Welcome to the Playroom.
Games and small diversions for kids — and, we’ll admit, for grown-ups. They all play with the same idea as the rest of this site: the mouth is a gate, and what happens there doesn’t stay there. Nothing to install, nothing to sign into, nothing tracked: scores live on your device and nowhere else. We keep adding to this room — check back between visits.
Plaque Patrol
You’re the toothbrush. Sweep the bacteria up before they slip past into the bloodstream. Watch for the golden amoeba — it’s the one from our microscope footage, and it runs from you.
Plaque Invaders
Every day, bacteria descend on the gumline and organize into biofilm. You have a water flosser. Fresh plaque wipes right off — what you leave alone links up, shields itself, and calcifies into tartar no jet of water removes. Between days, honest questions about your real routine earn upgrades.
These are games, not medical advice. The facts inside them come from the same research pages as the rest of this site — start with the ten connections or how we test for the bacteria themselves.
