Is it time you gave your old toothbrush the brush-off? Electric toothbrushes are available in a range of prices and with features to complement -- or correct -- your brushing behavior. Take our quiz to see how much you know about them.
The three types of toothbrushes available are electric, manual and battery-powered.
Americans brush their teeth for an average 31 to 65 seconds, depending on sex and age.
Dentists recommend brushing your teeth for 2 minutes at least twice per day; not brushing for the correct time is one of the leading causes of poor dental hygiene.
While some electric toothbrushes have specially designed heads that help polish teeth, especially when used with a whitening toothpaste, none spray bleach as you brush. At least not yet.
In a survey of 16,000 patients published by the American Dental Association, more than 80 percent reported that they improved their oral health by switching from a manual toothbrush to an electric toothbrush.
Electric toothbrushes clean more efficiently than manuals within a set timeframe because they produce a higher number of brushstrokes per minute than you can get manually.
People who have mobility problems (due to arthritis, for example) and manual dexterity issues typically find it easier to use an electric toothbrush. The handle is larger, making it easier to grip, and its whirring motion means people don't have to move their hands and arms as much.
Most dentists recommend changing your electric toothbrush head every three to six months, or as soon as you notice the bristles becoming misshapen.
Worn bristles lose more than 80 percent of their cleaning ability. That's why it's important to replace your toothbrush regularly.
Electric toothbrushes can run anywhere from about $20 to more than $100. How much you actually choose to spend depends on your budget.
