There could be nothing more powerful and moving than a public service announcement where a meth addict has all of his teeth fall out. He’s conflicted at first, but then eventually he brings his mind to a state of ease upon the assumption that at the very least he could put the teeth under his pillow. Then, whatever money the tooth fairy leaves, he could use to buy more meth.

It takes him days to fall asleep, but finally he does. He dreams about the tooth fairy, but when he wakes up and looks under his pillow, the teeth are gone and there is no money.

Suddenly, the dog runs into the room and it instantly becomes obvious to the viewer that the dog lapped up all of the teeth shards and somehow, they became arranged in his mouth like people teeth. 

The rest of the story follows the dog around and highlights his various successes.
