2. Why do we need to brush our teeth? Brushing removes food and plaque from your teeth. Teeth get stained from coffee, cola, cigarette smoke, alcohol, juices and coloured foods. Brushing helps to keep your teeth and gums healthy.

3. What are teeth made out of? Dentin is like bone and is hard. Enamel is very hard, shiny and tough. Pulp is where each tooth's nerve endings and blood vessels are found.
