To protect teeth is a very important thing. Toothbrush plays a very important role. Experts think the toothbrush may be changed once every three months, because toothbrush will accumulate a certain quantity of bacteria in three months, which can cause teeth cleaning strength decreased, and bacterial growth and lead to tooth decay. In life, many people don't care the details, so I designed a toothbrush, which will changes over time. Green will gradually become brown in three months until vanishing. Vanishes. Remind people to change toothbrush. I hope more and more people will aware of the problem.
