Yes, modestly - and the gap grows with use: Cochrane found powered brushes removed 11% more plaque at one to three months, 21% more after three months.
Gingivitis fell 6% and 11% over the same periods, and an 11-year cohort study found powered-brush users kept more of their teeth. The honest caveats: a well-used manual beats a lazy electric, and the biggest gains show up in inconsistent brushers - most of us. The timer and the replaced head matter more than the price tier. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper .
What to do
Common questions
Do electric toothbrushes work better than manual?
Yes, modestly - and the longer you use one, the more the gap shows. The Cochrane review of powered versus manual brushing found powered brushes removed 11% more plaque at one to three months and 21% more after three months, with gingivitis reductions of 6% and 11% over the same periods - evidence rated moderate quality. An 11-year cohort study from the European Federation of Periodontology goes further: powered-brush users kept more of their teeth over time. The honest caveats: a well-used manual brush still beats a poorly used electric one, and the biggest wins show up in people whose technique is inconsistent - most of us. Price range is wide, and you do not need the top of it: the rotating-oscillating or sonic head, a two-minute timer, and replaced heads every three months carry most of the benefit. The brush matters less than the two minutes, twice a day - but the brush helps.
