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 article states there’s no research for it. Doesn’t mean it doesn’t work. But of course it also doesn’t mean it actually works. Everyone may do with that what they will. But it’s hard to argue the logic that flossing helps. You can leave bits of food in your gums for bacteria to eat and produce byproducts that degrade your enamel. Or you can remove that food.
But the fact is that there isn’t much research is indeed a valid concern, especially when the health/science community tries to say something is good or bad. They need to prove it.
