I've been using Tooth Mousse which seems to be the same sort of thing only it is available here in Australia. It doesn't seem to be helping much and the dentist told me that it helps some and not others. :( I may continue with it just in case it takes me longer to experience improvement.
Reading briefly about the IP6, it sounds like it would detox metal. I can't risk taking anything that might do that. I have read that when one has mercury in the teeth it is dangerous to chelate metals. Plus I don't detox well at all thus the reason I'm experimenting with the simplified protocol for opening the methylation pathway. Even that is painful and going very slowly. http://health.groups.yahoo.com/group/CFS_Yasko/
