阅读短文, 并按要求完成文后小题。
Teeth are a key part of your body. Strong, healthy teeth help you chew all kinds of foods that help you grow. They help you speak clearly. That's why it's necessary to take great care of your teeth. The following suggestions help you have healthy teeth for life.
One is to brush your teeth at least twice a day, more often if possible. You'd better brush your teeth after every meal, especially a sweet snack, which is the best way to protect against tooth disease（疾病）. It's necessary to clean the front, back and top surfaces of all your teeth.
Another step you can take to protect your teeth is flossing. Floss is a thin thread（丝线）that moves between teeth to remove food that your toothbrush can't reach.
You should pay attention to what you eat. Eating foods that are high in sugar can lead to tooth disease. That's because bacteria that causes tooth disease loves sugar. You can eat fruits and vegetables instead, which are good for your body as well as your teeth.
Healthy teeth will always bring you happiness. Do you want to have white and healthy teeth? Please take care of your teeth!
