Training kids brush their teeth hardly.
When children stand front a mirror to brush their teeth,
they will see some different colors which is from yellow to white on the toothbrush.
and we want children to compare the colors with their teeth and clean their teeth harder to become white.
It also make some fun when kids clean their own teeth.
