Detoxing the body of toxins within the deep tissues and cells of the body have taken place over many years time, so yes a slow detoxification is recommended. However, if the source is the mouth, then it is best to remove it all at once or as soon as possible in order for the total body detoxification process can begin. For instance, imagine a piece of radioactive plutonium imbedded in your leg muscle. Would it be best to remove it a small piece at a time, or all at once? Until it is all gone, the body cannot effectively begin the detox process.
This bias may also be a result of the improper removal of mercury where a patient’s health took a turn for the worse. With the correct removal protocol, risk is very minimal.
