I did my first one or two Liver Flushes before my dental cleanup and it went fine. I think the Liver Flushes are so essential it's better to do it right away.
I also think the dental cleanup is very important. It's hard to go wrong on a liver flush. Just do it. The dental cleanup however, requires research since doing it wrong will cause you more problems than leaving it alone. If you don't believe that, just go to the Amalgams forum and read about all the problems caused by going to dentists who didn't follow the proper protocol that Dr Clark describes. On the other hand if done correctly it can get rid of problems you would have never in a million years thought was caused by your teeth. I unexpectedly got rid of my Arthritis permanently when my dental revision was done. You can call 1-866-948-4638 to get a referral to a dentist that will follow the proper protocols.
Here are two links to start with. The first is to Dr Huggins website and the second is my post about getting my dental cleanup. Good luck to you!
