In 2016, a crowdfunding campaign to raise funds for the development of DOCTOR B toothbrushes has become one of the most successful among the many projects of the Xiaomi ecosystem. What is the secret of this useful device?
Firstly, the design of the toothbrush was developed by the famous Chinese specialist Zhang Jun, who projected the design of the Olympic Torch in Beijing in 2008.
Secondly, the brush is suitable for brushing teeth according to the Bass method. This method implies that the toothbrush head is positioned at an angle of 45 ° to the axis of the tooth. In this case, the ends of the bristles touch the lateral surface of the tooth and the gingival groove. When the brush moves, its fibers clean both spaces between the teeth and the pocket, between the tooth and the gum. This accelerates the removal of plaque and massages gums.
Thirdly, the best materials were chosen for the production of brushes. The handle is made of environmentally friendly polypropylene (PP) and three types of bristles:
- Japanese antibacterial coal yarn manufactured by Toray;
- Japanese antibacterial thread with silver ions manufactured by Toray;
- German elastic spiral threads produced by PEDEX.
This combination of high-quality materials makes it possible to provide reliable and high-quality cleaning of teeth. The toothbrush bristles are fastened by special plates from nickel-silver. This material is extremely resistant to the multiplication of bacteria.
It should be said about the special round shape of the brush head. This form has been chosen specifically to provide the owner with maximum comfort when in brushing process.
Thanks to all these strong properties the DOCTOR B toothbrush has gained recognition and immense popularity among users of China.
