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.
