u/Anybody-Other

So I just graduated from dental school 6 weeks ago and was hired almost immediately. I feel like I’ve caught on quickly to most of the procedures that my office does, but I’m trying to not be super critical of myself but I feel like I’ve just sucked it up the past two weeks with mistakes like incorrect charting (missing premolars are killing me) and maybe not keeping the Dr.s mirror properly cleaned while assisting. My question is, can an assistant actually make the Dr mess up their work? Like if I don’t keep the mirror cleaned correctly can that make the dr mess up what they are doing or since they’ve been doing this for so long would it take so much more than that to make them mess up?
