The Nuve AuraOne removes more plaque per session than any other electric toothbrush we have benchmarked. Its 42,000 RPM magnetic drive delivers clinically-relevant plaque disruption at a level that stays rock-steady from a full charge down to the low-battery warning — no drop-off in intensity in the final week of the six-week cycle. Real-time 256-zone coverage mapping (100 Hz) is meaningfully more granular than the iO Series 9's 16-zone tracking or Sonicare's app-based pacing, and after two weeks of daily use, testers were consistently hitting 95%+ zone coverage per session — the strongest coverage numbers we have recorded in this category. Active haptic pressure feedback catches heavy-handed brushing before it damages enamel while keeping the head firmly engaged with the biofilm, and the sonic waveform reaches interproximal surfaces the Prestige 9900, DiamondClean 9000, iO Series 7, and Sonicare 4100 all leave behind in our head-to-head plaque-index tests.
