Those Pearly Teeth Learn how people get them All statements approved by high dental authorities Millions of people have adopted a new teeth-cleaning method. Wherever you look you see pearly teeth nowa days. Let this ten-day test reveal what this method means to you. End the cloudy film Most teeth are dimmed by film. A viscous film clings to them, enters crevices and stays. Most tooth troubles are now traced to it. It is this film-coat that dis colors-not the teeth. It is the basis of tartar. It holds food substance which fer ments and forms acid. It holds the acid in contact with the teeth to cause decay. Millions of germs breed in it. They, with tartar, are the chief cause of pyorrhea, and very few people escape it. The ordinary tooth paste does not dissolve it, so the tooth brush does not end it. Thus most people suffer from that film. Now dental science, after years of searching, has found a way to combat it. Able au thorities have amply proved its efficiency. Now leading dentists everywhere advise it, and millions of people have come to employ it. Everyone is welcome Now this new method is em bodied in a dentifrice called Pepsodent. And everyone is welcome to a ten-day test. Pepsodent is based on pep sin, the digestant of albumin. The film is albuminous mat ter. The object of Pepsodent is to dissolve it, then to day by day combat it. Pepsin long seemed impos sible. It must be activated, and the usual agent is an acid harmful to the teeth. But science has found a harmless activating method, and pep sin can be every day applied. Two other new-day requi sites are combined in Pepso dent. So this method in three ways brings unique results, and everyone should know them. Send the coupon for a 1o Day Tube. Note how clean the teeth feel after using. Mark the absence of the vis cous film.
