The works of Hippocrates are nearly silent on the hygiene of the teeth; but in the second book, on the diseases of women,[50] some prescriptions are to be found against bad-smelling breath. We translate the passage integrally: “When a woman’s mouth smells and her gums are black and unhealthy, one burns, separately, the head of a hare, and three mice, after having taken out the intestines of two of them (not, however, the liver or the kidneys); one pounds in a stone mortar some marble or whitestone,[51] and passes it through a sieve; one then mixes equal parts of these ingredients and with this mixture one rubs the teeth and the interior of the mouth; afterward one rubs them again with greasy wool[52] and one washes the mouth with water. One soaks the dirty wool in honey and with it one rubs the teeth and the gums, inside and outside. One pounds dill and anise-seeds, two oboles of myrrh;[53] one immerses these substances in half a cotyle[54] of pure white wine; one then rinses the mouth with it, holding it in the mouth for some time; this is to be done frequently, and the mouth to be rinsed with the said preparation fasting and after each meal. It is an excellent thing to take small quantities of food of a very sustaining nature. The medicament described above cleans the teeth and gives them a sweet smell. It is known under the name of Indian medicament.” In the book _De affectionibus_ there is a passage where it is said that inflammation of the gums is produced by accumulations of pituita, and that, in like cases, masticatories are of use, as these remedies favor the secretion of saliva, and thus tend to dissipate the engorgement caused by pituita. Still more important, however, is the following passage of the same book:[55] “In cases of toothache, if the tooth is decayed and loose it must be extracted. If it is neither decayed nor loose, but still painful, it is necessary to desiccate it by cauterizing. Masticatories also do good, as the pain derives from pituita insinuating itself under the roots of the teeth. Teeth are eroded and become decayed partly by pituita, and partly by food, when they are by nature weak and badly fixed in the gums.” Hippocrates, therefore, considers affections of the teeth to depend in part on natural dispositions, that is, on congenital weakness of the dental system, in part on accumulations of pituita, and the corroding action of the same. If a painful tooth were not loose, it was not to be extracted; but one was to have recourse to cauterization and to masticatories, intended the one and the other to dissipate the accumulation of pituita, believed by him to be the cause of toothache.
