Cerec, as far as I am aware is proving one very stable material. I have heard of grandio also and that is another good one as far as composites go. It's made in germany and they have a pretty good reputation for their materials. both tested fine on my serum test form too (and I am very chemically sensitive). Glad you got them! Any challenges removed from your immune system is an extra bonus. unfortunately I have a few problems with my existing materials and two are incompatible for certain and typicallyare filled in the biggest cavities. Filtek supreme is the name. Also one dentist viewed my xray online and thinks I have a very leaky filling also (composite).

Yeah your body could already be trying to dump some mercury from having much less in the mouth. and as it was done with full protection, it's probably enabled that to happen. At least you didn't get a whole pile out at once, which I reckon is dangerous even with protection.

Well whether it's the placebo effect or not, you've just got another source of mercury out of you...that's gotta be good either way.

Pity about the bridge! Do you know what it is? I'm curious about people's dental materials because I like to check them on my own list and see how they came up with me.
