Is it good to use dental floss or interdental brushes consistently?

Whenever I go for a scaling, the dentist always recommends using dental floss.

So I'm trying to give it a try every now and then...

I bled a little... and since I wasn't used to using it, after doing it a few times...

I ended up not doing it.

Still, since the dentist keeps recommending it, I think I should do it in the long run.

If you use dental floss or interdental brushes consistently

I'm curious if it definitely helps with dental health.
