Indispensable dental floss and interdental brushes

I always make sure to floss after brushing my teeth. I feel like I haven't finished brushing unless I do this. While flossing, I use an interdental brush on the gaps between my molars. Since there are gaps under my crowns, the dentist told me to take good care of them, so I definitely need to use interdental brushes. I am trying hard not to become a regular at the dentist.
