치실 사용하는 게 좋다고 치과에서 권하더군요
I found it difficult to cut and use dental floss.
So I use disposable dental floss sold at Daiso.
It's affordable and easy to use.
It contains 25 pieces, so even if you use it every day, it will last for a while.
You need to brush your teeth and use dental floss to feel refreshed
You absolutely must use this, especially on days when you eat meat.
