Arfihcfal Teeth a Cheap Luxury-A Machine
for Making Excavating Burs.
1--WE sold 1000. 600 more false teeth last year
than We ever disposed of before in twelve
month, )" said the manager of the greatest den
tai supply establishment in the world TO n STAR
reporter yesterday. 81 don timagine that it was
because people are losing their teeth more rap
idly now than heretofore, although it is unques-
tionably the case that the enduring quality of
the human che wing apparatus has become pro-
gressively less from generation to generation in
this country. 1t is more the fashion now than
il has ever been in the past TO wear false teeth.
partly for the reason that the public has come
to realize what excellent substitutes they are
for real ones. and partly owing 20 the fact that
toothiessness excites much more disgust than il
did in old times when such an affection was
commonly observed and was regarded as una
voidable,
at is very rare to see person nowadays,
whether man or a woman. visiblv disirured
by the absence of teeth. Anybody whose grind
ers fall out will in nearly every case go to q
dental surgeon and procure artificial ones.
They don't cost much. You can geta cornuIete
double set for from SIG up TO $50 Probably
a fashionable dentist will charge you the latter
price. His margin OF profit is considerable in
asmuch as the teeth themselves cost only from
10 to Is cents apiece. Thcy are made OF porce-
lain, of kaolin usually. baked in an oven. For
the plates the material best approved Is rubber.
The handsomest plates are made of celuloid
and they have the advantage of hghtness in
weight. but celluloid does not resist well tho
acids with which it comes into contact in tie
mouth. Aluminium has been tried. but il is
affected by vinegar and salt. as wei as b. other
substances that are eaten. the resdlt being the
development of salt of aluminium. which is
thought to be injurious to the system.
THE ENAMEL.
"The enamel Of artificial teeth is composed of
metallic oxides, and tie finishing processes 20
which they are subjected are so delicate that no
two teeth produced can be made exactly alike
IL point of cOloring. Among all the hundred
of thousands of teeth which we keep in stock
probably no two would match TO absolute per-
lection. But those that are most nearly alike
are put together so that the eye ~ nobody but
an expert would detec. any difference. After
ALL natural teeth exhibit marked dssmilarities

natural and dental surgeons commonly carry
their imitation of nature 30 far as to make teeth
in many instances lo.E more or less defective
the better 30 carry ont the deception. What is
called bridge work consists in inserting a
faise tooth IN n gap between two natural ones in
the jaw, fastening X in place by gold bands
around the adjoining teeth. Gold crowns are
frequently put on old roots nowadays. this de-
vice having the advantage that the crown can
be readily removed at any time for the purpose
of keepiug the root beneath in good condition
The latest important invention i'll the line of
dentistry is machine by which steel excavat-
ing burs are made. Hitherto these delicate liz
tie instruments have had TO be manufactured
by hand You can only perceive how very deli
cate they are BY examining them under a pow

5000. 600 was spent in experiments before he
machine for producing them was successfully
constructed. 1t turns Them out with such
rapidity that they only cost 10 cents apiece
now"
