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.
The best 3D printer we know of is biology. Until we can grow a new tooth from some science broth, prevention is imperative. Even once we do, it’ll take a while to catch up to nature.
That and for the price to come down to where mere mortals and/or folks with decent dental insurance can afford it!
