周期牙刷 / Periodically toothbrush

周期牙刷

In daily life, the service life of the tooth brush cannot be identified, and we are unable to determine when to replace them. According to this problem, it can be solved by changing the color of the brush hair itself which may remind us of the replacement. When we brush our teeth, the bacterial on the toothbrush will residue to the bristles of the brush. In 3-4 weeks the bacteria will multiply, and gradually turn the color of the brush hair from white into a deep yellow, in order to remind people to replace a new toothbrush.
