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.

Eat more vegetables and fruits to help clean teeth.

Second, we should keep these numbers in mind.
