Introduction to the Electric Toothbrush

introduction electric toothbrushThe evolution of the humble electric toothbrush is a fascinating story. Developed nearly a century and a half ago as a tool for handicapped individuals, the electric toothbrush has been developed into a highly sophisticated gadget, at least that’s what the marketing brochures want you to think.

When it comes down to it, the electric toothbrush is a rather simple device. They are powered by batteries and work by vibrating and oscillating the brush head that resides on the tip. Some of these brushes actually move in rotating circular motions while oscillating, others are able to have their bristles rotate in different directions at the same time, and there are ones that use ultra-sonic vibration, or ultra-sonic vibration along with oscillation. Sonic toothbrushes that vibrate over 30,000 brush strokes a minute are currently at the frontier of tooth brushing technology.

The movements of the electric toothbrush head are the result of electric charge that comes from the battery inside the brush. The toothbrush head is one of two main parts of the electric brush and is usually removable. The good thing about removable heads is that a few people in the house can share one electric toothbrush. All they need to do is to buy and make sure that they use different toothbrush heads.

The electronic base of the toothbrush is housed in the outer case. This base is comprised of a circuit board, a motor, gears, cam and battery. The outer case also houses the on/off switch which sometimes doubles as a switch to change between the different brush motions and brush speed. The bottom of the electric toothbrush is usually sealed shut and made of plastic. All electric toothbrushes utilize inductive charging to avoid the risk of water coming into contact with the charging base. This also means you don’t have to worry about getting an electric toothbrush wet. You can wash the entire toothbrush by soaking it in water and it won’t be spoiled.

Some other new features of electric toothbrushes include UV sanitizers and built-in timers. The timers are designed to make sure that you brush your teeth for a fixed amount of time and the UV sanitizers do the job of emitting UV light which kills at least 99% of the bacteria (or so its claimed). This is a convenient feature to keep your toothbrush clean, particularly useful if you’re not a meticulously hygienic person in the first place. An example of a sonic toothbrush that has both features is the popular Philips Sonicare FlexCare Plus and is highly recommended.
