he Diseases of the Teeth, which are sometimes so tedious and so violent, as to cause obstinate Wakefulness, a considerable Degree of Fever, Raving, Inflammations, Abscesses, Rottenness of the Bones, Convulsions and Faintings, depend on three principal Causes. 1. On a Caries or Rottenness of the Teeth. 2. On an Inflammation of the Nerves of the Teeth, or of the Membrane which invests and covers them; and which affects the Membrane of the Gums. 3. A cold Humour or Defluxion that is determined to the Teeth, and to their Nerves and Membrane.
§ 138. In the first of these Cases, the Caries having eat down to, and exposed the naked Nerve, the Air, Food and Drink irritate, or, as it were sting it; and this irritation is attended with Pain more or less violent. Every thing that increases the Motion or Action of the affected Part, as Exercise, Heat or Food, will be attended with the same Consequence.
When the Tooth is greatly decayed, there is no other Cure besides that by extracting it, without which the Pain continues; the Breath becomes very offensive; the Gum is eat down; the other Teeth, and sometimes even the Jaw-bone, are infected with the Rottenness: besides, that it prevents the Use of the other Teeth, which are infected with a kind of tartarous Matter, and decay.
But when the Disorder is less considerable, the Progress of it may sometimes be restrained, by burning the Tooth with a hot Iron, or by filling it with Lead, if it is fitted to receive and to retain it. Different corroding Liquids are sometimes used on these Occasions, Aqua fortis itself, and Spirit of Vitriol: but such Applications are highly dangerous, and ought to be excluded. When the Patients, from Dread, reject the Operations just mentioned, a little Oyl of Cloves may be applied, by introducing a small Pellet of Cotton, dipt in it, to the rotten hollow Tooth; which often affords considerable Ease, and Respite. Some make use of a Tincture of Opium, or Laudanum, after the same Manner; and indeed these two Medicines may be used together in equal Quantities. I have often succeeded with Hoffman's mineral anodyne Liquor; which seemed indeed, for a few Moments, to increase the Pain; but Ease generally ensues after spitting a little Time. A Gargarism made of the Herb Argentina; that is Silver-weed or wild Tansey, in Water, frequently appeases the Pain that results from a Caries of the Teeth: and in such Cases many People have found themselves at Ease, under a constant Use of it. It certainly is an Application that cannot hurt, and is even beneficial to the Gums. Others have been relieved by rubbing their Faces over with Honey.
§ 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.
§ 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.
§ 141. When the Disease arises from a cold Distillation, or Humour, tending to these Parts, it is commonly (though equally painful) attended with less violent Symptoms. The Pulse is neither strong, full nor quick; the Mouth is less heated, and less swelled. In such Cases, the afflicted should be purged with the Powder [Nº. 21], which has sometimes perfectly cured very obstinate Complaints of this Sort. After purging they should make Use of the Diet Drink of the Woods [Nº. 22]. This has cured Tooth-achs, which have baffled other Attempts for many Years; but it must be added, this Drink would be hurtful in the Disease from a different Cause. Blisters to the Nape of the Neck, or [35] elsewhere, it matters not greatly where, have often extraordinary good Effects, by diverting the Humour, and restoring a compleat Perspiration. In short in this Species, we may employ, not only with Safety, but with Success (especially after due purging) Pills of Storax, Opium and Venice Treacle. Acrid sharp Remedies, such as hard spun [35] Tobacco, Root of Pellitory of Spain, &c. by exciting much Spitting, discharge part of the Humour which causes the Disease, and hence diminish the Pain. The Smoke of Tobacco also succeeds now and then in this Disorder, whether this happens from the Discharge of the Rheum or Spittle it occasions; or whether it is owing to any anodyne Efficacy of this Plant, in which it resembles Opium.
