Teeth are important. Strong, healthy teeth help you chew (咀嚼) foods that help you grow. They help you speak clearly. And yes, they help you look best. Here are some tips 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 (点心), too. Brush all of your teeth, not just the front ones. Spend time brushing teeth along the sides and back of your mouth. 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 toothbrush, be sure it has soft (柔软的) bristles (鬃毛).

·Learn how to floss (用牙线清洁牙齿) your teeth.

Flossing is a very important way to keep your teeth healthy. Food may hide (隐藏) between two teeth. Flossing can help throw it away. You’ll need to floss your teeth at least once a day.

·Have good eating habits.

You need to be careful about what you eat and drink. Eating sugar is a major (主要的) cause of tooth decay (蛀牙). Eat lots of fruits and vegetables and drink water instead of soda (苏打).
