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.
