1. Silent, Sleek, Sustainable: Sonicare’s Sonic Technology

Philips Sonicare’s hallmark is its high-frequency 62,000 micro‑vibrations per minute, creating fluid dynamics that reach beyond bristle contact into gum crevices—ideal for sensitive teeth and delicate gums,
- Quieter operation (~60 dB) compared to Oral‑B’s louder oscillations (~72 dB)
- Extended battery life (3–5 weeks per charge) with USB‑C travel cases boosts convenience on the go
2. Power & Precision: Oral‑B’s Oscillating‑Rotating Action

Oral‑B employs oscillating‑rotating and pulsating 3D movements that clinical trials show can deliver up to 48% more plaque removal at the gumline versus manual brushes
- Round, dentist-inspired brush heads allow precise access—ideal for tight spaces, braces, and molars.
- Integrated pressure sensors and timers support effective brushing habits.
3. Clinical Evidence: Minor Differences, Big Impact
- Several independent and manufacturer-sponsored trials favor Oral‑B’s oscillating method for plaque, gingivitis, and bleeding reduction.
- Yet, a 2019 study showed Sonicare’s sonic action led to 56% greater reduction in gingival inflammation in one trial.
Bottom line: Both significantly outperform manual brushing. Oral‑B offers a slight edge; Sonicare excels in gentleness.
