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 are some tips for you to take care of your teeth.
1. Brush your teeth on the right way.
Brush your teeth at least twice a day-after breakfast and lunch or after sweet snacks, 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 your gums, 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 three months. When you buy your toothbrush,be sure it has soft bristles (毛).
2. Learn how to floss 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 rid of it. Carefully move floss between
two teeth. Up and down. You'll need to floss your teeth at least once a day.
3. Have good eating habits.

sugar before you go to bed can make things even worse, eat lots of fruit and vegetables and drink water instead
of soda.
