Re: Crowns of death.

I think the health problems are related to having a rotten tooth at the end of a meridian not a missing tooth.
My grandmother had no teeth for half her life and she lived to 96 with no real health problems till she was 90

I once read in a macrobiotic book that pulled teeth result in irritability, not sure if that's true

Then again if you are in very good health get enough Iodine etc and do meditation or qigong to strengthen and cleanse the channels then even a root canal may be rendered harmless
