Teeth play an important role in our daily life.They not only let us eat food,They also help us talk.

Let's talk about the teeth.

（1）The correct ways and steps to brush your teeth.

You must brush your teeth well ,or they will turn black.If you don't take care of your teeth, you will get cavities.

Brush your teeth and gums thoroughly.

You should brush your teeth every morning and night.

（2）What's a cavity?

Cavity. That's the word no one wants to hear at the dentist's office. A cavity (say: KA-vuh-tee) develops when a tooth decays (say: dih-KAZE), or breaks down. A cavity is a hole that can grow bigger and deeper over time. Cavities are also called dental caries (say: KARE-eez), and if you have a cavity, it's important to get it repaired.

But why would your tooth develop a hole? Blame plaque. That's a sticky, slimy substance made up mostly of the germs that cause tooth decay. The bacteria in your mouth make acids and when plaque clings to your teeth, the acids can eat away at the outermost layer of the tooth, called the enamel (say: ih-NA-mul).

If you don't go to the dentist, the acids can continue to make their way through the enamel, and the inside parts of your tooth can begin to decay. If you've ever had a toothache or heard an adult complain about one, it may have been because there was a cavity that reached all the way inside a tooth, where the nerve endings are. Ouch!

Your dentist will carefully examine your teeth and may take X-rays.If your dentist discovers a cavity, he or she can repair it for you by first removing the rotted part of your tooth with a special drill. The dentist then fills the hole in your tooth with a special material. The result is called a filling.

Does it hurt? Sometimes it does, but your dentist can give you an anesthetic (say: an-es-THET-ick). That's a kind of medicine that will numb the area around the problem tooth while you're getting your new filling.

（3）cavity prevention tips.

Though cavities can be repaired, try to avoid them by taking care of your teeth. Here's how:

• Brush your teeth with fluoride toothpaste after every meal or at least twice a day. Bedtime is an important time to brush.
• Brush up and down in a circular motion.
• Gently brush your gums as well to keep them healthy.
• Floss your teeth once a day to remove plaque and food that's stuck between your teeth.
• Limit sweets and sugary drinks, like soda or juice.
• See your dentist twice a year for regular checkups. We hope you'll hear those two wonderful words: "No cavities!"

（4）Tiny Teeth



Unlike your heart or brain, your teeth weren't ready to work from the day you were born. Although babies have the beginnings of their first teeth even before they are born, teeth don't become visible until babies are about 6 to 12 months old.

After that first tooth breaks through, more and more teeth begin to appear. Most kids have their first set of teeth by the time they are 3 years old. These are called the primary teeth, baby teeth, or milk teeth and there are 20 in all. When a child gets to age 5 or 6, these teeth start falling out, one by one.

A primary tooth falls out because it is being pushed out of the way by the permanent tooth that is behind it. Slowly, the permanent teeth grow in and take the place of the primary teeth. By about age 12 or 13, most kids have lost all of their baby teeth and have a full set of permanent teeth.

There are 32 permanent teeth in all — 12 more than the original set of baby teeth. Most people have four teeth (called wisdom teeth) grow in at the back of the mouth when they're between 17 and 25 years old. These complete the adult set of 32 teeth.
