The Smilen Adventure Game
The Tooth Kingdom — The Brushing Adventure Game Built for Kids
15 regions. 75+ Cavity Critters. One mission — brush your way to Enamel City. The Tooth Kingdom is the built-in adventure game that makes kids run to the bathroom every morning and night.
The Game Inside The Device
Where Every Brush Moves the Story Forward
The Tooth Kingdom is a full adventure game built into every Smilen device. Unlike a brushing timer or a rewards app, the gameplay mechanic IS the brushing. Kids don't play then brush — they brush to play. Every 2-minute session moves them one space forward through a story-driven world they genuinely care about completing.
Pre-loaded on every Smilen device — ready from day one
The World
15 Regions. One Mission. Endless Motivation.
From Fresh Farms to Crystal Caverns, through Cavity Caves and Wisdom Woods — every region is a new world waiting to be cleaned. The entire map is visible from day one. Kids can see exactly where they are, how far they've come, and where they're headed. Enamel City shines in the distance as the ultimate destination — always visible, always calling.
All 15 regions — visible from day one
The Brushing Loop
The Game That Makes Brushing the Point
Every brushing session is a step forward. Gary guides your child through every zone while the Tooth Kingdom adventure plays out live on screen. Kids can't skip ahead. The only way forward is through.
Brush to Advance
Each dentist-timed session moves your child 1 space forward on the region board. Front teeth, back teeth, tongue, floss — Gary guides every zone.
Catch a Cavity Critter
Finish the brushing session and a Cavity Critter appears for your child to catch and add to their Critter Album. With 75+ to collect, they never know which one is next — so they stay for the whole brush to find out.
Complete a Region
The island lights up on the map, Gary throws his biggest celebration, and the next region unlocks. 15 regions stand between them and Enamel City.
Every session is dentist-timed and technique-guided. The adventure doesn't progress until they've brushed correctly — front, back, tongue, and floss. Fun for them. Peace of mind for you.
The Collection
75+ Cavity Critters. Every One Waiting to Be Caught.
Cavity Critters are the mischievous creatures that have overrun the Tooth Kingdom — and your kid is the only one who can catch them. They appear at the end of every completed brush. With 75+ Critters to collect, every session brings the chance of catching one your child hasn't seen yet — and that's what keeps them brushing the full two minutes.

Gary Never Asks Them to Brush. He Just Makes Them Want To.
Gary is our fluffy blue monster on a mission — and he needs your kid's help cleaning the Tooth Kingdom. He guides every brushing zone, cheers every Cavity Critter caught, and throws his biggest celebration when a region is complete. Gary celebrates as your child progresses through the kingdom therefore building their habit. Catch a Legendary Critter? Gary goes absolutely wild.
"Kids don't brush because they have to. They brush because Gary is waiting for them."
