오랄ㅂ많이 쓰시더라구요
This is Oral-B waxed floss, which seems like the most useful type of floss available. It is said that brushing misses as much as 40 percent of the surface area of your teeth. You need to floss to remove debris missed by brushing and to eliminate bad breath by removing hidden food particles. The Oral-B waxed floss I use is very thin, so it is suitable for me since I have narrow spaces between my teeth. I recommend trying to floss, at least before going to bed.
