They Save Teeth Now Ina New Way All Statements Approved by High DentalAuthorities They End the Film Countless people now are cleaning their teeth in a new way. And modern dentists all over America are urging other people to join them. The old way proved inefficient. As millions know, they failed to prevent tooth troubles. Despite the tooth brush, tartar, decay and pyorrhea constantly became more common. Some years ago the reason was discovered. It lies in a film-a slimy film-which con stantly forms on teeth. That film gets into crevices, hardens and stays. It resists the tooth brush, and most tooth troubles are now known to be due to it. The film is what discolors, not the teeth. It hardens into tartar. It holds REG. U. S. food substance which ferments and The New-Da forms acid. It holds the acid in contact A Scientific Product-Sold with the teeth to cause decay. Millions of germs breed in it. They, with tartar, are the chief cause of pyorrhea. And many troubles besides tooth troubles are traced to this germ-breeding film. After years of research, a way has been found to combat it. Able authorities have proved this fact by adequate clinical tests. For general use the method is embodied in a dentrifice called Pepsodent.

After a few days' use you will never forget them. The basis is pepsin, the digestant of alb umin; for the film is albuminous matter. The object of Pepsodent is to dissolve the film, then to constantly prevent its accumulation. But pepsin must be activated. The ordinary agent is an acid, harmful to the teeth. For long that fact made pepsin seem impossible. Now modern science has discovered a harm less, activating method. Five governments al ready have granted patents.
