I cover this topic to some extent here
The number of
chemicals in a composite filling is pretty large and many are known to
be toxic to some degree. BPA
is used directly in the manufacturing of some resins, it is also a byproduct
of chemical degradation of resin-based dental materials, and residual
amounts can be found in nearly all composites from incomplete chemical
reactions. (reference) Composites also have been proven to result in higher levels of BPA in
the urine (for how long is unknown) no matter how they are applied (a
protective rubber dam has 0 influence on amount of BPA leaked into your
system). BPA in the urine does mean the body is eliminating it, but how much of it? reference
There are several studies showing effects like prenatal exposure to BPA being tied to hyperactivity and anxiety, especially in girls. Newer studies are showing effects on behavior.
