Do many people clean their tongues in this way?
The truth is that millions of people know about it.
It is common practice in many Asian and older cultures. Tongue cleaning was also practiced by ancient Romans and by the wealthier classes in 18th and 19th century Europe. However, for some unknown reasons, the practice did not spread widely in the West..
But now, with more research verifying its benefits, and with TV and other publicity, many dentists and hygienists are recommending it. In fact, since DrTung's introduced tongue cleaning to the USA in the mid-nineties, we have become a household name in the health industry.
