Dentition

“ The brain of the hare can, by being rubbed on the gums and jaws, serve for two important purposes, since it has not only the virtue of facilitating dentition, but also of making teeth grow again to those who have lost them! The brain of a partridge applied to a carious tooth makes it fall in pieces!
The treatment of odontalgia embraces, according to Gaddesden, both general and special means of cure. To the former belong purgatives, bloodletting, scarifications of the labial and sublingual mucous membrane, leeches, the application of scarified cuppings under the chin. ”

“ In cases of difficult dentition, the best remedy, according to Musitano, for facilitating the eruption of the teeth consists in friction of the gums, once, or at most twice, with blood drawn fresh from the comb of a cock!249 If, however, even this remedy fails to produce the desired effect, it will then be necessary to lance the gum at the point where the tooth is to erupt, or to press it hard with the thumb, that the tooth may the easier come through. ”

“ We do not, of course, know how often the question has applied to the actual and complete loss of the teeth, or only to some interference with the teeth cutting the gum, occasioned by a limitation of the necessary space. However, it must be remembered that the shortening of the jaw stands in direct correlation with the reduction of the dentition. A prediction of the man of the future is given us by Cope: the lower races of men will retain the dentition of the present day, incisors , canines , premolars , molars ”

“ A. Westphal. In proof of the great utility of lancing the gums in cases of difficult dentition, A. Westphal reports a case in which the difficult eruption of an upper canine tooth provoked considerable inflammation and protrusion of the eye on the same side as the tooth ”

“ In cases of chorea or epilepsy, of eye or ear troubles, or of any morbid condition not otherwise accounted for, occurring during the period of the second dentition, especially at the sixth, twelfth, and seventeenth years, or until the wisdom teeth are fully erupted, it is well to inspect the mouth and to think of dentition as the possible cause.
PROGNOSIS.—The prognosis will depend upon the character and gravity of the associated symptoms, the presence or absence of diathesis, and the etiological importance attached to dentition. It is impossible to lay down a general law. ”

“ Just as the absence of hair on the face in a man or a moustache effect in a woman stand for some definite stress or strain in the mechanics of interaction of the internal secretions, so likewise do variations in dentition, as to the time of eruption of the teeth, their position and quality, and their resistance to decay. ”

“ Wherefore, the opinion of those who consider that the first teeth are formed from the milk,180 and those of the second dentition from food and drink, must be declared entirely false. In fact, by opening both jaws of a stillborn fetus, one may find, on each side of each jaw, the incisors, the canine, and three molars, partly mucous and partly osseous, and already sufficiently large and entirely surrounded by their alveoli. Then removing, with a skilful hand, the incisors and the canines, there may be observed a very thin partition only just ossified ”

“ In the last chapter of Book XVIII, first dentition and the treatment required during this period are spoken of. The cutting of teeth, says Paré, is accompanied by pain, itching, and pricking of the gums; often, as well by diarrhea, fever, epileptic convulsions, which sometimes end fatally. The symptoms by which it may be known that teeth are about to come forth are as follows: The wet-nurse feels the mouth of the suckling infant to be hotter than usual; the gums are swollen; the child is restless, crying often and sleeping but little ”

“ There are few adults who cannot describe the pangs of tooth-ach from their own feelings. It is generally intermittent, seldom dangerous to life, except during the{263} first dentition of infancy. Its constant symptoms, pain, flow of saliva, restlessness: its variable symptoms, swelled face, carious loosened teeth; fistula, exostoses of the gums and jaws. The causes, inflammation of the periosteum of the teeth, gums, or jaw; suppressed perspiration; moist air; catarrhal defluxion; suppressed habitual evacuations, nasal hemorrhage and venesection; plethora; intermittent, scorbutick, arthritick ”

“ This author condemns as harmful the use of hard substances (such as bone rings, etc.) that people are in the habit of putting into children’s hands during the period of the first dentition, in the idea that by pressing these objects between the gums, as children instinctively do, they cut their teeth more easily. As to emollients, he holds them to be completely useless, and prefers to all these remedies the use of lemon juice. ”

“ While, therefore, it cannot be maintained that all healthy children cut their teeth in a certain regular order and time, yet it is certain that those children who follow the general rule which prevails in this respect, suffer least from the difficulties and effects of dentition. ”

“ INSECTIVORA, an order of non-volant placental mammals of small size, with a dentition adapted to an insect-diet. In nearly all cases these creatures are nocturnal, and the majority are terrestrial, many burrowing in the ground, although a few are arboreal and others aquatic. They have plantigrade or partially plantigrade feet, that is to say, they apply the whole or the greater portion of the soles to the ground when walking; and there are generally five toes, each terminating in a claw, and the first never being opposable to the others in either the fore or hind limb. ”

“ These little germs always get into places that are not kept clean, and when they get into the mouth they go to work, like so many little carpenters, with pick and drill, and pick away the [60] outer covering of the tooth and then the tooth decays, and this causes toothache.
We all want to have pretty white teeth like Ned's, do we not? When we are little we must take care of the teeth, and if they begin to decay we must have them filled or treated by the dentist. Let us look at our teeth and see who has the prettiest and the best ones. Has every one a toothbrush? We must each have one. ”

“ A moment's reflection will show the folly of extracting teeth to make room for those out of alignment, and modern dentistry has
proved that such extraction will defeat the object for which it is undertaken, viz., the restoration of the perfect denture. A man who will extract a tooth in regulating may be foolishly clinging to the old tradition, that was spoken of just now, that the unfortunate child had inherited large teeth from one parent, and small jaws from the other. ”

