치간칫솔은 사이즈가 다양해서 좋아요 ㅎㅎ
These days, brushing alone isn't enough for oral care.
Many of you use interdental brushes and dental floss in addition to your regular brushes, right?
If my teeth are close together, I'm not sure if flossing alone is enough.
I have to use an interdental brush to clean it properly.
Interdental brushes come in various sizes, so I should use the one that fits.
