Philips’ motion-tracking smart toothbrush uses AI to make you a better brusher

The AI in your toothbrush now automatically adjusts its intensity to correct your technique, making over-brushing a problem of the past.

Philips has launched its Next-Generation DiamondClean 9900 Prestige smart toothbrush in Europe and the US, with a global release planned for 2027. This new model, priced at $379.99, is cheaper than Dyson's $499 CameraJet. The toothbrush features a touchscreen with eight cleaning modes and three intensity levels, and a 12-segment mouth map that visually indicates brushing effectiveness. It also includes a color-changing light ring and a third-generation AI model with Philips' SenseIQ technology. This AI monitors brushing pressure and automatically adjusts vibration intensity to ensure safe and effective cleaning, guiding users to improve their technique.

The integration of AI and sensors in oral hygiene devices signifies a move towards proactive health management, where technology actively intervenes to correct user behavior rather than just passively tracking it. Philips' SenseIQ technology aims to provide real-time feedback and adaptive adjustments, distinguishing it from simpler smart toothbrushes that merely log brushing data. This advancement suggests a broader trend in personal care devices that prioritize personalized, corrective guidance.

This launch positions Philips to capture a segment of the market interested in advanced health monitoring and personalized feedback, potentially setting a new standard for smart toothbrushes. The inclusion of AI-driven adaptive features could pressure competitors to develop similar capabilities, shifting the competitive landscape from data logging to active intervention and user coaching in the smart oral care sector.
