best electric toothbrush

The researchers conducted an interesting observation - when meeting people pay attention primarily on the eyes and smile at him. A pledge of a beautiful and charming white smile and healthy teeth. To a large extent it is promoted properly chosen toothbrush.

The first electric toothbrushes appeared around 1950. Initially, their design was flawed. Bristles can rotate only in one plane, which led to rapid abrasion of tooth enamel, and did not contribute to clean teeth. With the development of modern technologies of electric toothbrush helps prevent oral diseases. Currently, there are three types of electric toothbrushes, they are divided on the basis of plaque removal. But they all need electricity to operate, and in all of them as a power source using a penlight batteries or rechargeable batteries, rechargeable from the mains.

The bristles, which make about 18 thousand revolutions per second, effectively remove food debris and soft plaque. Due to the rapid rotation and high frequency amplitude arises dynamic flow of liquid from a mixture of saliva, water and toothpaste, which penetrates well between the teeth and perfectly cleans the teeth. In this type of ultrasonic toothbrushes integrated ultrasound generator frequency ultrasound destroys the germs and bacteria attach to the tooth surface.

Inside the ultrasonic electrical brush has a piezoceramic disc, which is located under the bristles and the motor. Thanks to this record, emitting a wave oscillating around 1.7 MHz, the bristles vibrate and make approximately 100 million movements in just one minutu.Takaya rate fluctuations have an impact of up to 4 mm in depth, which makes it easy to clean hard to reach areas in the mouth.

Electric brushes can be used only in the case of healthy teeth and gums, dentists are advised to alternate this with a conventional brush. Ultrasonic Toothbrush creates vibrations fillings and dentures, which causes reduction of the term of service of fillings, crowns, dentures and other prosthetic. In a healthy tooth oscillation wave propagates without any problems, whereas the difference in materials causes a conflict at the interface between the filling and the tooth, for example. The destruction occurs gradually.
