Night of the Inanimate Dentist

As a person with fillings in nearly all of my teeth despite all efforts to prevent it, I am looking for something better then a ******* toothbrush, and more fun and convenient too. I was wondering if it would be feasible to have some kind of continuous tooth care device that you could wear at night or at home while relaxing.

It would be a plastic crescent-shaped thingy that would fit over the teeth and form a wet seal with the gum line. Once on, tubes leading out of the device would suction the thing gently onto the teeth. At that point, water would surf a tube out of a tank into the toothy thingy and then drain out through another tube. Toothpaste, mouthwash, and other good schtuff like that could be sent in and out of it. Little roto-brush head thingies would clean your teeth. This wouldn't necessarily preclude brushing or remove the need for flossing, but it might do something.

Come to think of it, this reminds me of one of the codpiece ideas...
