1 . (
Anat .)
One of the hard ,
bony appendages which are borne on the jaws ,
or on other bones in the walls of the mouth or pharynx of most vertebrates ,
and which usually aid in the prehension and mastication of food .
[
1913 Webster ]
Note :
The hard parts of teeth are principally made up of dentine ,
or ivory ,
and a very hard substance called enamel .
These are variously combined in different animals .
Each tooth consist of three parts ,
a crown ,
or body ,
projecting above the gum ,
one or more fangs imbedded in the jaw ,
and the neck ,
or intermediate part .
In some animals one or more of the teeth are modified into tusks which project from the mouth ,
as in both sexes of the elephant and of the walrus ,
and in the male narwhal .
In adult man there are thirty -
two teeth ,
composed largely of dentine ,
but the crowns are covered with enamel ,
and the fangs with a layer of bone called cementum .
Of the eight teeth on each half of each jaw ,
the two in front are incisors ,
then come one canine ,
cuspid ,
or dog tooth ,
two bicuspids ,
or false molars ,
and three molars ,
or grinding teeth .
The milk ,
or temporary ,
teeth are only twenty in number ,
there being two incisors ,
one canine ,
and two molars on each half of each jaw .
The last molars ,
or wisdom teeth ,
usually appear long after the others ,
and occasionally do not appear above the jaw at all .
