Keep It Clean

Teeth have more than one side! 🪥 Split the outer, inner, and chewing surfaces into upper and lower parts—six spots in all. Brush each spot for 20 seconds, and all six take exactly 2 minutes. Check what gets missed if you brush only the outside. 🍬 Next: sweets. Each time you eat candy, your teeth dissolve for 20 minutes—so the number of «times» matters more than how «much» you eat. Tap to see what happens when you spread it out. 🧼 Finally, handwashing. How much is left behind depends on how many seconds you wash. Tap to see what happens if you don’t wash. This app was made with code too · Remix it to make a toothbrushing timer for your class!
