Bacteria live in your mouth. Some of them eat what you eat. They make other bacteria. Some bacteria produce acid. In your MOUTH? Yes, bacteria produce acid in your mouth.
What happens to the acid the bacteria produce?
If the acid stays on your teeth, it can make holes in your teeth. Here is how it works.
Since the day you were born, different kinds of bacteria have lived in your mouthand in every person's mouth. The bacteria are very, very, very, very tiny. You cannot see them with your eyes.
When you eat and drink something, the bacteria that live on and around your teeth and gums eat tiny bits of the food that is in your mouth. They even have ways to save some of the food to come back to and snack on later!
Some of the bacteria help you stay healthy, but some of the bacteria produce acid that can cause cavities in your teeth.
bacteria live together, in groups called colonies, all around your teeth and
gums. They make some gluey stuff that holds them onto your teeth and helps them
trap very small pieces of food you eat. Have you ever noticed that you can scrape
some white stuff off your teeth when you wake up in the morning or before you
go to bed at night? That stuff is called plaque. Thats where the
bacteria live. Plaque is kind of like a net that helps the bacteria catch and
hold on to food for them to eat.
After the bacteria eat, they produce acid. The plaque holds the acid against the surface of your teeth. The acid can make holes in your teeth if it is held there for a long enough time. When you eat sugary foods, the bacteria make a lot more acid. They also make a lot more bacteria. More bacteria produce more acid. More acid on your teeth can cause more decay.
Now, do you know why it is important for you to brush your teeth and eat healthy, not sugary, foods?
