Did you know that there is a difference between battery-powered and electric toothbrushes? While a battery-powered toothbrush is little more than a glorified manual brush, an electric brush has definite advantages over its low-tech counterparts. Electric toothbrushes clean teeth better while keeping you from brushing too hard, are good for people with dexterity problems, and are greener.
Electric vs battery-powered: an arbitrary difference
Technically of course, the difference is rather arbitrary, since both types of toothbrushes use some form of electricity and some form of battery, but a picture should make things clear.
Unlike a battery-powered toothbrush, electric brushes need to be plugged in to recharge. The rules still apply for brushing when you use an electric toothbrush though. Use it twice a day for two-minutes each time. While battery-operated toothbrushes vibrate just a little, the electric models have different programs that oscillate and rotate. Some include sonic cleaning technology, and they may also include programs for sensitive teeth and gum health.
Electric toothbrush advantages
Most of the programs on an electric toothbrushes are timed, ensuring you are brushing long enough. Some electric brushes will not work if you apply too much pressure with them, preventing you from damaging your enamel by brushing too hard. While an electric toothbrush may cost more upfront, you need to replace the head only every six months, which could provide overall savings compared to replacing disposable toothbrushes.
