TIGHTENING LOOSE TEETH 7

instrument downwards, thus causing pain, without
succeeding in removing hard calcareous deposits.
Inorganic and organic acids are to be used—viz.,
sulphuric and hydrochloric, formic, lactic, and tri-
chloracetic.
When acting for some minutes, acids cause decal-
cification or dulness of the enamel.
Influenced by this fact, I endeavoured to dissolve
the tartar b}" prolonged action of a harmless drug
capable of dissolving tartar.
A chemist, Dr. Eichter, has succeeded in making
a preparation likely to fulfil the requirements enu-
merated above. It is enclosed in ampoules, and is to
be introduced along the necks into the pockets.
The liquid at once forms an adherent film, which
contains the active ingredient, distributed, as it were,
in a sponge, and is washed out by the saliva.
After the mouth has been rinsed the remedy begins
its action, which lasts from one and a half to two
hours, the saliva dissolving small quantities of the
substance from the film, and the solution acting as a
tartar solvent.
After a few hours the calcareous deposits are
softened, and may be removed, together with the film,
by means of the usual scalers.
The preparation has a favourable action in gingiv-
itis and pyorrhoea alveolaris, thanks to its disin-
fecting and astringent properties. Besides, it lessens
sensitiveness, and facilitates the painless removal of
tartar.
