Question

    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 teeth clean.

Second, we should keep these numbers in mind.

*2/Day Brush your teeth at least twice a day: in the morning and before bedtime.

*2-3 Minutes Brush for at least two to three minutes every time.

*3 Months Get a new toothbrush every three months.

*6 Months Go to the dentist every six months for a check-up.
