Maybe we should look at the Root of the problem in order to understand the overall problem with mecury fillings ?
Now, let us look at what may be the case as to "WHY" some people with mecury fillings may have problems and becommed Poisoned from them and other people do not seem to have any problems !
"IF" you checked everyones Saliva pH who has mecury fillings, you may find that some people have a Less Acid pH , while most others, especially those having problems , may have a "VERY" Acidic Saliva pH !
When the person has a very Acidic condition in their body, this may allow for Decay to set in , in your teeth between the areas of contact between the tooth and the mecury filling which then produces a steady supply of Bacterial Acids, which may work at causing a Release of some of the mecury into the body and thus cause you problems !
But, "IF" you are healthy or "IF" you become Healthy after you had become sick enough to have fillings put in your teeth in the first place, then when you are able to raise your pH enough so that your mouth does not stay or continue to be Bathed in Acids from an Acidic Saliva, then your Saliva may correct any temporary condition of Acidity which may be caused by taking Epsom salt or Lemon juice or ACV or such foods which may carry Weak Acids !
The problem may be in that when the persons Saliva is not Alkaline enough, that this may allow for corrision of your Teeth and also the mecury fillings !
But, when you learn to correct your eating Habits enough , so as to allow your Saliva to become more Alkaline , as it should be, then you should not have anymore problems from the mecury fillings Releasing any Posion into your body !
For, "IF" your body was Healthy in the first place, so that your pH was up where it should be and your body was getting the needed Alkaline Minerals for your teeth, then you would "NOT" have gotten "ANY" tooth Decay in the first place !
Smile Tis your choice.
