How the tech differs
Sonicare and Oral-B: A fair comparison
Sonic vs oscillating-rotating: understand the tech, the tradeoffs, and which fits your needs.
Understanding Sonic vs Oscillating-Rotating
Sonic Technology
Sonic cleaning uses ultrasonic vibrations at 30,000+ cycles per minute to disrupt plaque biofilm. The high-frequency motion is excellent for targeted, deep cleaning and works well with a wide variety of brush head designs.
Oscillating-Rotating Technology
Oscillating-rotating uses rapid back-and-forth and rotation (8,000–12,000 oscillations per minute) for mechanical scrubbing. This motion is gentler on delicate gum tissue and provides excellent cleaning across multiple modes.
Both excel at cleaning. Here's where they differ.
Sonic advantages
- •Wide variety of replacement brush heads
- •Excellent for deep cleaning and plaque removal
- •Quieter operation than oscillating-rotating
- •Strong smartphone app integration on premium models
Sonic tradeoffs
- •Fewer cleaning modes on budget/mid-range models
- •Higher entry price for quality models
Oscillating-rotating advantages
- •More cleaning modes across all price tiers
- •Excellent budget-friendly options with solid features
- •BrushSync technology on higher models
- •Gentler on sensitive gums (oscillating-rotating motion)
Oscillating-rotating tradeoffs
- •Slightly louder operation
- •Fewer app integrations on most models
