I know what you're saying, it's trying to pick the lesser of many evils. These tests may well be a waste of time and money, but you can see the desperation of people. You reach a point where you become almost paranoid and grab at anything.

At onetime I was quite careless about these things, but once my health hit rock bottom, I look back and wish I had done things far more carefully.

I would probably tend to go for the more up-to-date porcelains like cerec, but again I still dont know what affect that will have on me. It looks promising, but nothing is a sure thing.

The fact is it's harder and more stable than amalgam or composites, but that's not to say nobody is going to react to it. The problem are the older style ones that they put in with metal bases that can sometimes cause problems for people. THe other worry is the aluminium in porcelain, yet I hear that the newer ones like cerec are not such a problem in this area. They are not quite like the old ones and do not have metal bases needed.
