This is also a very general trouble during pregnancy, and sometimes a very severe one. Like several other sympathetic affections it is very irregular as to its first appearance and duration, some suffering from it most of the time, almost without intermission, while others only have it at intervals, and but slightly. It sometimes depends upon unsound teeth, but is frequently experienced without any such cause, and is then a true _neuralgia_. When it arises from a bad tooth, the pain is usually confined more or less to the neighborhood of the tooth, but when it is neuralgic it extends over the greater part or the whole of the jaw and face, and darts about from one part to another. In true toothache there is also usually more or less inflammation and swelling, while in the most agonizing neuralgia nothing of the kind can be seen. The treatment must be regulated by circumstances. If the pain appears to be kept up by an unsound tooth, it should by all means be extracted, unless the patient be so exceedingly nervous and irritable that abortion is to be feared, in which case the pain must be alleviated as well as it can be, though there is almost as much danger in leaving the tooth in such cases as in extracting it. A few leeches to the gums will sometimes relieve, or a mustard poultice to the cheek, or a blister behind the ear. The stomach or bowels being out of order may also keep up the irritation, and regulating them may materially assist in giving relief. Some persons are relieved by lotions of camphor, or laudanum, and others by washes of cayenne tea, or alum water. In the neuralgic form, when no particular tooth can be found in fault, the treatment must be more general than local. The _Carbonate of Iron Pills_, which can be purchased at the druggists ready made, have frequently an excellent effect; from two to four may be taken at a dose, twice a day, the bowels being kept open, if necessary, by a little tincture of rhubarb. If the pain comes at regular intervals, or intermits, it may frequently be stopped by quinine. _Two_ of the ordinary _quinine pills_ may be taken every _five hours_, for two or three days. If the head feels oppressed by their use, the dose must be lessened to _one_. M. Guillemeau recommends the following to be tried if other means fail, and I have known it to be of decided benefit. Take the whites of _two eggs_, and _two ounces of common black pepper_, in powder, and beat them well together. Spread this on some tow or cotton, and lay it on the cheek. It may be kept on till it causes considerable irritation, and sometimes may be used on both sides. Some females have been relieved by bathing the face in _cold_ water, or keeping _ice_ in the mouth, and others by hot fomentations. It has also been recommended to fill the mouth with cold water, and bathe the cheek with hot at the same time!
