Electric Toothbrush
Nylon bristles first appeared in toothbrushes in 1938, and the electric toothbrush was introduced a year later in Switzerland. The electric toothbrush was introduced into U.S markets only in the 1960s. The electric toothbrush models then operated on rechargeable batteries. The electric toothbrush was not very popular until the 1990s; when studies proved that the electric toothbrush does indeed clean better than ordinary toothbrushes. Nowadays, these electric-powered teeth cleaning devices are found just about anywhere, even at the supermarket!
An electric toothbrush can be a best alternative to a manual toothbrush, especially if you have poor manual dexterity, or if you have little motivation to brush your teeth well. Cleaning your teeth with an electric toothbrush ensures consistent speed and performance, because a high-speed vibrating movement induces the bristle ends to remove plaque quickly and effectively from your teeth and improve your gum health. The movement of the brush head is in an oscillating pattern that helps clean gently between the teeth and in the far corners of your mouth. That's called good oral hygiene and it means you won't have to go to the dentist quite so often. The cleaner you keep your teeth, the longer they'll last you.
Toothbrushes are generally classified based on their bristle types as very soft, soft, medium, hard and very hard. The soft bristled toothbrushes are intended for kids and are also beneficial for adults with gum disease to clean without injuring gums.
The hard and very hard bristled toothbrushes are often used by adults with healthy gums which effectively clear chewing surfaces of the teeth and at the tendency to the raised formation of dental adjournment. Some electric toothbrush models even have a timer to let you know if you have been brushing the required amount of time. Some types of electric toothbrush have a washable brush compartment. The entire unit of the electric toothbrush offered by some brands can be cleaned safely under water.
The electric toothbrush unit is a completely sealed one. The electric toothbrush rests on the charger without any metal contacts that connect the toothbrush to the base. This arrangement is called inductive charging, where the toothbrush and the base form a two-part transformer.
As long as you have good brushing habits and floss at least once daily, your teeth will be healthy whether you choose an electric toothbrush or one that's manual.

Electric Shaver/Razor |
Electric Shaver/Electric Razor
The Remington Company introduced the first electric shaver in 1937. The company improved upon the electric razor model by adding a second blade. The cordless electric shaver model arrived in 1960 with the addition of rechargeable batteries. About 1985, a flexible foil was introduced, but the original electric razor design is still used today. In the cordless mode, the electric shaver is completely immersible in water.
The electric razor is basically a simple gadget consisting of:
- A rechargeable battery
- A switch
- An electric motor
- A gear system
- The blades that cut the whiskers
All of the above parts are arranged compactly inside an electric razor. The batteries and motor form a unit. A printed circuit board (PCB) contains the charging system and the batteries are bonded to the PCB. A tiny auxiliary PCB contains two LEDs that indicate the following:
- The batteries need recharging
- The electric razor is on
- The electric razor is recharging
The shafts on which the rotating blades engage mesh with the electric motor's gear in a direct drive system.
