Brushing your teeth is the most effective way to keep your mouth clean. Using a properly structured toothbrush, combined with the correct brushing method, removes plaque, soft scale, food debris, some pigments and prevents tartar from accumulating, making the teeth and tissues around the teeth healthy.

The medically correct method of brushing is the vertical brushing method (such as Bass method of brushing, etc.). The main point of the vertical brushing method is to brush the teeth along the growth direction of the teeth. The upper row of teeth is brushed from top to bottom, and the lower row. Brush your teeth from bottom to top.

The ordinary toothbrush that people have used for a long time is generally a "one"-shaped structure, that is, the length direction of the handle is parallel to the longitudinal direction of the brush head. This "one"-shaped toothbrush, whether it is a horizontal brush or In the vertical brushing method, there are disadvantages of lack of dental teeth or unsatisfactory. For example, the most suitable brushing method for a toothbrush with a common "one" shape is the cross brush method, but this cross brush method damages the hard tissues of the teeth (enamel, dentin), and the periodontal soft tissue (gum, Periodontal) also has damage. It can't be effectively cleaned on the level of the interdental layer and between the teeth and the gums. However, the toothbrush with the ordinary "one" shape is brushed by the vertical brush method, and the daily effort of the toothbrush is convenient and labor-saving.
