electric toothbrush
Electric toothbrushes use a high-speed vibration movement to drive the brush head to rotate or vibrate to achieve the effect of cleaning teeth.
Sonic toothbrush
A sonic toothbrush refers to a toothbrush whose bristles/brush head's vibration frequency is equivalent to the sonic frequency, so it is also called a sonic vibration toothbrush. It is not literally understood to use "sonic wave" to brush teeth, because it may not emit real sound waves or mechanical waves, but the rapid movement of bristles similar to the frequency of sonic mechanical waves creates a super cleaning effect that is nearly 100 times higher than that of traditional manual toothbrushes. . Compared with common rotary electric toothbrushes, the so-called "sonic toothbrush" is actually just an electric toothbrush with oscillating motion, rather than sound waves in the real physical sense. This point must be clarified.
The cavitation effect of energy in the periodontal can be used to remove the germs and impurities in the periodontal, and the cleaning range can cover all parts of the periodontal. The bristles of the brush head are transferred to the surface of the teeth and gums. On the one hand, it loosens the adhesion of plaque, tartar and small tartar to the teeth, destroys the parasitic propagation of bacteria in the gum pockets and hides on the tooth surface. At the same time, it touches the gums. The energy transferred from the bristles to the surface of the gums further penetrates into the gums. After acting on the cell membrane, it accelerates blood circulation, promotes metabolism, can inhibit gum inflammation and gum bleeding, and prevent gum atrophy.
Electric spray toothbrush
The electric spray toothbrush is filled with a can of aerosol toothpaste in the toothbrush handle. The toothpaste channel and spout are provided on the toothbrush head. The spout is hidden in the bristles of the toothbrush, and there is also a soft rubber one-way valve to block the spout. The nozzle, the aerosol toothpaste is ejected from the nozzle by pushing the soft rubber one-way valve under the action of air pressure. After turning on the electric toothbrush, the aerosol toothpaste will be sprayed on the teeth regularly and quantitatively. No matter how the bristles of the electric toothbrush are shaken, the aerosol toothpaste can completely contact the teeth and fully exert its effect. After the liquid toothpaste is used up, you can put it in another can.
Classification
Electric toothbrushes are divided into two types: plug-in power and battery-driven. Compared with traditional manual toothbrushes, electric toothbrushes are driven by electricity. The brush head moves at a speed of thousands or even tens of thousands of times per minute. The efficiency is much higher than that of manual toothbrushes, but it also has higher requirements for bristles. Damage to the gums during brushing.
With the improvement of technology, there are many types of electric toothbrushes. The general one is to clean the teeth by vibration and rotation, and some high-end ones are equipped with pulse equipment, which cleans the teeth by pulse and water spray.