“ There is infection; therefore, the first thing to do is to remove the pus.
Dental Treatment.—If there is a large cavity in the tooth, try to enter the root canals and remove the putrescent matter. If the face is badly swollen, make a digital examination, and over the root of the affected tooth you will find a spot about the center of the swelling where it seems to be spongy, appearing to hold the impress of the finger. Take a clean, sharp, cycle-shaped lancet, place on the spot, holding the patient’s head firm with your other arm for fear of his moving. ”

“ Although the dentine is not as unchangeable as enamel, but manifests, by becoming firmer or softer, that it is not quite uninfluenced by tissue-changes, yet its caries is not an irritative process that the dentine takes an active part in, but a passive process, and consequently the removal of all diseased portions and the protection of the non-carious part of the tooth suffices to stay the morbid process completely. ”

“ Every woman, and especially every mother, should know the time and order in which the infant teeth come, and, when any of the above symptoms appear, should examine the mouth, and if a gum is swollen and inflamed, should either have a physician lance it, or if this can not be done, should perform the operation herself. A sharp pen-knife and steady hand making incision to touch the rising tooth will cause no more pain than a simple scratch of the gum, and usually will give speedy relief. ”

“ The front teeth are called incisors because they are used to cut the food. The back teeth are named molars because they are used in grinding the food.

Toothache.—Toothache is a common ailment, and yet it can be entirely prevented. A tooth does not ache until it has a hole in it. The tender nerve within gives us warning that it is being hurt. The dentist can stop the ache and mend the tooth so that it will not ache again. ”

“ It is plain enough that ninety per cent, of dental work might have been avoided; just as ninety per cent, of the sickness and premature death in the world is needless and could be prevented. The dentists have made the astonishing discovery that they can alter and enlarge the jaws of any child by simple means and they have found out, moreover, that the teeth themselves and their arrangement are the pattern from which the jaw takes its shape. ”

“ The teeth are composed of very hard bone and enamel. The latter is a substance exceeding in density any other in the body. It covers the crown of the teeth, and is thickest in those parts which are most exposed to forcible contact in mastication; but, in no place, is it more than the twelfth of an inch in thickness.
10. The most common disease of the teeth is caries, or decay, and almost every part of them is liable to be affected by it, but especially the sides of those in front, and the crowns of those on other parts of the jaws. ”

“ It is necessary, therefore, to avoid acting like the ignorant and foolish barbers, who in their temerity do not observe any of the above-mentioned rules, and therefore very often cause the patients great injuries, the least among which is the breaking of the tooth, the root being left in the socket, or else the taking away, together with the tooth, of a piece of the maxillary bone, as the author often happened to see. After the extraction the patient must rinse his mouth with wine, or with vinegar and salt. ”

“ As soon as decay begins in a tooth it should receive the attention of a competent dentist, and where this is done a true tooth-ache never occurs. Where one has been so neglectful as to permit the exposure of the nerve of a tooth, he can only be saved from much suffering by going at once to a dentist. ”

“ The scalpriform incisors of the rodents, already alluded to, have the enamel band on the front face of the tooth; the softer dentine behind wears away more rapidly, keeping the cutting surface bevelled, like the edge of a chisel, while the hard enamel forms the sharp edge. In some instances the enamel is absent altogether and the teeth are composed entirely of dentine, as in the elephant tusk. ”

“ When one or more teeth have appeared in an irregular position and offend the walls of the oral cavity or else the tongue, the excision (resection) of the tooth or teeth must be performed with a pair of strong pincers, whose shape must vary according to whether the teeth are situated externally or internally with regard to the dental arches. But as after the resection there will almost always remain some points or sharp irregularities, which by their presence would continue to irritate the soft parts, it will be necessary to remove these irritating prominences by means of the file. ”

“ It very often happens that the patient cannot indicate exactly which tooth it is that gives him pain, his sufferings being so acute as to appear spread over a great part of the jaw. One cannot, therefore, trust too much to the indications given by the patient as to the point of departure of the pain, and must take care not to extract a healthy instead of a diseased tooth. ”

“ It is certainly possible, by a strong mental effort, to keep pain in subjection during a dental operation. A firmly fixed tooth, under a bungling operator, may be wrenched from the jaw without pain to the patient, if he will only determine not to feel. ”

“ In general, when the permanent teeth are irregular, one or more should be removed. If the teeth are crowded and irregular, in consequence of the jaw being narrow and short, or when they press so hard upon each other as to injure the enamel, remove one or more to prevent their looking unsightly, and in a few months the remaining teeth, with a little care, will fill the spaces. ”

“ If these bones are efficiently exercised during the formation of the teeth—and my remarks apply especially to the permanent set—the tooth-germs will be abundantly flushed with blood, while the ample growth of the jaws themselves will provide the germs with plenty of room in which to grow and to develop, and the more perfect their growth and development the more resistant should we expect them to be to the ravages of caries. ”

“ On the slightest appearance of decay or tendency to accumulate tartar, go at once to the dentist. If a dark spot appearing under the enamel is neglected, it will eat in until the tooth is eventually destroyed. ”

“ Then a deep groove is made in the middle of the upper teeth, crossing them all, and itself cutting through at least one-fourth of the whole thickness of the teeth, so that the enamel is cut quite through, a fact which we Europeans, who are taught by our dentifricators that any damage done to the enamel is mortal to the tooth, find it difficult to believe. ”

“ In early life the jaws should be carefully examined by both dentist and doctor in order to determine whether or not the proper development is taking place. If upper and lower teeth fail to fit well together, extra strain is placed upon certain teeth and the sockets are liable to injury and infection. Faulty development can often be corrected and deformities that interfere with proper mastication and place a strain on certain teeth can thus be avoided. ”
