Clean teeth
Germs have landed on crumbs of sugar! Brush the teeth to and fro before they leave stains.
Clean! The brush sweeps the germs off with the crumbs.
Oh, here the germs left a stain of acid. Brush faster!
More germs! Do not forget any tooth.
Germs eat sugar and make acid that wears teeth away. Brush your teeth twice a day for 2 minutes.
