Kevin had just finished dessert. It was a piece of dark chocolate, washed down with a glass of cold milk. Delicious! He rinsed his mouth out with a glass of water, and then spit into the kitchen sink.

He sat down at the dining room table and grabbed some floss. He carefully flossed his top teeth and then his bottom teeth. Flossing was a chore. The floss almost always got stuck between two teeth in the upper back and two teeth in the lower front. Finally finished, he threw the frayed floss into the trash.

He went into the bathroom and grabbed his electric toothbrush. TV ads always show people putting toothpaste onto the entire length of the brush. Of course, that was to get them to use up the tube faster so they’d have to buy another tube sooner. Kevin put just a little toothpaste onto the brush. He brushed for about a minute.

He spent another 30 seconds brushing his tongue. Then he spit out all the toothpaste, and gargled and spit again.

Brushing and flossing are such a pain, he thought. If they can put a man on the moon, why can't they invent something easier and faster than toothpaste and dental floss?
