Teeth
are a part of the digestive system. They are used for
chewing food.
Pronunciation
and articulation
Pronunciation
is basically controlled by vocal cord, but it needs to
work with the teeth to pronounce different sounds
accurately.
Keep
pleasant appearance
Teeth
can keep our facial profile. Without teeth, our face will
look collapsed. If teeth are kept healthy, our appearance
will even be better.
Reserve
space for permanent teeth to erupt
Underneath
each deciduous tooth, there is a developing permanent
tooth. Deciduous teeth reserve space for permanent teeth
to erupt.
When permanent teeth erupt, deciduous teeth will naturally
fall off and be replaced by permanent teeth.
If deciduous teeth are
lost prematurely, the adjacent teeth will then move
toward the empty space, leaving insufficient room for
the permanent teeth to erupt. The permanent teeth may
have poor alignment.

to space loss
