Teeth & bones

This week we've been learning about teeth & bones.

This is Emma's work:

INTRODUCTION
People use their teeth to bite & chew food.
They also help us to say certain sounds.
People have 2 sets of teeth in the mouth.

PRIMARY TEETH
Most babies are born with no teeth showing.
The 20 teeth erupt during the time from 6
months of age to 2 years old.

PERMNENT TEETH
When primary teeth fall out 2 are replaced
by 32 permanent teeth (also called adult teeth.)
During the time 6 to 14 years old. As 2 permanent
teeth forms under the gum & in the jaw bone the roots
of the primary tooth is replacing disolve.
The primary tooth becomes loose and falls out.
The permanent-tooth will fill the space.
