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.
My teeth are just really tightly togheter… I have absolutely no idea where an interdental brush would even go, it just bends and breaks if I try to push it between my teeth. Even getting the floss in there is already hard.
I also have tightly packed teeth and can barely use interdental brushes on just some of them. What works well however are dental floss sticks, you can get them with pretty thin floss(es?) and they’re way easier to use than plain floss.
