The TEETH should be cleaned after every meal with a "TOOTH PRESERVER," (_i. e._ a very soft brush,) and then rinsed with _tepid_ water--_never neglect this at night_;--nothing destroys the Teeth so fast as suffering food to stick between them--those who observe this rule, will seldom have any occasion for _Dentifrices_--_Essences of Ivory_--_Indurating Liquid Enamels_, _&c._ But it is the rage just now with some Dentists, to recommend Brushes so hard, that they fetch Blood like a Lancet wherever they touch; and instead of "_Teeth Preservers_," these should rather be termed "_Gum Bleeders_." Not even a Philosopher can endure the TOOTHACH patiently--what an overcoming agony then it must be to a _Grand Gourmand_!--depriving him of the means of enjoying an amusement which to him is the grand solace for all sublunary cares.--To alleviate, and indeed generally to cure this intolerable pain--we recommend _Toothache and Anti-rheumatic Embrocation_, (No. 567.) Sal Volatile--three parts. Laudanum--one part. Mix and rub the part in pain therewith frequently. If the Tooth which aches is hollow, drop some of this on a bit of cotton, and put it into the Tooth,--if the pain does not abate within an hour--take out the cotton, and put another piece in--changing it every hour four or five times, till the pain ceases. In a general Face-ach, or sore Throat--moisten a piece of flannel with it and put it to the part affected,--rub any part afflicted with Rheumatism night and morning, and in the middle of the day. I have frequently cured old and inveterate Rheumatic affections with this Liniment. INDEX.
