The eye-teeth after a time
begin to make their appearance; and then more double teeth; making in
all twenty-eight teeth, and occupying in their developement from the
seventh to the fourteenth year of age. They are not, however, yet
complete; for between the latter date and the twenty-first year four
more teeth appear, called the wisdom teeth, making the adult set or
permanent teeth to amount in all to thirty-two teeth. It should be
observed, that whilst this is the most usual course in which this set
appear, the line of succession is sometimes different.
THEIR VALUE AND IMPORTANCE.
It would seem almost unnecessary to say a word upon so self-evident a
truth, and yet perhaps the full extent of this statement is not
generally appreciated. It has not, perhaps, occurred to the minds of
all, that upon the right position and arrangement of the teeth the
beauty and expression of the countenance much depends. But so it is;
for however regular and perfect the general features, if the teeth are
irregular or deficient, an unpleasing expression, proportionate to the
extent of the displacement, is inevitably produced. Now every mother
should be alive to this fact, that she may early apply to the dentist
to have any error of the above nature rectified, before it is too late.
