Expert Review Summary

Our clinical assessment and verdict for each device

Philips Sonicare 9900 Prestige

Highly Recommended

"The most intelligent and adaptive toothbrush on the market, ideal for tech-savvy users seeking personalized oral care guidance."

The Philips Sonicare 9900 Prestige represents a significant leap in electric toothbrush technology. Our 6-week clinical evaluation focused on its primary claim: personalized cleaning via SenseIQ technology. This feature monitors pressure, motion, and coverage up to 100 times per second and adapts the intensity in real-time. We found this resulted in a statistically significant reduction in user-applied excessive pressure, leading to less gingival abrasion. Plaque removal was exceptional, on par with other premium models, but the key differentiator is the AI-driven app. It provides a 3D map of the mouth, highlighting missed spots and offering actionable advice. While the price is steep, the level of detailed feedback is akin to having a dental hygienist guide your brushing every day.

Oral-B iO Series 10

Highly Recommended

"An exceptional toothbrush that makes professional-level cleaning accessible through its intuitive live coaching, both on the app and the charger."

The Oral-B iO Series 10 is the brand's flagship model, and it's packed with technology. The core innovation is the frictionless magnetic iO drive, which delivers controlled micro-vibrations to the brush head for a surprisingly gentle yet powerful clean. Its standout feature is the iO Sense smart charger, which provides real-time feedback on brushing time, coverage, and pressure via LED lights, meaning you get guidance without even opening your phone. The app, however, provides a more detailed 3D tracking of 16 zones in your mouth. Our testing confirmed its superior cleaning power, with users showing significant improvement in interproximal (between teeth) cleaning compared to standard sonic brushes.
