and bicycle riders who are very ant to
have their teeth broken of short.
The latest and most ingenious resort of
the dental surgeon is "imDlantation, =" i
E., the setting of new teeth into the law
For this purpose real teeth are employed
and not artificial ones Cocaine having
been first applied for producing local
anaesthesia, a hole is drilled in the .aw-
bone, and into this socket a good tooth
newly drawn from somebody's .aw, is set.
If the patient is young and vigorous the
| osseous structure soon closes around it,
and by the time the gum is healed the
tooth is ready for use. 1t should last for
from three to Ten years. In the case Of
an elderly or feeble person it may be fast
ened in place by silver wires passing
around the jawbone.
The root of freshly-eXtracted tooth
is covered with a delicate membrane
called the peri ;ementum," the vitality
of which materially assists the wished for
combining of the tissues Unless the
grinder is directly transferred, the vital
ity of this membrane must be artihcially
reserved. One way of doing it is TO
| graft the tooth temporarily into the
comb of a cock, that part of the fowl be-
ing we'll fed with blood, as may be seen
| from its redness. When wanted for use
IL is cut out Ordinarily the patient is
obliged to wait for a while until the den
fist has a suitable tooth, freshly ex-
| tracted, unless he chooses to hire some
body to sacrifice one.
One of the most important improve
ments in the modern dental practice is on
| the point of being accomplished. IL will
consist in the substitution of porcelain
| for gold in the filing of teeth. For this
purpose piece Of thin pla tinum foil is in
PRODUCED into the cavity and so manip-
| ulated as to take the exact form of the
hole, as if it were intended as a lining.
| Then it is carefully withdrawn so as not
to disturb It's shape. Thus is obtained a
mold from which a porcelain cast may be
made to fill the cavity exactly. This is
secured in place by cement. The trouble
! is that no cement yet invented is proof
against the dissolving power of the fluids
| in the mouth. Accordingly, this process
of ''in-laping," as it is called, must re-
main to great extent unavailable until a
nonsoluble cement shall be discovered.
There is no longer any excuse for
crooked Jaws, inasmuch as dental sur
geons know how to make them STRAIGHT.
This may be accomplished, up 10 the age
twenty years, by simple contrivauces.
One Of them is plate in two pieces united
by spring, which continually exerts a
pressure IN the desired direction An
other device consists of series of wooden
d SKIS, each one to be worn until it no
longer fits tightly, and then to be replaced
by the one next larger. The deformity
of projecting lower jaw is remedied by
a spring arrangement with cap on the
chin and another on the back of the head.
BY this means the jaw is gradually forced
back until it assumes its proper position.
The process is painful of course.
Tho human Jaw has been steadily
growing narrower, so that most people
have not room enough in their mouths
| for the teeth with which nature has pro-
vided them. Many persons are obliged to
have two or four teeJh drawn, to make
room for the rest. The ''wisdoms" being
superhuous for lack of space, nature is
making them of poorer material in every
+ generation. So these third molars," as
dentists term them, begin to decay usu-
ally as soon as they appear, and have to
/ be at once filed or pulled
Artificial teeth cost only Is to Is cents
! each at the manufacturers One maker
! in New York sells 100000 teeth every
year. They are of porcelain. composed
chiefly of kaolin. The enamel is put on
with metallic oxides, the process being so
delicate that no two teeth are exactly
alike in coloring After being finished
thousands Of them are taken together and
matched in shades. There are fifty diff
ferent shades, corresponding to varia-
tions in the coloring of natural teeth
