Tartar of the Tteth. — — 151
EFFECTS OF TARTAR.*
Tartar is one of the most injurious agents to which the
teeth are exposed ; it is also the grand cause of the disease in
the gums and sockets, called scurvy in the gum. Mr. Koeck-

* " There are parts of the teeth which lie out of the way of friction,
viz. the angles made by two teeth, and the email indentations made be-
tween the teeth and the gum.
" Into these places the juices of the mouth are forced, and there stag-
nate and deposite a quantity of calcarious matter, which is dissolved in
them, and which is separated from them by exposure, giving the teeth
the appearance of being stained or dirty. If art be not now used, the
incrustation increasing covers more and more the teeth. When it has
increased so much as to touch the gum, (which very soon happens, espe-
cially at the angles between the teeth,) it produces ulceration of that part,
and a train of bad consequences. Often the gums receding from this
matter, become very tender and subject to hemmorrhage.
"The sockets frequently take part with the gums, ulcerate and become
absorbed; so that the teeth are left without support and drop out."
Hunter, page 192.
" Tartar is one of the most frequent causes of the diseases of the teeth.
It acts directly chemically in the destruction of them ; whilst, by its me-
chanical and irritating influence, it is rendered indirectly more destruc-
tive to them, it being one of the most powerful causes of the diseases in
the gums, periosteum, and the alveoli.
"I have seen instances in which whole sets of teeth, of which the
greatest number were perfectly sound, drop out one after another in
consequence of the ravages produced upon the surrounding parts by the
incrustation of tartar. It is in fact from this cause that the most healthy
people of the poorer and middle classes, even those who enjoy the
healthy and salubrious atmosphere of the country not excepted, almost
universally lose their teeth at that period of age, when the digestive
organs begin to be less regular in their functions." Koecker, page 65.
" Nothing is more destructive to the health of the teeth than tartar.
When any considerable quantity of this substance is suffered to collect
about the teeth, the gums become inflamed and swollen, often producing
absorption of the sockets and the premature loss of the teeth." Snell,
page 180.
" Tartar is very injurious and destructive to the teeth ; as the accumu-
lation increases, its effects keep pace with it ; the gums become exceed-
ingly painful, so as to render the ordinary operation of brushing the teeth
almost impracticable, and this inducing a neglect of the common means
of preventing its accumulation, it becomes the unavoidable cause of its
continued increase. Absorption of the gum and alveolar processes is the
next consequence which gradually goes on until the teeth, loosing their
support become loose, and at length fall our." Thomas Bell, page 196.
" Next to caries, nothing is more destructive to the health of the mouth
than tartar."—Fitch on the Teeth, page 377.
