There is a difference between what I was talking about and what these studies are talking about. They are studying the actual effects on users. Because electric toothbrushes are able to clean teeth more quickly and with less effort people generally have better outcomes with them overall. What I was pointing out is that this is not the same thing as a "better brush". Clean teeth are clean teeth. Doesn't matter how you get there, and a manual brush is perfectly capable of cleaning your teeth. It's just that your supposed to actually brush for 2 whole minutes and use the proper technique which most people don't do. An electric brush compensates for this which is what the improvements seen in those studies is showing. This is what I meant by the common misconception. People see that generally electric toothbrushes cause better outcomes and assume the overall ability to clean must be better, but if used properly a manual toothbrush gets the job done too.
