Hi, I live in London and there doesnt seem to be any labs that can quickly and effectively test samples of dental materials. The only option seems to be sending the sample and blood to the MELISA labs over to Germany or Belgium.

I was therefore wondering, having read something on wddty, that having a bit of the composite cured on the side of your tooth would be a good way of telling if you are compatible. If there was no reaction and everything was fine then the material would be ok.

Does anybody disagree with the above?
