You most definitely do have a chance! You also have youth on your side and it's wonderful you have caught onto this so early. I started to figure it out by age 22, but I did not understand the ins and outs of it and rushed in with no protection for amalgam removal, plus I didn't think about the alternative materials and possible reactions to them...sometimes it's best to do testing beforehand. I don't know how accurate the testing is, but in hindsight, I'd do it anyway.

You'll learn a lot here on the amalgam forum!
