Book excerpt: Excerpt from A Treatise on the Use of Adhesive Gold Foil The nature of that destructive process to which the teeth are subject, and to which the term caries has been applied, from its supposed resemblance to a disease of the bones, so designated, is easily understood. The teeth are, principally, made up of phosphate of lime, which is invariably decomposed when contact between it and a certain class of agents, acids, occurs. There is no part of the calcareous portion of a tooth which is not liable to be acted upon by the agents referred to. The fluids contained in the mouth are generally more or less acid in their character. The quantity of acid, however, in proportion to the quantity of these fluids, is small, often scarcely perceptible under ordinary tests. So slight is the proportion of acid in the fluids of the mouth, that no injurious impression is made by them upon those surfaces of the teeth exposed to the friction of the lips and cheeks, and of mastication. In order to exercise upon the base of the teeth, their legitimate influence, it is necessary that the fluids of the mouth should be retained undisturbed in contact with the teeth for some time.
