Regarding the use of dental floss

How do you all use dental floss?

I thought I was only using dental floss for the gap between this and this.

However, I see that you use dental floss in various ways~

I thought flossing was only done back and forth, but there are actually quite a few different ways to use it.

They thought of brushing away plaque by rubbing the tooth surfaces up and down with a back-and-forth motion.

Thorough brushing can prevent oral diseases and is also effective in eliminating bad breath.

I was afraid, so I didn't do it well, but I think I should try once.

I only used the Waterpik, but they say that Waterpik alone cannot fulfill the role of dental floss.
