For exogenous shaded teeth, coffee, tea, smoking and red wine are the culprit. According to statistics, there are 15% ~ 25% of smokers in China. The female smokers are also included.

That is to say, there are 200 to 300 million people who have yellow or black teeth in China. Besides, the impact of coffee, wine and tea should not be neglected. Nowadays due to the pressure from work and study, people are used to drinking tea, coke, coffee, etc. Once the pigment from the food deposits on the teeth, it is difficult to remove. Our daily life can’t be without water. With the continuous improvement of living standard, people require water with higher quality. This need not doubt that only clean water can ensure our health.
