The foundation of oral care is dental floss!

To be honest, I only started using dental floss recently.

I'm so embarrassed ㅠㅠ I thought just brushing my teeth hard would be enough.

I have to floss to get clean.

I was searching online and found out that Oral-B dental floss is famous, so I bought some to try.

The dental floss seems a bit thick. There are teeth where it fits well, and

There is a tooth that won't go in.

I'm going to try my best to write well.
