It is estimated that less than half of the rural population and only 10% of Chinese city dwellers have proper dental hygiene! It's so bad that many people resort to using twigs or green tea to clean their teeth, either out of tradition or out of necessity due to poverty. Even former chairman Mao Zedong is said to have had teeth that were stained green! Currently, for every 60,000 people in China, there is only one dentist.
