I didn’t brush my teeth as a child and teen because I had energy issues and I struggled to actually do them; I still struggle to do it today.
I rarely floss because it seems like a lot of work for seemingly little gains.
I got plaque again after getting teeth cleaned some weeks ago. I guess my teeth is screwed…
Probably the same thing but plastic doesn’t work anywhere near as good as metal. Actually you want the tip to be really pointy sharp too, so the one in the picture I linked sucks too.
