Healthy gums don’t bleed, and are not painful to floss at all.
I’m in my 30s and only recently learned flossing technique and got my gums healthy. Flossing used to take so long and always involved a lot of bleeding no matter how delicate I was.
These days I’m absolute savage with floss and interdental brushes and never have any blood or pain.
Once you get your gums healthy you’ll be disgusted at yourself for ever not flossing. The amount of disgusting I can floss out on an almost daily basis is insane.
Plus you’re breath will not smell gross anymore.
It’s worth committing to the habit of flossing. Trust me.
I’ve heard that they can push things under your gums, and should actually be avoided. Not sure how accurate that is, though.
My teeth were tight too. Broke even the thinnest floss but keep trying. Eventually it became easier - broke s lot too. We use those little Plackers flossers and floss while watching TV or watching birds.
