Two reasons fo FILM is found toplayan a important part in tooth decay Y .. to cause unsightly stains Three rules for fighting it Interesting theories on what makes teeth decay. What to do ATTHORITIES now believe there are two causes of common tooth decay. One is the lack of essential food elements in diet . . . interior tooth structure when under-nourished shows a tendency to disintegrate and offers "low resistance" to disease. The second cause is germs-or to be more accurate, acids manufactured by germs. These dissolve enamel and attack the part beneath. Pepsodent tooth paste was devel oped to remove the "outside" enemy of teeth. Only your diet can help you fight trouble from within. Remove film on teeth On your teeth a coating forms called film. It is most prevalent after eating and on rising in the morning. Film is ugly. It absorbs the stains from food and smoking. It dims teeth's natural sparkling brilliance. Film attracts the germs associated with decay. It glues them tightly to the tooth's enamel.What's more, film makes an ideal incubator in which germs grow and multiply. Film must be removed twice every day. A new cleansing material Recently Pepsodent laboratories made a notable discovery-a cleans ing and polishing material entirely new and different. This material is unsurpassed in removing stained, destructive film. It imparts a higher brilliance to tooth enamel. And, last of all, this new material is SAFE safe, because it's soft, twice as soft as polishing material in common use. Because of its great safety it is urged for cleansing baby teeth and for polishing delicate enamel. It marks the pinnacle in modern tooth paste.
