Everyone wants to have healthy teeth. When you laugh, you will open your mouth and show your teeth. The healthier your teeth are, the     you feel. Why is that?
It’s     your teeth are important in many ways. Take care of them, and they'll help to take care of you. Strong, healthy teeth help you grow. They also help you speak    . You can take care of your teeth by doing like these:
Brush your teeth twice a day, after getting up and before bedtime. And you brush all of your teeth, not     the front ones. Spend some time on the teeth along the sides and in the back. Take your time while    . Spend at least three     each time you brush. Be sure your toothbrush is soft. Ask your parents to help you get a new toothbrush     three months. Clean     your teeth and dental floss (牙线). It     strange when you do it at first, but soon you'll get used to doing it. Brushing keeps your teeth healthy. You also need to care about  you eat and drink. Eat lots of fruits and vegetables and drink water instead of drinks.
