I also chose flossing. I floss every day and it feels good; it’s satisfying in a way that brushing isn’t. I could go without brushing for three days, bu it would drive me INSANE to have gunk stuck between my teeth that I couldn’t remove.
I almost never flossed, until one of my teeth moved weirdly, and left a funny gap between it and the one next to it. Now stuff gets stuck there. I use toothpicks, floss, and a waterpik on it. And it drives me nuts if I don’t have one of those tools handy.
So I’m going to guess that different people have objectively different experiences with flossing.
That said, I’ll go without flossing, and use toothpicks for those three days. I hate flossing.
I’ve 3 places where big pieces of food can get stuck between my teeth, and brushing alone doesn’t always remove them. I’d either have to give up brushing, or be very careful what I ate.
