Note (35) — CANTO THIRD.

“When pains in the teeth show a disposition to change their places with great facility, like all rheumatic affections, they may yield to the most insignificant means, even to the touch of some amulet, applied with an air of mystery and confidence which imposes upon the patient. Every one knows, that in timid people, the presence of a surgeon, in most instances, is sufficient, for a time, to dispel the pain of tooth-ache. It is particularly for these pains that some dentists have a favorite odontalgic elixir, of whose sovereign virtues they are so fond of boasting. These liquors are almost all spirituous tinctures, whose powerfully stimulating action often suffices to suspend the pain.

“In fact, a drop of the tincture of opium, or any one of the essential oils, applied to the part by means of a little cotton, may produce an instantaneous abatement of the pain, but which seldom fails, sooner or later, to return. Frequent successes of this kind, of which marvellous accounts are daily published, have successfully brought into vogue numerous elixirs and various other means, all more or less ridiculous.” (Gerbaux, pp. 80, 83.)

“Doctor Sims, a celebrated practitioner in London, relates that he was such a martyr to the tooth-ache, that he was confined to his house for several weeks together by that malady, but after he avoided taking his food either hot or cold, he entirely escaped it. He was particularly careful not to take soup or any other liquid, of a temperature higher than ninety—eight degrees less than blood heat. He was induced to try this experiment, by reflecting that heat expanded all bodies. When applied to a tooth, therefore, it must diminish its cavity, compress the nerve, and consequently produce pain. However defective this theory may be, the practice of endeavoring to preserve those parts in an equable temperature, will be found to be highly important.” (Duval.—Atkinson’s translation, p. 76.)
