read about a test that can trace back all of the bacteria coming from root canal and it is something we might look into.
here on this website it is mentioned: http://askthedentist.com/root-canals-know-before-you-go/
