BPA can be even more harmful that amalgams!!! Just look at the recent studies on mice that found that mice seemed to be more anxious, have memory issues, and a host of other neurological and even reproductive concerns. The issue lies with BPA interfering with estrogen receptors in the brain, this ends up affecting women more so than men, especially during important stages of development. I've been tested for biocompatibility issues for the composites that I had put in 10 years ago when I was 14. I should have the results next Saturday for my appointment. If the tests prove to be valuable, I'll post about them and suggest them for you too.
