Whiter Teeth Show you the people who combat the film COUNTLESS people whom you meet today show glistening teeth. Far whiter than yours, perhaps. Let this test show you how folks get them. By fighting film Teeth are clouded by a film-that viscous film you feel. It clings tena ciously. No ordinary tooth paste can effectively combat it. Soon that film discolors, then forms dingy coats. That is why teeth lose luster. Film also holds food substance which ferments and forms acid. It holds the acid in contact with the teeth to cause decay. Germs breed by mil lions in it. They, with tartar, are the chief cause of pyorrhea. Very few who brush teeth in old ways escape these film-caused troubles. Dental science has now found two effective film combatants. One disin tegrates the film, one removes it with out harmful scouring. PROTECT THE ENAMEL Pepsodent disintegrates the film, then removes it with an agent far softer than enamel. Never use a film com batant which contains harsh grit. PAT. OFF REG. U.S. The New-Day Dentifrice Now advised by leading dentists the world over These methods have been proved by many careful tests.
