Yes they do. Plaque buildup leads to gingivitis and cavities. It is in one’s best interest to reduce plaque not because it makes your teeth look good, but because it will help you not have receding gums when you are older which leads to exposed roots, root canals, tooth replacements, etc…
Electric toothbrushes are simply superior in terms of dental hygiene, no matter how well you think you brush.
But do they lead to better outcomes ? My teeth being extra clean is irrelevant to me if I don’t get cavities either way.
Which, afaik, can be prevented by “simply” not eating anything with added sugar. (Not so simple these days unless you cook everything yourself)
