Electric toothbrush is a kind of toothbrush invented by Philippe-GuyWoog. Through the rapid rotation or vibration of electric motion, the brush head produces high-frequency vibration, which instantly decomposes toothpaste into fine foam and deeply cleans teeth. At the same time, the vibration of bristles can promote the blood circulation of the oral cavity and massage the gingival tissue.
Electric toothbrush has set off a revolution in the field of oral health care abroad.
There are three ways to move the brush head of the electric toothbrush: one is that the brush head does reciprocating linear motion, the other is that it does rotating motion, and there is a complete set of electric toothbrush with two brush heads. The bristles of the toothbrush head are made of soft plastic fibers, and the ends of the bristles are all processed into spheres, which will not damage teeth and gums and will not affect the brushing effect. Not only can you brush every tooth clean, but you can also massage your gums. The toothbrush handle is provided with a strong/weak switching mode switch, and the moving speed of the toothbrush head can be selected according to individual needs.
According to foreign reports, in the past few years, quite a few dentists began to recommend electric toothbrushes to their patients. An electric toothbrush belongs to a tool for cleaning teeth, and consists of a rechargeable dry battery, a micro DC motor, a battery box, a toothbrush head, a metal guard plate and a sleeve. The dry battery as the DC motor power supply is installed in the battery box together with the DC motor, and the battery box is provided with a manual switch for controlling the on-off of the DC motor power supply; The rotating shaft of the DC motor extends out of the battery box, the toothbrush head and the metal guard plate are sleeved on the rotating shaft of the DC motor, and sleeves are arranged outside the toothbrush head and the metal guard plate. Electric toothbrushes with different types of toothbrush heads can be suitable for different users.
In addition to daily brushing, it can also be used to massage gums. When brushing your teeth, you can use it either electrically or manually, vertically or horizontally. By beating and rubbing gums rhythmically, blood circulation can be enhanced, and the effect of enhancing the absorption of drugs by gums is better when used in conjunction with drugs. It has good therapeutic and preventive effects on periodontitis, gingivitis, gingival bleeding and other common dental diseases. Brushing your teeth with this brush can change the habit of brushing your teeth horizontally into brushing your teeth vertically. When brushing your teeth manually, the method is the same as that of a common toothbrush.
