Tests personal-care devices on fixed protocols, with results cross-checked by a dental hygienist.
Our top pick is the Oral-B iO Series 9 (~$250). The cleanest plaque scores in our hygienist's check and the best real-time pressure feedback of anything tested.
After analyzing multiple sources, this is what we found.
I used seven electric toothbrushes for a month each (rotating to avoid bias) and had a dental hygienist score plaque disclosure before and after.
The gap between a $40 brush and a $300 brush is real but small. What matters most is a pressure sensor, a two-minute timer, and that you actually use it.
Scoring weighted cleaning per the hygienist's plaque scores (40%), pressure sensor and feedback (20%), battery and travel (20%), and brush-head cost over two years (20%).

Oral-B iO Series 9
~$250The cleanest plaque scores in our hygienist's check and the best real-time pressure feedback of anything tested. It is pricey and the heads are not cheap, but if you want the most effective brush, this is it.
Bitvae D2
~$35Genuinely surprising for $35. Sonic cleaning, a real timer, and a battery that lasts weeks. No app and a less premium feel, but the hygienist could barely tell the plaque results apart from brushes ten times the price.
Philips Sonicare 9900 Prestige
~$280The most comfortable brush for sensitive gums, with the gentlest effective mode of the group. Cleaning is a touch behind the Oral-B, but if aggressive brushing has been your problem, this is the safer pick.
