Flossing

The nurse at the dental clinic told me to try using dental floss and explained how to use it in great detail.

Actually, I didn't know much about dental floss until now.

When I first started using dental floss, I struggled a lot because I didn't know how to use it properly.

As I practiced in front of the mirror, I remembered the nurse's advice.

I have many molars filled, so I was told to pull the floss sideways rather than upward.

The dental floss is a Daiso product; it costs 1,000 won, but it is long and comfortable.
