Edward Mayhew, The Horse's Mouth, Showing the age by the teeth
“ In the first place the condition of the mouth has certainly deranged the digestive organs, and, where there is room for choice, no operation, however simple or apparently safe, should be undertaken while the stomach is out of order. The seat of the disease is known, but the general health is first attended to; and when that has been in some measure re-established, the great object of the surgeon is fit to be accomplished. The question is, which of the teeth are to be interfered with? One is diseased or dead, and there can be no doubt that the diseased tooth should be removed. ”
