I was a big skeptic regarding electric brushes. Until I used one. It does
clean a whole lot better. Also, since then the dentist doesn't find any
serious mineral buildups near the gum line anymore.
A long time ago we had a brainstorm session at a med ultrasound company,
to come up with product ideas. The sky was the limit. So we gathered in
little groups and ours had on its list, you guessed it, an ultrasonic
toothbrush. Laughing was prohibited but the guys were rolling on the floor
holding their bellies. Needless to say we left the stage like wet dogs. A
few years later Philips built one and still makes oodles of money. We
could all be on our own islands now :-(
You must be talking about consumer products - some decades ago, I had
a cleaning and they had an ultrasonic scraper thingie, but this was
used by the pros - and from the way it sounded and felt, it wouldn't
have gone over well as a consumer product.
So, how does the ultrasonic toothbrush work? Is it like a little nylon
chipping hammer? ;-)
I have an idea for a turbo paint scraper; the Kirby patent on the
turbo-brush should have expired by now...
Cheers!
