Compared with ultrasonic toothbrushes, what is the difference in the cleaning principle of Sonic Rechargeable Electric Brush?

Sonic Rechargeable Electric Brush use the motor built into the body to cause high-frequency vibrations, driving the brush head to produce high-frequency swings perpendicular to the direction of the brush handle. The amplitude of this swing is small, generally about 5 mm up and down, and the oral cavity is cleaned by continuous up and down brushing and the impact of water flow caused. Ultrasonic toothbrushes generate oscillation waves through the oscillation circuit board inside the brush body, which are then transmitted to the ultrasonic transducer chip built into the brush head, output ultrasonic waves, and transmit them to the bristles at an extremely high vibration frequency, emitting ultrasonic energy to deeply clean the teeth and mouth. The vibration frequency of Sonic Rechargeable Electric Brush is generally around 22,000 times/minute. The vibration frequency of ultrasonic toothbrushes is extremely high, usually above 24 million times/minute, which is much higher than that of sonic electric toothbrushes.
Sonic Rechargeable Electric Brush mainly achieve cleaning through the flow cleaning force caused by high-frequency vibrations. High-frequency vibration will instantly break down toothpaste into fine foam, and through the water flow caused by the vibration of the electric toothbrush, the strong flow cleaning force will penetrate deep into the teeth for full cleaning, which can effectively crush dental calculus, flush dental plaque, and strongly remove stubborn tooth stains.
Ultrasonic toothbrushes use the cavitation effect of ultrasonic waves in the periodontium to remove dental plaque and impurities. When the sound waves vibrate at high frequency, the water in the mouth will form countless tiny bubbles that are invisible to the naked eye. These bubbles burst instantly and generate huge energy, thereby separating dental plaque, dental plaque, and dental calculus from the teeth, achieving the effect of cleaning teeth.
The cleaning range of the sonic charging electric toothbrush is mainly limited to where the bristles can reach. Although a better cleaning effect can be achieved through high-frequency vibration and water flow impact, there may still be some dead corners. The ultrasonic toothbrush has a wider cleaning range and can cover all parts of the periodontal tissue, including hard-to-reach areas such as the gaps between teeth and under the gums. Its cleaning effect is also more thorough, which can effectively reduce the problems of gingival bleeding and gingivitis.
Sonic rechargeable electric toothbrushes require a certain amount of force to hold and clean teeth, but the overall feeling is relatively gentle and suitable for most people. When using an ultrasonic toothbrush, you don't need to use force to clean your teeth. Just put the brush head on the tooth surface and let the high-frequency vibration generated by the ultrasonic wave help clean your teeth, which is easier and safer to use.
Sonic rechargeable electric toothbrushes provide a variety of bristle types (such as soft bristles, hard bristles, sensitive types), brush head sizes (standard/small) and special function brush heads (orthodontic, tongue cleaning). Users can choose exclusive brush heads according to gum sensitivity, tooth arrangement or special oral problems (such as braces, dental implants) to improve cleaning accuracy and comfort. Customized brush heads are all made of DuPont material, and the wavy lines fit the contours of the teeth, enhancing the cleaning effect while protecting the gums.
