120 HUNTER ON THE TEETH.
The Cuspidatus and Molares of the Foetus are not formed
so Fast as the lncistyres; they generally all appear nearly about
the same time, viz. about the twentieth, or twenty-fourth month:
however, the first Grinder is often more advanced within the
socket than the Cuspidatus, and most commonly appears
before it.(?/)
These twenty are the only Teeth that are of use to the child
from the seventh, eighth, or ninth month, till the twelfth or
fourteenth year. These are called the Temporary or Milk
Teeth, because they are all shed between the years of seven and
fourteen, and are supplied by others.
OF THE CAUSE OF PAIN IN DENTITION.
These twenty Teeth, in cutting the Gum, give pain, and
produce many other symptoms which often prove fatal to
children in Dentition. It has been generally supposed that
these symptoms arise from the Tooth's pressing upon the inside
of the Gum, and working its way mechanically ; but the follow-
ing observations seem to be nearer the truth.
The Teeth when they begin to press against the Gum,
irritate it, and commonly give pain. The Gums are then
affected with heat, swelling, redness, and the other symptoms
of inflammation. The Gum is not cut through by simple or
mechanical pressure, but the irritation and consequent
inflammation produces a thinning, or wasting of the Gum
at this part : for it often happens that when an extraneous,
or a dead substance, is contained in the body, that it produces a

month after the birth ; the first milk molars at about the twelfth month
the canines at about eighteen months ; and the second milk molars at
about twenty-four months. The first teeth cut are the central incisors
of the lower jaw ; these are followed by the same teeth in the upper ;
and, as a general rule, the lower tooth is cut earlier than the corre-
sponding one above. According to Mr. Tomes, it is not until the child
has attained the age of four and a half years that the temporary teeth
are entirely perfected. He found in a child of four years and one month
that the incisors were the only teeth fully formed. The fangs of the
others were slightly deficient in length, and hollow at their extremities.]
