The problem is, what else can they use to bond the material in place? It has to be a strong glue, that is all they have. So what choice do we have?

i would love it if all they were putting in was the cerec material, but yeah I have to have the bonding agent with it and I don't see how I can get out of having plastic, as this is the only thing they can glue the material in place.

The only solace I get from that is, I'll have less plastic than before, as at least the composites wont' be there. With composites you get bond, lining and the composite itself, so with the cerec, there is less of the plastic. It's not perfect, but unless someone can come up with what else can be used to glue materials in the teeth, I'd be happy to hear it. I dont' think such a product exists. Either you get gold in or leave the amalgams in, or you have to go wtih a product that needs bonding to the tooth.
