I clicked just to see. You’re absolutely right.

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.
