The working principle of physical vibration toothbrush is that there is an electrically driven vibration motor inside the toothbrush, which can make the brush head swing perpendicular to the handle, with a small amplitude, but the swing times are very fast. However, for sonic toothbrush, this working mode is slightly backward. Sonic toothbrush no longer relies on the friction between bristles and dirt to clean teeth, so it does less harm to mouth and teeth. Although cleaning is not as strong as physical vibration, acoustic vibration is better than protecting teeth.
What are the advantages of acoustic vibration? On the one hand, its acoustic vibration can make dental plaque, dental plaque and even some unformed stones loose or even fall off. At the same time, it reacts with water and toothpaste, so that bubbles are filled around the teeth to achieve the effect of cleaning teeth. For the most difficult side teeth to brush, just press the brush head gently on the teeth at an inclined angle, and the high-frequency vibration of the acoustic toothbrush, resulting in large and high-speed water flow and vibrating bristles, can easily clean the tooth surface, tooth gaps and tooth grooves, which can greatly reduce the bleeding of gums.
Of course, the choice of these two kinds of electric toothbrushes still varies from person to person. Acoustic vibration cleaning is not strong enough and takes a long time, while physical vibration needs to control its own strength.
