1. The amalgam placed in root canals or apicoectomies is the words of Mark Breiner, DDS (although we have had patients here with it).
2. When I say an apicoectomy is essentially a root canal, that is right out of the mouth of a Biologic Dentist, and what it means is, that they are damaging roots, and eventually the abscess that was there in the first place, will come back (if you do not have a root canal, yet). But most apicoectomies are done to remove infection from failed root canals. They are a temporary solution and treat the symptoms, not the cause.
3. This is from a Biologic Dental perspective. But, the fact that mainstream Dentistry ever used mercury in root canals and apicoectomies says a a lot about mainstream. So, even if they are not using it now, it is good for people to see it was used. It is still in a lot of people out there, and many are ill from it. But that article by Mark Breiner is from 2001 and he says they were requiring he use the mercury in certain apicoectomies, so it obviously was going on around that time.
