I think dental floss is really good.

I didn't use dental floss before, but I started using it early this year, and I think it's really good.

It is dental floss with a handle for children.

Since the kids started using dental floss early this year

I have never been to the dentist because of a decayed tooth. Before that, I used to go often for treatment, though.

You should definitely try it. It's good.
