저는 치실만 사용하는데 치간칫솔도 사용해야겠어요
As I get older, the gaps between my gums have widened, so it seems like brushing alone isn't enough to remove food particles anymore.
If I don't use an interdental brush, it feels uncomfortable, like I haven't brushed my teeth at all.
I prefer one with a moderate thickness rather than being too thin.
