My dentist in the US said to me that they would actually prefer people to brush less and floss more. They made a point of saying that if you brush twice a day and don't floss at all, they would instead prefer you to brush once a day and completely replace the other brushing session with flossing. (The ideal is brush AND floss every session, but they've learned that just telling people to do that results in them not actually changing anything)
I honestly don't know how good of advice that is, but I brush and floss daily, so it wasn't really directed at me in the first place, hah.
I gave up flossing. It has made no difference as far as I can tell, and my dentist hasn't noticed. As far as I know, research has been ambiguous on the benefits and it's been dropped as a recommendation by some organisations because of the lack of evidence.
The change that did make a difference to me, and is supported by evidence: switch to an electric toothbrush.
Might depend on what you eat but when I first started flossing, the gunk that I saw being removed was enough to convince me that flossing was a good idea.
It may depend a lot on the tightness between your teeth, for example, how beneficial it is?
It surely depends on how your teeth are aligned. Without flossing if I eat red meat for example every single time some get stuck and brushing never gets it out. My wife with the same meal never ever had this problem (or did any flossing btw)
