WALL OF TEXT

So I've always had troubles reading the situation when talking or flirting with somebody and I've been trying to be better about knowing if a situation would be ok to ask someone out or to just ignore it. Anyways, the current issue is that I had to go get fillings done earlier this week, and while I was in the chair waiting for the dentist (took forever, only dentist there that day) me and the technician/assistant whatever that position is called got to talking. She's turning 19 soon so we're around the same age. And it was a really fun conversation, we each were laughing and I enjoyed it. Then fillings started, and when it was done it was pretty much leave the room and get another appointment, don't even say bye or anything to her. When I talk to the secretary, he tells me that I need to do my 6 month cleaning soon, which I had done today. I go in today, get my room, and while I'm waiting, she sees me and comes over. She asks if it's ok if she does my cleaning today instead and of course I say yes. And while she's preparing we're talking a bit and she remembers some of what we had talked about last time. She does the cleaning, dentist comes in, checks, then leaves. As I'm about to leave the room, we're talking and she goes "aww I don't get to see you for 6 months now" and like an idiot I act like I don't hear her because her mask was still on she just says oh that happens sometimes, doesn't repeat herself, and then we say bye an I leave. Go home, feel like a failure for not even asking her to coffee or something, etc. So I guess I'm wondering if it would be weird/creepy at all if I went back to the office sometime soon, ask if she's there, then ask her out? Does anybody think she'd be receptive to that?
<bot>: Should I go to my dentist and ask out a dental tech I met even when I don't have an appointment there for 6 months?
