오랄비 치실 많이들 사용하시는것 같아요
While looking through various reviews, I found a famous Oral-B dental floss I am currently using [product/service], and there is definitely a difference before and after using dental floss. If you tend to get food stuck in your teeth frequently, it is good to use dental floss or interdental brushes as well.
The product I purchased comes in a form that you break off to use, so it was a bit difficult for a beginner to use. It was hard to floss the back of the molars.
Next time, I want to try using dental floss with a handle to see how it differs.
