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.
It was the flat one he used, and yes I’ve tries with the Oral B Satin too. Apart from not working for me, it doesn’t seem to be able to do much cleaning even if it did.
I flush or rinse whatever it’s called instead. That works fine for me.
