HI Andrew, as you would know, there are undesirables in every dental material. No matter what you avoid, there is always something else to replace it that you may have issues with.

It is very difficult. You would be wise to have a serum test done. This has been mentioned already on this website. I put up all the information for somebody else to have this done. This will let you know whether it's showing an adverse response to your immune system or not. Everybody is different. I don't know if these tests are 100% accurate, or not, but they are "one" avenue you can go down and from there, you can always do further testing and find which materiasl come out best on most/all tests.

I know a dentist who uses the helio composite "heliomolar" and he feels so far it's been the least reactive on his patients and he is also trained in toxicity. He uses only two main materials - cerec porcelain, or heliomolar. I have Heliobond as my bonding agent, but I have cerec porcelain for the filling material. Because it's more-a-less permanent.

On my own serum test form "Helioprogress" has turned out "suitable". As have the other Helio products. all turned out suitable. But that may not mean it's ok for you. I am only giving you an example. It is said that it contains fluoride....but I had other materials that apparently did too "tetric ceram" and I had those replaced with something else and found it no better....if anything "worse". So I can't really tell you what is best.

You'll find a lot of contradiction out there too. I was going to get Heliomolar composites myself, until I decided to go to a local dentist here instead and pay extra for ceramics....Though your question is about helioprogress, I assume they are similar. They are made by the same company too.

Another thing you can do is get a hardened sample of the stuff and put it in your mouth for about a couple of hours or so eachday and see if you get any oral reaction or anything else that alarms you. Though bear in mind, it's more likely to react to this becaue it won't be bonded right into the tooth itself..... But it is one way of trying. And getting a sample and taking it to someone who uses an EAV (voll) testing. They can test that way too, aside from getting a serum test for yourself done.

I think they all have toxicity and it's just a matter of finding one that is probably least reactive to you personally. Also, with a mercury toxic body, you are far more likely to react to things than if you were not mercury toxic, so that's another issue and is why after amalgam removal, you really do need to be active in removing the mercury out of you. Also after amalgam removal many people get much worse due to the increased exposure of mercury from removals and the later stages of detox you go through when the body starts to dump the storage of mercury. Feels like re-poisoning and sometimes feels even worse than how you felt with amalgams. It's different for everybody.
