Just an idea but havnt you ever considered having those teeth just pulled!
It would save you being bed ridden for a lot longer!
You could have saved yourself the last 2 years of misery by just having extractions which would be cheaper and totaly remove the cause of any future problems regarding refills and more toxicity.
After all its only a few teeth and no ones gonna be looking in your mouth except the dentist once in a while!
I personally have 12 huge silver Amalgams which are making me pretty damn toxic and so rather than pay out thousands only to have more bloody metal put in im going to have the lot ripped out.
I would rather eat soup for the rest of my life than be ill and unable to do the things i like.
Eventually i`ll get dentures but for now i just want my good health back and to hell with a few knackered old teeth.
