The condition of the teeth is influenced to a large extent by the state of the stomach. Where the digestion is perfect, the breath free from all foul odors, the teeth are less liable to decay and tartar rarely accumulates. Where there is any stomach disorder, however, very great
care must be taken to avoid a number of unpleasant symptoms associated with the gradual deterioration of the teeth. If the various suggestions I have made in this volume for maintaining superior health are followed with a reasonable amount of care, and the tooth brush is used regularly, in addition to proper attention being given to thorough mastication, the teeth should be retained as long as there is use for them. Remember, however, the very important suggestion made in another chapter in reference to the value of fruit acid in cleansing the mouth and teeth. If you will rinse the mouth out at frequent intervals with the juice of an orange or eat part or all of an orange, you will be surprised at the cleansing influence of this acid fruit. Almost any acid fruit will be of value, but the orange is perhaps the best for this purpose. The free use of water to insure alimentary cleanliness together with the acid fruit habit will form a very superior insurance for our teeth.
Finally, and of not least importance, the character of the diet has a great influence on the teeth. You cannot keep the teeth sound and strong if the foods you eat do not contain the material out of which teeth are built. If the food elements that build teeth and bone are lacking, you cannot expect the teeth to last long. A great hue and cry has been raised about the poor teeth of the school children of to-day, and an effort is being made to teach the children to brush their teeth. Of course this is good as far as it goes, but it does not go far when the children are fed upon a diet that is defective. When you find the child of a poor family given a diet of little more than white bread and coffee you can absolutely depend upon it that his teeth are crumbling and decaying. No other result is possible, no matter if the greatest of care is used to keep the teeth well brushed and clean.
Therefore, my remarks in another chapter upon the influence of refined foods will apply particularly in the case of the teeth. A satisfactory supply of lime in the diet is especially necessary for building teeth and bone. Whole-wheat bread will supply the material for building sound teeth, while oatmeal and other whole grain foods are almost equally satisfactory for this purpose.
Some women lose their teeth rapidly as a result of pregnancy, because the diet upon which they live is really a starvation diet so far as these important elements are concerned. Eggs are rich in lime and elements required for building strong teeth, while vegetables and fruits in their natural state are valuable in this way. Good milk is of value for its supply of lime and other organic minerals in the case of young children. Furthermore, all natural foods that provide good exercise for the teeth through the necessity for mastication are valuable on this account for strengthening the teeth, as I have already said.
Dentistry is one of our most useful professions. But there would be need for few dentists if the suggestions given in this chapter were closely followed by men, women and children the whole country over. One may have strong teeth in practically every instance, as a result of proper care and suitable diet, just as he may have strong muscles, strong organs and strong nerves.
