Hi there,

You're welcome

Any blood testing lab should be able to follow the instructions on the blood serum test. I had it done in nz. They just had to figure out how to go about it and what time I should go in and collect it etc.

Cerec is a pretty general biocompatible material. It is a good quality material good for large cavities etc. It also expands and contracts in heat/cold. So you would not likely require a test for cerec as I hear it's pretty much non allergic.

However, all dental materials contain toxins/chemicals/metals of some kind or another. Being a ceramic/porcelain, Cerec would contain aluminium oxide. Though it's a non metal form of aluminium. Here is a link about aluminim oxide in dental materials:

Some people just have cerec in the large cavities and use a biocompatible composite in the smaller ones. Depends also upon finance. Cerec is highly expensive, though you do get what you pay for. It'll likely last up to 20 years or so if it's placed right by an experienced dentist.

I'd personally opt for cerec for this particular job, because yes, it would enable you to get rid of the palladium and any possible leftover amalgam underneath at the sametime. Not a bad idea! Read up more about cerec and it's biocompatibility if you're not sure. But yes, it is a non metal restoration. So that in itself makes it a better option than a metal based crown. It is solid ceramic. I don't know if I'd get every tooth done in cerec however. They all have their own effects on our bodies/systems to some degree, so perhaps too much of one main material is not always a good thing? Just a thought.
