Isn't flossing not supported by science also, but all the news articles said you should keep flossing?

Yes, flossing cannot be proven to help. But it cannot be proven to hurt, either, so current recommendations are to do it anyway.

I still floss because I think its gross and I have bad gaps in some of my teeth, but I think flossing can also cause harms, for example some floss has PFAS in it.
