The Oral-B iO Series 9 is our top overall pick, combining superior cleaning with a smart display and pressure control.

To help you decide, we’ve looked at expert reviews, owner feedback, and published comparisons to rank the top models from each brand. We focused on cleaning efficacy, battery life, smart features, and long-term value. Below is our honest take on the three best contenders for 2026.

Frequently asked questions
What is the fundamental difference between Oral-B and Sonicare?
Oral-B uses oscillating-rotating technology: the round brush head rotates back and forth in short arcs while also pulsating in and out. This mechanical action physically sweeps plaque off tooth surfaces and is the technology most extensively studied in clinical literature. Philips Sonicare uses sonic technology: the brush head vibrates at high frequency in a back-and-forth motion, and the acoustic energy also drives fluid between teeth to disrupt plaque beyond where bristles reach. Both are more effective than manual brushing; the difference in clinical outcomes between the two is small and depends on technique as much as technology.
Which brand has cheaper replacement brush heads?
Oral-B compatible brush heads are generally cheaper and more widely available than Sonicare heads, both in official replacements and third-party compatible options. The round oscillating head design has been standardized across Oral-B handles for years, creating a large ecosystem of compatible heads at varying price points. Sonicare heads are more proprietary, compatibility depends on which brush head series your handle supports, and the range of third-party options is narrower. Over three to five years of ownership, brush head costs are a meaningful part of the total cost of ownership, and Oral-B tends to win on that front.
Which brand's app is actually useful?
Both Oral-B and Sonicare offer Bluetooth-connected models with companion apps, and both apps have checkered histories of reliability and usefulness. Oral-B's app, at the premium iO tier, provides real-time brushing feedback through the phone camera, showing which areas of your mouth you've covered and flagging where you've missed. Sonicare's app offers similar zone tracking and coaching. In practice, most users stop opening the app regularly within a few weeks. If app coaching genuinely motivates you to brush better, either works. If you won't use it, the connectivity feature is a cost you're paying for nothing, skip it and spend the savings on a better brush head.
