Why does my tooth look like this?
22f I just had this tooth pulled today, it’s a baby tooth that I believe had a cavity filled when I was younger. I’m curious what the black line is and how a little whole was on the other side. I also feel like it’s a weird shape in general and they made a comment that part has dissolved I think? I have no adult tooth and am wondering how long I have to get an implant before my teeth start to shift?
Also the area hurts a lot more than I anticipated and that’s making me think my teeth are moving but I don’t know.
Thank you
