I admit I shamelessly stole the title from a quote from Walter Hinteler.
Anyway, considering that a lot of people, despite years of training in school, scolding by dentists and hygienists, the prospect of expensive dental work and out-and-out fear of teeth being pulled and/or root canal,
still don't brush well or effectively. Hence, a product comes out every now and then which purports to solve the problem. See:

That's a study done on the Braun Oral-B power toothbrush with rotational/oscillation action, comparing it with other power toothbrushes and manual brushing. Like most medical studies, it's inconclusive. Essentially, you do better with this brush if you're not that skilled at brushing your teeth. But if you have average tooth-brushing skills, you should be able to get as good results, or better, than all types of brushes, including this power toothbrush.
Neither my dentist nor my hygienist has recommended this brush. In fact, they
never recommend power toothbrushes - they just hand me a Reach(TM), a rubber-tipped instrument and some toothpaste samples as I leave, and remind me to always use a soft-bristle brush.
Has your dentist and/or hygienist recommended this brush? Have you ever used it? How did you like it? Were your dental cleanings easier or shorter than before you started using it?
