Neuralgia.
A great many young ladies from seven to seventy complain about this terrible trouble in some form or another. If it is what we call hemi-crania, engaging, if I may use the term, the whole half of the face and head, it may proceed from a bad tooth, or from what is the worst sort of a tooth anyone could be plagued with—a tooth with one small hole in the side. Have this seen to as soon as the first attack has gone. Probably a clever dentist may be able to fill it for you. Some girls go hurrying away to the dentist at once, have gas, and have it out. Such a pity, for as you get older what a blessing you will find your own teeth!
Thank Heaven, I have never worn a false tooth, but it strikes me the sensation can be far from agreeable. If one uses the toothbrush, with a good disinfectant powder, such as borax or charcoal, followed by a rinse of water tinged red with permanganate of potash (and this is usually sold as Condy's fluid), she will have teeth that will last as long as they're wanted.
But what I wish to tell you here is this: apart from actual decay of a tooth and consequent irritation of the nerve, a girl need never have facial neuralgia, nor sciatica, nor any other "algia" if she but lives in such a way as to make herself hardy as a heather stem. Dinna forget that.
