How They Work Differently
Oral-B and Sonicare use fundamentally different cleaning technologies. Understanding this is key to choosing the right brush for you.
Oral-B — Oscillating-Rotating Technology
Oral-B brushes use a small round head that oscillates (spins back and forth) and rotates at high speed. This mechanical action physically surrounds each tooth to scrub plaque away. Multiple clinical studies show oscillating-rotating technology removes more plaque than sonic technology in head-to-head comparisons.
Sonicare — Sonic Technology
Sonicare brushes use high-frequency vibrations (up to 62,000 strokes per minute) to create hydrodynamic cleaning action — the vibrations drive fluid and toothpaste between teeth and below the gumline. This makes Sonicare particularly effective at cleaning between teeth without physically reaching there.
💡 Bottom line: Oral-B is generally better for plaque removal. Sonicare is generally better for gum health and sensitivity. Both are significantly better than manual brushing.
