This is with a tooth powder made of materials so fine and pure that they are absolutely soluble in the mouth fluids. Ordinary tooth powders and tooth pastes ao not completely dissolve. Little particles harden. They work down under the gum margins. Your gums become irritated. Pyorrhea develops. You may even lose your teeth from the use of this kind of paste or powder.

They know there’s just sufficient ‘‘grip’’ and “‘bite’’ in Calox to remove all products of decay from the teeth. The film and mucous placques, which serve as breeding places for germs, are removed.

The moment it comes in contact with the mouth fluids it forms Milk of Lime —the most soothing alkali you could , possibly use. Also, a paste is either slippery, soapy or oily. It slides over the surfaces of the teeth. It doesn’t ‘‘take hold,’’ and re- move the film and stain like a good powder does. All the acid is neutralized, the sensi- tive teeth are soothed, the gums are cleansed and hardened, and the enamel of the teeth protected from decay.
