I've been Brushing

 To tune of: I've been working on the Railroad

I've Been brushing with my toothbrush,
Brushing everyday.
I've been Brushing with my toothbrush,
It's how I fight decay.
All my teeth are gonna sparkle
How proud I will be.
Every time I want to smile, my
Teeth will Shine for me!
Always brush your teeth,
Every Single day.
Keep those cavities away!
Use your brush and paste,
Just the way you should,
Keep your smile a looking good!
