How do you floss?

When I first started flossing, I tried to do it with my hands, but

When doing it on the innermost molars, open your mouth too wide.

At that time, I was really worried about my nasolabial folds.

It was too hard to put my hand in

I use a tool to loop and use dental floss.

Sometimes I wonder if this tool is removing food particles properly.

There are times when I wonder if I'm doing well.

I think I could be a bit more meticulous if I did it by hand...

The feeling you get with your hands is very different from using a tool, isn't it?

I'm curious if there are many people who just do it by hand.
