Hi there 2scoops, I know someone who has had the same thing. Pain after Amalgam removal and in fact I have just been contacting them via email and asking how it is. They have had to take pain killers for weeks since removal. I gather they got Diamond replacement materials, which I hear can have the drawback of post sensitivity, but thought it was only temporary.
What materials did you get? This is not good and a very big concern. I have heard of it a few times now from people online. perhaps this is what of the problems with some composites.
