What are the characteristics of the toothbrush's cleaning method? How does it combine oscillation and vibration to remove tartar and dental plaque?

The cleaning method of the toothbrush is characterized by its combination of oscillating and vibrating actions, which enables a more comprehensive and efficient cleaning effect. For an oscillating battery-powered toothbrush, this cleaning method is specifically embodied in the following aspects:
High-frequency vibration enables the bristles to complete a large number of reciprocating movements in a very short time. This rapid and minute movement not only allows the bristles to cover every corner of the tooth surface, but also penetrates deep into the gaps between teeth and gingival sulcus, areas that are often difficult to reach with traditional toothbrushes. Additionally, the powerful cleaning force generated by high-frequency vibration can effectively remove dental plaque and tartar. Tartar, a hard and stubborn substance formed by the combination of food residue, bacteria, and minerals in saliva, is difficult to remove with traditional toothbrushes. However, high-frequency vibration can break down the structure of tartar, making it loose and easily removed by the bristles and cleaning agents in toothpaste. Dental plaque, a film composed of bacteria, adheres to the tooth surface and releases harmful substances that erode teeth. High-frequency vibration can effectively interfere with the formation of dental plaque and remove it from the tooth surface through the mechanical action of the bristles, thus reducing the risk of oral diseases. Furthermore, high-frequency vibration also promotes blood circulation in the oral cavity and improves the metabolic capacity of gingival tissue. During brushing, the slight pressure generated by the vibration promotes blood flow in the oral cavity, providing more nutrients and oxygen to the gums and helping maintain their healthy state.
Oscillating action: The oscillating movement allows the bristles to move left and right or up and down on the tooth surface, increasing the contact area between the bristles and teeth and making the cleaning process more comprehensive. Since the tooth surface is not completely flat, with various angles and depressions, the oscillating movement effectively cleans these hard-to-reach areas. As the brush head oscillates, the bristles follow its trajectory to sweep across the tooth surface. This sweeping action helps loosen tartar and dental plaque attached to the teeth, which are then removed by subsequent vibration or water flow. At the same time, oscillation distributes the cleaning agents in toothpaste evenly on the tooth surface, further enhancing the cleaning effect. Vibration alone may not thoroughly clean certain areas due to the irregularity of the tooth surface. However, oscillation compensates for this limitation by covering more tooth surfaces through the left-right or up-down movement of the bristles, ensuring that every tooth is adequately cleaned.
Combination of dual actions: When the toothbrush combines both oscillating and vibrating actions, its cleaning effect is even more remarkable. The powerful cleaning force generated by vibration deeply cleans the gaps between teeth and gingival sulcus, while oscillation ensures that the bristles cover more tooth surfaces. The two actions complement each other and enhance the overall cleaning effect. This combination not only improves cleaning efficiency but also makes the cleaning process more comfortable and effortless.
In summary, the oscillating movement plays a crucial role in the design of toothbrushes, enhancing the cleaning effect by allowing the bristles to move left and right or up and down on the tooth surface. When combined with vibration, the toothbrush can thoroughly remove tartar and dental plaque, providing comprehensive protection for oral health.
