Hi there, thanks for letting me know. No, I didn't have diamond lite, I had diamond crown (though no doubt they are much the same) and even then I do not know whether to attribute my reactions to that, or dental office mercury vapor (though I had no amaglams just older composites at the time). I had a lot of odd symptoms, but as my health is now very vulnerable, it could have been the local anaesthetic or anything when I look back.

But even when I got them out, I did not improve and in fact got even worse! So who knows?

I'm not sure how much the Diamond range of materials is in comparison with the typical composites, but I do not think they are much more expensive, if at all. I had a quote from a dentist about them and it seemed they were much the same as any material.
