170 Tooth Powders.
The very best toolh powders may be prepared from some of
the following substances, and can be obtained in any quanti-
ty of the druggist.
Substances that act mechanically.^-Trepared chalk, pumice
6tone very finely pulverized, Armenian bole, and charcoal.
Astringent substances.—Peruvian bark, orris root, gall-nuts,
and myrrh.
Aromatic substances.—Cinnamon, cloves, and the essential
oils.
Chemical substatices.—Carbonate of soda, and soaps.
Many others might be added to the above, but they are
enough and are to be preferred.
In compounding a tooth powder, the base or mechanical
agents are first to be chosen, and then the other substances
are to be added according to the purpose for which they are
intended. Tooth powders possessing different mechanical and
medicinal properties are required for different individuals.
We will give a few formula as examples: the following is
stance equally soft and simple. If the gums are spongy and lax,
powdered myrrh or bark, maybe added with advantage.' — Thomas
Bell, page 200.
" The best method to effect this, (to keep teeth clean,) is with a brush
and water; should this prove insufficient, powders composed of Arme-
nian bole, prepared chalk, peruvian hark, or charcoal, may be used with
great advantage. The interstices of the teeth may be cleaned by pas-
sing between them a thread of waxed silk, thereby to dislodge whatever
may have collected on their sides." Parmly's Notes to Brown's Den-
tologia, page 174.
" Qualities of Tooth Powders.—Soot acts by mechanical friction,
but not superior to any bitter powder, as bark. &c.—chareoal acts me-
chanically by-its friction : burned bread the same. Gun powder produces
no effect but through the charcoal and nitrue it contains. Alum is a
most mischievous application to the teeth, being the produce of oil of
vitriol and clay. It is a very strong styptic ; but on coming in contact
with the teeth, it is immediately decomposed, the acid uniting with the
teeth. Salt, perfectly innocent, although not serviceable. Nitre, cr
salt-petre, a valuable application to inflamed gums, removing the rough
viscid slime, which, in some, collects over the teeth and mouth ; it is a
useful gargle and does not act on the teeth. Cream of tartar, improper ;
acts on the enamel. Mixtures of soot, salt, soap, &c. &c. remarkable
only for their naueeous qualities."—./. Fuller, page 65.
