Good teeth help us to chew our food. They alsohelp us to look nice. How can we keep our teeth healthy? Firstly, we ought to visit our dentist twice a year. He canfill the small cavities in our teeth before they destroy the teeth. He can examine our teeth tocheck that they are growing in the right way. Secondly, we should brush our teeth with atoothbrush and fluoride toothpaste at least twice a day - once after breakfast and once before wego 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. Chocolates, sweets, biscuits and cakes are bad,especially when we eat them between meals.
