This is a toothbrush.

I think I need to come up with a picture book for my patients. It would go like this:
This is a toothbrush. (insert picture of toothbrush)
This is a mouth. (insert picture of mouth)
This is where you stick the toothbrush. (insert picture of toothbrush in mouth)
No silly, you want to use the end with the bristles! (insert picture of toothbrush with handle end in mouth. Person looks confused. Insert picture of toothbrush with bristle end in mouth. Person smiles and looks confident.)
This is how you use the brush. (Insert a moving picture, like in the Cracker Jack box, where brush moves back and forth)
This is floss. (Picture of floss)
This is how you use it. You should use it more than every 3 months when you see me. It's beyond gross that you have had food sitting there since then. It's rotting & fermenting between your teeth. (Insert picture of rotting food that appears to smell very badly.)
You should be able to keep your own teeth clean for 3 months. There is no reason for you to need to see me on a monthly basis. (Insert picture of me, looking sad, mad and grossed out all at once)
(Insert picture of monkey brushing his teeth.) If he can do it, you can too.
