1. What is the working principle of acoustic wave and rotary electric toothbrush?
1, principle of acoustic wave electric toothbrush
Ultrasonic vibration toothbrush uses the high frequency vibration of micro-motor to drive the toothbrush head to swing left and right at high speed to clean the residue and plaque between teeth. The vibration speed is as high as 3 1000 times per minute, which is twice that of ordinary electric toothbrush. So the sonic electric toothbrush doesn't mean that you are brushing your teeth with sonic waves.
2, the principle of rotating electric toothbrush
Rotary electric toothbrush mainly uses the motor inside the toothbrush to drive the circular brush head to rotate. It can enhance the friction effect of the toothbrush on the teeth while performing ordinary toothbrush actions, and the selection can be as high as 15000 times per minute. This way of brushing teeth is easier to clean hidden teeth than manual brushing.
Second,
Which is better, electric toothbrush, sonic toothbrush or rotary toothbrush?
Sonic toothbrush and rotary toothbrush have their own advantages, which one to choose depends on the actual situation. When buying, choose according to your own dental conditions. If the teeth themselves are sensitive, people who suffer from oral diseases or mind using noise, it is recommended to choose a sonic toothbrush, and those who care more about the cleaning effect can choose a rotary electric toothbrush.
1. Comparison of cleaning ability: sonic rotary.
Experiments show that the dental plaque index of people who use rotating electric toothbrush is lower than that of people who use acoustic toothbrush 1/3, and rotating toothbrush can also effectively relieve and alleviate gingival inflammation. The cleaning efficiency of rotary toothbrush is indeed higher than that of sonic electric toothbrush.
2. Comparison of tooth wear: sonic rotation type.
The average tooth wear of rotary electric toothbrush is 4-5 times that of sonic toothbrush. It produces a fast rotating speed, which causes great wear on teeth. From this point of view, choosing sonic toothbrush is safer for our teeth, and the wear gap between sonic toothbrush and rotary toothbrush can be seen more clearly after using for a long time.
3. Comfort contrast: sonic rotary
In terms of comfort, the rotating toothbrush is more dynamic when used, and it is easier to make gums bleed. In contrast, the working mode of acoustic wave type is milder than that of rotary type. Moreover, the rotating toothbrush is noisy when working, which may make people who are sensitive to sound feel uncomfortable, while the acoustic toothbrush is quiet.
The above is the introduction of acoustic wave and rotating electric toothbrush. You can choose according to your actual needs. I hope the above contents are helpful to everyone.
