The frequent occurrence of decay of the teeth during the pregnant term has been observed by all physicians. It is attributed to many causes. I have thought that it was due to the unusual draft made upon the mother for the chemical constituents of the osseus structures of the child, especially the demand for phosphates. I have usually observed that where such a condition was present there was an unusual growth and development of the bony structures of the infant.
Under the same circumstances I have observed the occurrence of spinal irritation, and of other evidences which led me to believe that there was a lack of nutrition of the bony structures. I have been able to correct both the decay of the teeth and to overcome the spinal tenderness, by giving phosphorus or the earthy phosphates to these patients freely. In some cases the result of this treatment has been highly satisfactory.
