How to classify toothbrushes

How to classify toothbrushes
1.Sonic toothbrush
Sonic toothbrush means that the vibration frequency of the bristles/brush head is the same or similar to the frequency of the sound wave, so it is also called a sonic vibration toothbrush. It is not literally understood to use "sound waves" to brush your teeth, but the rapid movement of bristles similar to the frequency of sound waves creates a super-cleaning effect that is nearly 100 times that of traditional manual toothbrushes.
2.Ultrasonic toothbrush
Ultrasonic toothbrush is the use of ultrasonic energy in the periodontal cavitation effect to achieve the removal of periodontal bacteria and impurities, the cleaning range can cover all parts of the periodontal. Ultrasonic energy is transmitted to the teeth and the surface of the gums through the bristles of the brush head, which loosens the adhesion of plaque, tartar and fine tartar and teeth, and destroys the parasitic reproduction of bacteria in the hidden pockets of the pockets and the tooth surface. The ultrasonic energy transmitted to the surface of the gum by the bristles that touch the gums further penetrates into the gums, acts on the cell membrane, accelerates blood circulation, promotes metabolism, inhibits inflammation of the gums and bleeding gums, and prevents gum atrophy.
3.Electric spray toothbrush
The electric spray toothbrush is equipped with a can of aerosol toothpaste in the handle of the toothbrush. The toothbrush has a toothpaste channel and a spout. The spout is hidden in the toothbrush and is also blocked by a soft rubber check valve at the spout. The spout, the aerosol toothpaste is sprayed from the spout by the action of the air pressure. After the electric toothbrush is turned on, the aerosol toothpaste will be sprayed onto the teeth at regular intervals. No matter how the bristles of the electric toothbrush are shaken, the aerosol toothpaste can completely contact the teeth and fully function. After the liquid toothpaste is used up, you can change it into a can.
