        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 is some advice for you to take care of your teeth.

        1. 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, too.

        Brush all of your teeth, not just the front ones. Spend time brushing teeth along the sides, and back of your mouth. Brush away from you gums (牙龈), 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 3 months. When you buy your toothbrush, be sure it is a good one.

        2. Learn how floss(用牙线清洁) 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 two teeth. Flossing can help get it out. Carefully move the floss between two teeth, up and down. You’ll need to floss you teeth at least once a day.
