I’m related to my dentist and I trust her, and I don’t floss either and she hasn’t commented on it. Maybe some people just don’t need to floss as much? Maybe it’s diet or genetics?

I dunno about genetics but my dentist told me to floss regularly because it's the healthy thing to do. Imagine eating a piece of meat and some of it gets stuck deep in between your teeth and regular brushing isn't enough to remove them and they just rot in your mouth for weeks/months.

Actually to non-flossers reading this I suggest flossing once and smelling the bits of food that you removed and I guarantee you'll change your mind about not flossing lol
