The Errors Made in Tooth Pastes 



All Statements Approved by High Dental Authorities 



Why They Failed We Now Use Pepsin 



The evidence shows that the tooth-brush needs aid. 

 Tooth troubles have constantly increased. Millions 

 find that well-brushed teeth still discolor and decay. 



Modern dentists know the reason. It lies in a 

 film— a slimy film— which brushing does not end. 

 Most tooth trouble finds its source in that film. 



That film is what discolors — not your teeth. It 

 hardens into tartar. It gets into crevices and stays. 

 It holds food which ferments 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. So any brushing 

 which omits that film does very little good. 



Tooth pastes have aimed to remove food debris, 

 or counteract acid, or combat germs. But the cause 

 of tooth troubles lay imbedded in film, where the 

 tooth-brush failed to reach them. 



Science now has found a way to combat that film. 

 Able authorities have proved it by clinical tests. It is 

 now embodied in a dentifrice called Pepsodent, and 

 we are asking all to prove it by a simple trial test. 



That film is albuminous, so Pepsodent is based on 

 pepsin, the digestant of albumin. The object is to 

 dissolve the film, then to constantly prevent its ac- 

 cumulation. 



Ordinary pepsin mixtures cannot serve this pur- 

 pose. Pepsin must be activated, and the usual agent 

 is an acid harmful to the teeth. 



But science has discovered a harmless activating 

 method. Five governments have already granted 

 patents. It is that method, used in Pepsodent, which 

 makes it possible nowadays to keep teeth from film 

 accumulation. 



Many clinical tests have proved the effects cf 

 Pepsodent. They are now beyond possible question. 

 You can prove them yourself, and in one week, if 

 you will make the test. 



Send the coupon, with 10 cents, for a special trial 

 tube. Use it like any tooth paste and watch results. 

 Note how clean the teeth feel after using. Mark the 

 absence of the slimy film. See how teeth whiten as 

 the fixed film disappears. 



A short trial will give you a new conception of what 

 teeth-cleaning means. And we do not believe you 

 will ever return to old, inefficient methods. Cut out 

 the coupon now.
