How can we keep our teeth healthy? First, we ought to visit the dentist twice a
year. He can fill the small holes in our teeth before they destroy the teeth. He can
examine our teeth to check that they are growing in the right way. Secondly, we should
brush our teeth with a toothbrush and fluoride toothpaste at least twice a day - once after
breakfast and once before we go to bed. We can also use wooden toothpicks to clean
between our teeth after a meal. Thirdly, we should eat food that is good for our teeth and
our body: milk, cheese, fish, brown bread, potatoes, red rice, raw vegetables and fresh
fruit. Chocolate, sweets, biscuits and cakes are bad. They are harmful because they stick
to our teeth and cause decay.
