Electric toothbrushes use a high-speed motor to make the brush head rotate and vibrate to achieve dental cleaning. For example, Best dent's BD-5C is vibrating around 40,000 beats per minute, loosening hidden plaque, turning around 8,800 times per minute, removing loose plaque.
Ultrasonic toothbrush uses ultrasonic energy to remove periodontal pathogens and impurities from the periodontal cavitation effect, and the cleaning range can cover all parts of the periodontal area. Ultrasonic energy is transmitted through the bristles of the brush head to the surfaces of the teeth and gums. On the one hand, it loosens the adhesion of plaque, tartar, and tiny gravestones and teeth, destroying the parasitic growth of bacteria in the sagging bags and hidden places on the tooth surfaces. The ultrasonic energy that touches the gums of the gums and transmits them to the surface of the gums penetrates further into the gums. After acting on the cell membrane, it accelerates blood circulation, promotes metabolism, inhibits inflammation of the teeth and bleeding gums, and prevents the gums from shrinking.
The scientific definition is: Sonic toothbrush toothbrush refers to the bristles/brush head vibration frequency and the sound wave frequency is the same or similar, it is also called the sound wave vibration toothbrush. It is not literally understood to use "sonic waves" to brush teeth, but the rapid movement of bristles, which is similar to the frequency of acoustic vibrations, has created a super-strong cleaning effect that is nearly 100 times greater than that of conventional manual toothbrushes, but also the health benefits of massaging gums and whitening/firm teeth. It is the toothbrush with the highest technological content so far and the best cleaning and health care effect.
