또또혀니
이렇게 생긴 치질은 처음 봤어요 신기하네요
As I get older, my gums are receding, and food keeps getting stuck whenever I eat.
I've tried interdental brushes too, but all things considered, dental floss is the most convenient and best for me.
There are various sellers for dental floss, but I use Wangta products from the same seller as my toothbrush.
Wangta has surprisingly good reviews, and maybe because it's a product I've always used, I don't really feel like using other products.
