i don't know, because i don't know enough about how much bisphenol-A it takes to cause reactions or health issues. but, here is more info for you on the subject:
What does it mean? This is the second series of experiments to demonstrate that very low doses of bisphenol A cause chromosome errors during cell division in the formation of mouse eggs. The first showed that eggs exposed in adult females become aneuploid, i.e., that the effect is from one generation to the next. The results presented in this study by Susiarjo et al. show a second generation effect: chromosomal aberrations in the eggs of daughters exposed in the womb, leading to chromosomally abnormal grandchildren. The two effects are mediated by different mechanisms.
one thing i do know is that there is always concern when something toxic is placed close to the brain and fillings are very close, especially if the product likes to go to the brain and remain there.
