Is it necessary to floss if I use interdental brushes?

Cosimo Q.
Yes because floss reaches part where the brushes won’t. The interdental brushes are good for big gaps at the root of the teeth but not for between. My dental hygienist told me I had to do both!

I'm not really sure what an interdental brush is, but if it's doing the same job as floss, then I don't see why you would have to do both.
