This article introduces BrushO's AI-Powered Mining Toothbrush as a revolutionary personal oral health coach, moving beyond traditional smart toothbrushes. It highlights how BrushO's proprietary Fully Smart Brushing (FSB) technology provides real-time, precise feedback on technique, pressure, and coverage, transforming a daily routine into an intelligent, personalized oral care session. Beyond immediate improvements, the article explains how the AI analyzes long-term habits for proactive prevention and targeted improvements. Crucially, it emphasizes that this AI coach also rewards users through a 'brush-to-earn' model (with $ORAL/$BRUSH tokens) for contributing anonymized data to BrushO's Decentralized Physical Infrastructure Network (DePIN), empowering users with data ownership while contributing to global health insights. BrushO ultimately offers a unique blend of personalized care, tangible rewards, and data sovereignty, setting a new standard for a healthier future.
