Answer:

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.

How You Can Keep Your Teeth Healthy

Kids can take charge of their teeth by taking these steps:

Brush at least twice a day — after breakfast and before bedtime. If you can, brush after lunch or after sweet snacks. Brushing properly breaks down plaque.

Brush all of your teeth, not just the front ones. Spend some time on the teeth along the sides and in the back. Have your dentist show you the best way to brush to get your teeth clean without damaging your gums.

Take your time while brushing. Spend at least 2 or 3 minutes each time you brush. If you have trouble keeping track of the time, use a timer or play a recording of a song you like to help pass the time.

Be sure your toothbrush has soft bristles (the package will tell you if they're soft). Ask your parent to help you get a new toothbrush every 3 months. Some toothbrushes come with bristles that change color when it's time to change them.

Ask your dentist if an antibacterial mouth rinse is right for you.

Learn how to floss your teeth, which is a very important way to keep them healthy. It feels weird the first few times you do it, but pretty soon you'll be a pro. Slip the dental floss between each tooth and along the gumline gently once a day. The floss gets rid of food that's hidden where your toothbrush can't get it, no matter how well you brush.

You can also brush your tongue to help keep your breath fresh!

It's also important to visit the dentist twice a year. Besides checking for signs of cavities or gum disease, the dentist will help keep your teeth extra clean and can help you learn the best way to brush and floss.

It's not just brushing and flossing that keep your teeth healthy — you also need to be careful about what you eat and drink. Remember, the plaque on your teeth is just waiting for that sugar to arrive. Eat lots of fruits and vegetables and drink water instead of soda. And don't forget to smile!

Answer:

Speech on care of teeth for grade 4

Explanation:

Teeth are one of the most important features of our body. Teeth are comprised of hard, bony structures in the mouths of humans primarily used to chew food. Teeth are the body's hardest, most durable organ-long after bones and flesh have dissolved, archaeologists find well-preserved teeth from humans and other animals that lived thousands of years ago.

             Humans use teeth to tear, grind, and chew food in the first step of digestion, enabling enzymes and lubricants released in the mouth to further break down food. Teeth also play a role in human speech-the teeth, lips, and tongue are used to form words by controlling airflow through the mouth. Additionally, teeth provide structural support to muscles in the face and form the human smile.

             Like humans, most animals use their teeth to chew food, although many animals have evolved teeth that perform other specialized tasks. For example, many carnivorous (meat-eating) animals, such as tigers, have developed long, sharp teeth for clamping down on and killing prey. Beavers have chisel-like front teeth that they use to cut down large trees for building dams.

             So that takes us to the next question, Why have our teeth been so important to us as human beings? Thousands of years ago when man was first created, teeth were more important than they are today. Years ago, teeth were not only used for breakdown of food but sometimes for self defense towards other humans. Men and women used their teeth to survive daily life and protect their young. If you didn't have teeth back then, then your chances of survival were slim because teeth were needed to eat to stay alive, fight off enemies, and to talk. If you lost your teeth in battle or hunting, then you were in deep trouble because man was the hunted by all sorts of animals. Teeth in humans did not and still don't grow back like some mammals, such as sharks and beavers.

We can take care of aur teeth by the following÷

1.Brush at least twice a day.

2.Use fluoridated toothpaste.

3.Brush thoroughly.

4.Floss your teeth daily.

5.Limit acidic drinks like soft drinks, cordials and fruit juices.
