Humans have four types of teeth –
3. Pre molars
These are the pointed teeth present in the front. The teeth generally visible when we smile.
These are used in cutting and biting food.
It is pointed and chisel shaped.
These are more pointed than the incisors
They are also used in cutting and tearing of food
In non – vegetarians these are highly pointed as they are required to cut and tear the flesh
pre molars –
the are used for crushing the food, that is, for chewing purposes
these contain 2 cusps and are smaller than molars
these are absent in children
these mark the ends of the jaws
these contain 4 – 5 cusps
these are required for chewing and crushing of food
an adult human being has the following number of teeth
· 8 incisors
· 4 canines
· 8 pre molars
· 12 molars
Thus this was the classification of teeth in human beings. I hope this helps.
