In principle, there are two major categories of electric toothbrushes: rotation and vibration. Rotary toothbrushes have a simple principle, that is, the motor drives the round brush head to rotate, which enhances the friction effect while performing ordinary brushing actions. Long-term use is not recommended due to large wear and tear.
The vibration type toothbrush is more complicated and more expensive in terms of price. There is an electric-driven vibration motor inside the vibration type toothbrush, which can make the brush head produce high-frequency swings perpendicular to the direction of the brush handle, but the swing amplitude is very small, generally about 5 millimeters up and down, and the largest swing in the industry is 6. Mm.
When brushing teeth, on the one hand, the high-frequency swinging brush head can efficiently complete the action of scrubbing the teeth. On the other hand, the vibration of more than 30,000 times per minute also causes the mixture of toothpaste and water in the mouth to produce a large number of tiny bubbles, which are generated when the bubbles burst. Pressure can penetrate deep into the teeth to clean dirt.
Electric toothbrushes use a high-speed vibration movement to drive the brush head to rotate or vibrate to achieve the effect of cleaning teeth.
Eolding 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 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 transmitted 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 the hiding places of the tooth surface, and at the same time, by touching the gums The energy transferred from the bristles to the gum surface 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. In the spout, the aerosol toothpaste is ejected from the spout 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 replace it with another can.
It is difficult for traditional toothbrushes to completely remove dental plaque, coupled with improper brushing methods, the cleaning effect of brushing teeth is greatly reduced. Experiments have proved that electric toothbrushes remove 38% more plaque than manual toothbrushes, and its cleaning ability has been unanimously affirmed by dental experts.
Incorrect brushing methods make our gums often suffer. The slight vibration generated by the high-speed rotation of the electric toothbrush can not only promote the blood circulation in the oral cavity, but also have an unexpected massage effect on the gum tissue, and this comfortable feeling can only be known after personal experience.
This applies not only to many children who do not like brushing their teeth, but also to adults. Since the volume of the electric toothbrush is much larger than that of the traditional toothbrush, it has a lot of effort in appearance. Watching a "sports car" "running" back and forth in front of my mouth, brushing my teeth has naturally become a pleasure.
When using an ordinary toothbrush to brush the teeth, the intensity of use is controlled by the user. Sometimes it is inevitable that the brushing force is too strong, or the incorrect see-saw horizontal brushing method is used, which will cause damage to the teeth and gums. Experiments have shown that electric toothbrushes can reduce the intensity of brushing by about 60%, reduce the frequency of gingivitis and gum bleeding by 62%, and make the brushing process safer and more effective.
Whitening and beautiful
Electric toothbrushes can effectively reduce tooth stains caused by drinking tea, coffee and bad oral conditions, and restore the original color of teeth. And this adjustment is not immediate effect, but gradually with the daily brushing, and will not cause any damage to the teeth themselves.
