Maybe. The recommendation for flossing comes from tradition and anecdotes, not good evidence. Flossing isn't evidence based[1], though that doesn't mean it's useless and we shouldn't do it, just because something isn't evidence based doesn't mean it doesn't work.
We probably should floss because it's probably helpful, even if the evidence is weak, it has a plausible mechanism of action, it's low cost, low risk, and teeth feel good after a proper flossing.
A big issue is many people have poor flossing technique though, which is (probably) not great for gums and may actually cause problems. Flossing shouldn't hurt and you should talk to your dental hygienist about proper (recommended) technique. Also have him or her actually floss your teeth if they don't already during a cleaning (mine does) so you can get a feel of what the recommended technique feels like. Also try different types of floss. My hygienist can floss me just fine with the "normal" type floss but I can't replicate that for some reason, I need to use the "glide" type floss.
You'd be surprised, but above is not the commonly accepted truth, and is debated amongst dentists. (research across countries also lends credible data to both sides in the debate).
