OK, everybody. It's time to brush your teeth. Go get your toothbrush!

Brush, brushy-brush, brushy-brush, brush.
Brush, brushy-brush, brushy-brush, brush.
Brushy-brush, you're looking good.

Brush, brushy-brush.

Brushy brush them round and round.

Brush, brushy-brush.

To keep teeth happy, here's the truth.
You gotta brush each and every tooth.
The teeth in the front get a lot of care.
But don't forget the ones back there.
Brush your teeth, keep them looking clean and bright.

Brush, brushy-brush. Bru-bru-brush, brush.
Brush your teeth, every day and every night.
Brush, brushy-brush, bru-bru-brush, brush.

Now your toothpaste might taste good when you got it in your mouth.
But you should never swallow it.
You've got, got, got to spit it out.
Go on and spit.
We'll wait for it.

Brush your teeth, keep them looking clean and bright.

Brush, brushy-brush, bru-bru-brush, brush.

Brush your teeth, every day and every night.

Brush, brushy-brush, bru-bru-brush, brush.

Now if your parents heard, here's what you've gotta do--
let them have your toothbrush so that they can brushy brush your teeth.

Great job, you're almost done.
Five, four, three, two, one.
Now spit!
