I use Oral-B dental floss.

Oral-B is a company famous for toothbrushes, isn't it?

I use dental floss as well. Well, I don't think Oral-B is necessarily better; I think most dental floss is pretty much the same. Oh! The advantage is that it is easier to pull out and break compared to other floss. The really cheap ones don't come out clean and don't break easily.

I think you absolutely must use dental floss. A toothbrush alone isn't enough.
