When you get your picture taken, everyone says, "Say cheese! Smile!" So you do
— you open your mouth and show your teeth.
When you see the picture, you see a happy person looking back at you. The healthier
those teeth are, the happier you look. Why is that?
It's because your teeth are important in many ways. If you take care of them, they'll
help take care of you. Strong, healthy teeth help you chew the right foods to help
you grow. They help you speak clearly. And yes, they help you look your best.
Why Healthy Teeth Are Important
How does taking care of your teeth help with all those things? Taking care of your
teeth helps prevent plaque (say: PLAK), which is a clear film of
bacteria (say: bak-TEER-ee-uh) that sticks to your teeth.
After you eat, bacteria go crazy over the sugar on your teeth, like ants at a picnic.
The bacteria break it down into acids that eat away tooth enamel, causing holes called
cavities. Plaque also causes gingivitis (say: jin-juh-VY-tis), which
is gum disease that can make your gums red, swollen, and sore. Your gums are those
soft pink tissues in your mouth that hold your teeth in place.
If you don't take care of your teeth, cavities and unhealthy gums will make your
mouth very, very sore. Eating meals will be difficult. And you won't feel like smiling
so much.
Before Toothpaste Was Invented
We're lucky that we know so much now about taking care of our teeth. Long ago,
as people got older, their teeth would rot away and be very painful. To get rid of
a toothache, they had their teeth pulled out. Finally, people learned that cleaning
their teeth was important, but they didn't have toothpaste right away.
While you're swishing that minty-fresh paste around your mouth, think about what
people used long ago to clean teeth:
- ground-up chalk or charcoal
- lemon juice
- ashes (you know, the stuff that's left over after a fire)
- tobacco and honey mixed together
Yuck!
It was only about 100 years ago that someone finally created a minty cream to clean
teeth. Not long after that, the toothpaste tube was invented, so people could squeeze
the paste right onto the toothbrush! Tooth brushing became popular during World War
II. The U.S. Army gave brushes and toothpaste to all soldiers, and they learned to
brush twice a day. Back then, toothpaste tubes were made of metal; today they're made
of soft plastic and are much easier to squeeze!
Today there are plenty of toothpaste choices: lots of colors and flavors to choose
from, and some are made just for kids. When you're choosing a toothpaste, make sure
it contains fluoride. Fluoride makes your teeth strong
and protects them from cavities.
When you brush, you don't need a lot of toothpaste: just squeeze out a bit the
size of a pea. It's not a good idea to swallow the toothpaste, either, so be sure
to spit after brushing.
