Teeth are very important for our health. They will be our lifelong friends. So we should learn to protect them at a very young age. Here are some tips：

First，we should eat right.

◆Don't eat too much candy or drink too much cola，or our teeth will go bad easily.

◆Have more cheese，milk and yogurt to make teeth strong.
