Life Toothbrush
Life Toothbrush

The number of bacteria on the toothbrush-head increases with time. And dental problems may occur when it exceeds 400,000. However, almost 50% of all people do not take their own dental health seriously. About 90% do not know when to change their toothbrushes.
Life Toothbrush can monitor the bacteria quantity of its brush head and show the information by changing the color of its brush holder, so as to remind the user to change the brush head. Life Toothbrush aims to help people pay more attention to their dental health.
