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

The saying goes that you only need to floss the teeth you want to keep.
If you think about it, a toothbrush will only clean 3 sides of a tooth. Top, outer side, inner side. Not the 2 sides facing neighbour teeth.
How on earth is it very important to clean those 3 sides but not the remaining 2? That just doesn’t make sense. If you think flossing is not useful, to be coherent, you must believe toothbrushing is not useful.
On the flip side, learn how to do flossing right to not hurt your gums. The floss must follow the shape of the tooth, and not be straight. (Ie. move along a U path.) Flossing in a straight line does more harm then good.
