If you are looking for an electric toothbrush, often encounter Sonic and Rotating Electric Toothbrushes , what are their differences? Aiwejay explains these two kinds toothbrushes from the perspective of brushing principles .

1 . Rotary electric toothbrush principle

The rotary type is also called the mechanical rotary type, represented by Oral B , which mainly cleans the teeth physically by rotating the brush head;

It can strengthen the friction effect of the toothbrush on the teeth while performing ordinary toothbrush actions. The selection can be up to 15,000 times per minute . This method of brushing is easier to clean the hidden tooth parts than manual brushing. The cleaning ability is strong, but it is more harmful to the teeth than the sound wave.

The principle of rotating electric toothbrushes is relatively simple, that is, the motor drives the round brush head to rotate, thereby improving the friction effect when performing normal brushing actions.

Rotary toothbrushes are noisy and clean the teeth, but they wear a lot to the teeth, so long-term use is not recommended.

2 . Sonic toothbrush principle

The sonic type is basically the bristles swinging. The high-frequency vibration of the micro-motor drives the toothbrush head to swing at high speed to produce ultrasonic waves to clean the residue and plaque between the teeth . The toothbrush brands include Philips and Aiwejay electric toothbrushes.

Sonic toothbrushes have relatively little damage to the teeth, and the cleaning effect is relatively worse than that of the rotary type, but it has been able to meet the needs of users to brush their teeth.

Sonic vibration toothbrushes are more complicated than rotating toothbrushes and are more expensive. The sonic vibration type toothbrush is equipped with a vibration motor inside, which can make the toothbrush head generate high-frequency vibration perpendicular to the direction of the toothbrush handle, but the vibration amplitude is small, usually about 5 mm up and down , and the larger swing in the industry is 6 mm.

When brushing your teeth, on the one hand, the high-frequency oscillating brush head can complete the action of brushing your teeth well. On the other hand, more than 38,000 vibrations per minute will also cause a large number of small bubbles in the mixture of toothpaste and water in the mouth. The pressure generated by the bursting of the bubbles can penetrate deep into the teeth to clean the dirt.

3 . The electric toothbrush head two motion:

One is the reciprocating linear motion of the toothbrush head, and the other is the rotational motion.

The bristles of the sonic toothbrush head are made of soft plastic fibers, and the tips of the hair are spherically processed, which will not damage the teeth and gums, nor will it affect the brushing effect.

Not only can you clean every tooth, but you can also soothe your gums. The toothbrush handle has a strong and weak switch mode switch, you can choose the speed of the toothbrush head according to your needs.

4 . Clean the ability to compare

Sonic < Rotary

Tests have proved that the plaque index of people who use rotating electric toothbrushes is 1/3 lower than that of people who use sonic toothbrushes , and rotating toothbrushes are more effective in reducing and reducing gum inflammation. The cleaning efficiency of rotating toothbrushes is indeed higher than that of sonic electric toothbrushes.

5 . Tooth wear comparison

Sonic < Rotary

Rotary electric toothbrushes have an average of 4-5 times greater wear on teeth than sonic toothbrushes . It produces a very fast speed, and it wears a lot of teeth. From this perspective, the use of sonic toothbrushes is safer for our teeth, and the wear gap between sonic and rotary toothbrushes will be more visible after a long time of use.

6 . Comfort contrast

Sonic > Rotary

In terms of comfort, the vibration of the rotating toothbrush is greater when in use, and it is easier to bleed the gums. In contrast, the sonic working method is gentler than the rotating toothbrush. Moreover, the noise generated by rotating toothbrushes is louder, which may make people who are sensitive to sound feel uncomfortable, while sonic toothbrushes are quieter.
