Electric toothbrushes ensure cleaner, whiter teeth and fresher breath. The heads of these electric-driven toothbrushes move close to 7000 times every minute to scrub off bacteria and plaque from the deepest corners of the mouth and reduce gingivitis. The heads are generally independent of the handle. So, instead of having to ensure that your toothbrush bristles reach every nook, you can just move the handle inside your mouth. The rotating heads take care of the cleaning.
The concept of using electricity to power toothbrushes is not a recent development. Way back in the late 1800s Dr Scott, an American, invented what he called an electric toothbrush. This electric toothbrush, unlike today, did not function powered by electricity but merely sent an electric current through the brush. This was supposed to promote good health. It was only in 1960 that the first rotational toothbrush, Broxodent, was introduced.
Electric toothbrushes were first used by people with arthritis dexterity problems and the elderly, but became more popular as they started addressing the specific needs of various users. The bristle types are generally: very soft, soft, medium, hard, and very hard. While soft bristles are meant for children and people with weaker gums, hard bristles are meant for adults. For best results you are advised to use fluoride toothpaste.
Since the brush heads are detachable and replaceable, an electric toothbrush can be used by various members in the family. All you need to do is buy the various bristle types. Since many users tend to apply excessive pressure while brushing teeth, increasingly manufacturers are introducing pressure sensors in electric toothbrushes which ensure the toothbrushes stop if brushed too hard. The brush heads have varied movements such as rotate, side-to-side and vibrate. Brush heads deteriorate over time so, once the bristles begin to curl, they should be replaced. This could be two to three times a year.
These devices are generally cordless and use rechargeable batteries. Many also come with built-in timers, which give users an idea of how long they should brush their teeth. Generally, users are recommended to use electric toothbrushes for 2.5 to 3 minutes.
Brushing can definitely be a lot more fun with the electric toothbrush (especially for children) hence subconsciously people tend to brush longer and this ensures teeth are cleaned thoroughly.
