Crestfallen
You may never need toothpaste again if this catches on:
[T]he Soladey Ionic Toothbrush, from Japan, could provide a solution. Invented by Dr. Yoshinori Nakagawa, this light activated toothbrush contains a titanium ionic conducting rod, which runs through the replaceable bristle head and into the handle. Apparently, the light activated rod, when exposed to any source of light, converts the light into negatively charged ions, which are released into the mouth, blending with saliva to attract positive hydrogen ions from the acid in the dental plaque on your teeth. This acid is then neutralised and plaque is disintegrated. Toothpaste is not necessary because your saliva is the active ingredient. The head is replaceable, so the toothbrush and rod can last you a lifetime (if you look after it properly).
Disclosure: I am a bit leery of anything in which saliva is the active ingredient.
The Soladey sells Stateside for thirty bucks, which is a bit less than I paid for one of those ultrasonic jobs.

Oh, yeah… it’s all fun and games until your jaw falls off or your head explodes…

It could be worse. I’m imagining dental floss with encapsulated oxidizing agents along its length. For all I know, Montana’s Department of Agriculture is already looking into the possibility.

Well? Which is it, then?

Depends on how firmly your jaw is attached.
