1 The right stroke: Use vertical strokes of a soft brush to clean your teeth. This vertical action is similar to the vertical movement you would use to clean the teeth of a comb. This removes all food particles stuck between the teeth. A horizontal movement would not clean the teeth. Once the food particles are removed efficiently, the formation of permanent stains on the teeth is reduced.
2 Use gentle products: Never use tooth powder or salt for cleaning your teeth. They contain coarse particles which will wear away the top layer of the teeth, making your teeth turn yellow.
3 A fruity rinse: Fruits like an apple or a pear have fibre that cleans up any food stuck to the teeth. They lessen the chance of forming those ugly, dark cavities. Having a fruit after a meal is a good idea.
4 Chew gum: Chewing gum is good for you! Its stickiness picks up the food debris from the teeth surface. As you continue chewing, saliva cleans up your teeth further.
