You can take them to someone that has a EAV machine (voll) and get them energetically tested to see if they suit you. You can also get them muscle tested (someone who is experienced/naturapath or someone).

you can also do a cheek and gum test by putting the sample in your mouth for a few hours a day to test for any oral reaction (or anything else).

You can also find out the names of these materials, then order a serum test from a serum testing lab. E.g. The Clifford lab in US run by Walter Clifford. They test just about every known dental material there is (composites, bonds, linings, porcelain/ceramic, gold, braces, the whole deal). And all you have to do is get a sampe of your blood serum in a tube (you will get the instructions on what to do) and send that to them.

They will test your serum against all these materials and send you back the booklet of results. You will either see an "S" or a "NS" next to the materials. S means "suitable" and NS means "not suitable".

It will help if you tell the lab the specific materials you want tested as well. even though they will automatically test you against the hundreds they already have, it is wise to give them some specific examples just in case. If they happened not to actually have that material, they could then get hold of it.

Let me know if you need any further information. I'll find out what I can for you.
