Make Brushing Fun Again

The Colgate Hum Kids smart toothbrush turns brushing into a fun, educational experience. Paired with a mobile app, it uses gamification and real-time feedback to improve children’s brushing habits, while a parent dashboard tracks patterns and highlights missed spots.

Changing Daily Habits

Most kids don’t brush effectively or consistently, and existing solutions focus on reminders rather than behavior change—leading to low engagement and weak long-term habits. At the same time, parents lack clear insight into how well their children are actually brushing, creating an opportunity to design a connected experience that teaches technique, builds habit, and adds accountability without feeling clinical or forced.

Level Up as You Brush

I shifted brushing from obligation to motivation by designing around behavior:

Made it rewarding → Turn progress into visible, immediate feedback

Designed for autonomy → Let kids feel in control, not instructed

Supported the parent → Provide insight without adding friction

Bridged physical + digital → Connect real-world behavior with in-app feedback
