그렇군요, 정보 감사합니다
I always brush my teeth after meals, but I use dental floss once a day to completely remove the food particles stuck between my teeth.
Since it's a double line, it seems sturdier and more effective than the single-line floss. I do use the other end occasionally, but I keep bleeding, so I don't really like it. It isn't uniformly thin and long like a toothpick; instead, it has a pointed tip that thickens quickly, so I find it difficult to use.
