Sec. 139. The second Cause is the Inflammation of the Nerve within the Substance, or of the Membrane on the Outside, of the Tooth. This is discovered by the Patient's Temperament, Age and Manner of living. They who are young, sanguine, who heat themselves much, whether by Labour, by their Food, their Drink, by sitting up late, or by any other Excess: they who have been accustomed to any Discharges or Eruptions of Blood, whether natural or artificial, and who cease to have them as usual, are much exposed to the Tooth-ach, from this Cause. This Pain, or rather Torment, if in an acute Degree, commonly happens very suddenly, and often after some heating Cause. The Pulse is strong and full; the Countenance considerably red; the Mouth extremely hot: there is often a pretty high Fever, and a violent Head-ach. The Gums, or some Part of them, become inflamed, swelled, and sometimes an Abscess appears. At other times the Humours throw themselves upon the more external Parts; the Cheek swells, and the Pain abates. When the Cheek swells, but without any Diminution of the Pain, it then becomes an Augmentation, but no essential Change, of the Disorder. Sec. 140. In this Species of the Disease, we must have Recourse to the general Method of treating inflammatory Disorders, and direct Bleeding, which often produces immediate Ease, if performed early. After Bleeding, the Patient should gargle with Barley Water, or Milk and Water; and apply an emollient Cataplasm to the Cheek. If an Abscess or little Imposthume appears, the Suppuration or ripening of it is to be promoted, by holding continually in the Mouth some hot Milk, or Figs boiled in some Milk: and as soon as ever it seems ripe, it should be opened, which may be done easily, and without any Pain. The Disorder, when depending on this Cause, is sometimes not so violent, but of a longer Duration, and returns whenever the Patient heats himself; when he goes to Bed; when he eats any heating Food, or Drink, Wine or Coffee. In this Case he should be bled, without which his other Medicines will have little Effect; and he should bathe his Feet in warm Water for some Evenings successively, taking one Dose of the Powder No. 20. Entire Abstinence from Wine and Meat, especially at Night, has cured several Persons of inveterate and obstinate Maladies of the Teeth. In this Species of Tooth-ach, all hot Remedies are pernicious; and it often happens that Opium, Venice Treacle, and Storax Pills, are so far from producing the Relief expected from them, that they have aggravated the Pain.
