Electric Toothbrushes full story!
Do

Let's
how people start to use it and when,
Power
Toothbrushes: Electric and Sonic
Electric
toothbrushes were first introduced in the U.S. in 1960 by a company called
Squibb, and marketed under the name Broxodent. Today, there are dozens of
different brands available, with a myriad of features, including re-chargeable
batteries, compact designs, and bristles built for optimal cleaning.
The
two main types of power toothbrushes are electric and sonic -- the difference
between the two really comes down to numbers.
Electric
Toothbrushes: With 3,000 to 7,500 rotating motions a minute, electric
toothbrushes are powered to replicate the motion of your hand -- doing the
muscle work for you. The bristles on these toothbrushes either rotate or move
back and forth to help remove plaque and reduce gingivitis.
Sonic
Toothbrushes: Offering 30,000 to 40,000 strokes per minute, sonic toothbrushes
rotate in a back and forth vibrating motion. The rapid motion is the sonic
toothbrushes' claim to fame. But ultimately, it also aims to remove plaque and
keep teeth and gums healthy and clean.
For
a little bit of perspective, the old-fashioned way of brushing your teeth rings
in about 300 strokes per minute -- if you brush properly. So over the
two-minute recommended brushing time, your teeth are hit with 600 strokes … a
far cry form the thousands you might get with the high-tech variety.
