I'm desperate for someone to tell me she's ok. I wore invisalign braces during my whole pg with DD. They are made from a polycarbonate plastic blend is all they will say. The formula is proprietary and they won't even speak with me. They will only speak with a dentist. I'm kicking myself and though she seems healthy, I'm afraid I've damaged her for life. There was this small study done on rats where they fed them BPA containing plastic and as much as 50% of the eggs in their female offspring were messed up. Now I'm afraid that her eggs are damaged, and there's no way to know. I'm afraid that the plastic used was estrogenic because it made my lichen planus flare up again, which used to always be worse on BCPs and during the first half of my menstrual cycle when I wasn't on them. I'm terrified, and want some hope that things are ok. With all the talk here on mothering of changing sippy cups.... if that amount of exposure is a problem, I can't even imagine what I have done.
