I dream of my mom removing her wisdom teeth in front of me?

In my dream, i wanted to remove my wisdom teeth (this is a reflection of reality) but too scared to. My mom then show me how she remove her wisdom teeth by herself. (this is odd because she's not supposed to have any left but i ignore this in my dream). She was bleeding afterward but she seem cool and collected about it. As for me i was extremely worry that she might get an infection so I nag her to go see a dentist. We arrived at a female dentist office and i commented that she's not our family dentist. But she was a middle age woman and she made my worry/fear at the moment disappear. They helped my mom with the bleeding and remove another of her wisdom teeth. Then they turn over and ask me if wanted to remove mine. But then I was too scare and just said that i want to clean my teeth instead. I walk over to the counter to talk about method of payments and there was a male dentist there. He did not seem to understand what i'm talking about and i just gave up. That's when I woke up. This dream was long and when i woke up, i was 2 hours later than the time i usually wake up. Can anyone explain to me what this dream mean? I tried to look up teeth dream but most is about removing own teeth, except for the one about death. I'm very worry now about my mother, please help
