Teeth are a part of the digestive system. They are used for chewing food.
Pronunciation and articulation
Pronunciation
is basically controlled by the vocal cord, but it needs
to work together 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 one 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 a deciduous
tooth is lost prematurely, the adjacent teeth will then
move toward the empty space, leaving insufficient room
for the permanent tooth to erupt. The permanent teeth
may have poor alignment.
