Tooth filling - effects on fertility?

Hi folks. After 35 years alive, I have my first ever dental cavity. I am currently trying to conceive and I am so nervous that the filling material (white composite resin) will be toxic to me and my fertility. The cavity is tiny and they've been following it for years, and say that the time has come to fill it. Can ya'll please just ground me in the reality of how bad this might be and how I kind of just HAVE to do it?! Unless you have any other suggestions... TIA. https://www.ncbi.nlm.nih.gov "It has been also shown that both Bis-GMA and TEGDMA have reproductive toxic effects in female mice when they were administreted at doses of 25 and 100 μg/kg intragastrically for 28 days.[74]" /pmc/articles/PMC3532765/
