Teeth are important. Strong, healthy teeth help you chew foods that help you grow. They help you speak clearly. And, they help you look your best. Here are some advice for you to take care of your teeth.
● Brush your teeth the right way.
Brush your teeth at least twice a day after breakfast and before bedtime. If you can, brush after lunch or after sweet snacks（快餐）, too.
Brush all your teeth, not just the front ones. Spend time brushing teeth along the sides and back of your mouth. Brush away from your gums（齿龈）, too.
Spend at least three minutes each time you brush. Play a song you like to help pass the time.
Get a new toothbrush every three months. When you buy your tooth brush, be sure it has soft bristles（鬃毛）.
● Learn how to floss your teeth.
Flossing is a very important way to keep your teeth healthy. Food may hide in places where a toothbrush cannot get to, like the space between the teeth. Flossing can help get rid of it. Carefully move the floss between two teeth, up and down. You need to floss your teeth at least once a day.

Passage 3
A smile will tell people around you that you are a kind and friendly person. However, many people don’t smile because they think they have ugly teeth. For example, one of my classmates, Mike, doesn’t have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others’ teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of them.
Smiling can help you to feel more confidence and make people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh. An Indian doctor called Kataria said that young children should laugh about 30 times a day, while adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now.
