Why do we have teeth?

Teeth bite and chew food so that it is small enough to be swallowed.
Teeth help you to form words so that you can speak properly. You will have noticed that when young kids lose their front teeth, their voices sound quite different.

Spring water

Most Australian spring water is treated to remove particles and disinfected, but it is not possible to be sure that all spring water is safe.
There is no fluoride in spring water (unless it has been specially added), and if this is the only water you drink, you are more likely to get tooth decay. Have a look at the topic Teeth and teeth care.
