The rounding rate of the bristles of an electric toothbrush is one of the important elements that affects the quality of the electric toothbrush
Under the high-frequency vibration of a sonic toothbrush, if the tops of the bristles are not rounded, the irregular or even sharp surfaces will cause damage to oral soft tissues and teeth surfaces. Whether the tops of the bristles are rounded or not is difficult to tell with the naked eye, but after magnification through a microscope then you can see it. The minimum standard of the national standard rounding rate is 40%. The higher the toothbrush rounding rate, the higher the quality of the bristles.
Shenzhen Baolijie Technology Co., Ltd has strict control over the rounding rate of electric toothbrush bristles. The rounding rate of the bristles can be as high as 98%. Under a microscope, the higher the tip of the toothbrush bristles, the higher the roundness of the toothbrush, and the better it is for cleaning. The bristles that are not rounded have sharp tips and can easily cause damage and irritation to soft tissues such as gums.
