I remember reading a study from decades ago stating that electric toothbrushes are only more effective if you are a drinker. The impression it gave was that even while drunk the electric actuation made up for sloppily doing your teeth 😅.

I think I've been using an electric toothbrush for so long that I'm not good at using a manual anymore.

I also discovered that I press too hard and the electric toothbrushes that warn me when I apply too much pressure has been helpful in preventing gum recession from over brushing.

My dental health had also been improved by a portable waterpik. I add a little bit of mouth wash to it so the machine doesn't fill with mould. I still floss every time, but the waterpik gets out food I'd never get out otherwise. I struggled with bleeding gums before that.
