I had all of my root canals removed and they found huge roots infected with puss leaking back into my system this alone did not cure my nocturnal seizures, this and Liver Flushing did.
you can go to the ASK TORRIE forum now it's ASK Aharleygyrl for lower cost dental treatment
also, find a kinesilogist and get to the root cause of his illness http://www.icak.com
my guess it's either the amalgams, or the roots are infected and leaking back into his system making him sick
or he needs to cleanse his liver via this forum under cleansing or http://www.sensiblehealth.com
