Edit: Since it’s come up a couple times in the comment, I’ll add that there’s evidence use of a water flosser is more effective than dental floss.

I mean, as they kind of point out in the article, this doesn’t actually say terribly much. I’ve always had the impression that electric toothbrushes are great for scrubbing off the plaque on the big surfaces of your teeth, while they’re probably worse at reaching all the weird little angles of your teeth. This could result in 20% less plaque in total, while not removing it from where it lingers around and causes cavities. At the same time, if you also floss regularly, maybe you’ve got your weird little angles covered differently already. It depends on quite a few factors, for which a meta study like this can hardly do justice…
I mean it also shows a 6–11% reduction in gingivitis, so it’s at least getting some of those weird little angles better. Gingivitis most commonly occurs because plaque stays too long around the lining of the gums, and thus electric brushes should at least be more effectively getting this off the bases of the crown – which to me were always way more difficult and awkward to effectively treat with a manual brush.
Meanwhile, there’s really no such thing as using your toothbrush as a substitute for proper interdental cleaning, and that’s why your dentist really will notice if you haven’t been flossing properly. A water flosser is best for something like that.
