We use our teeth for holding cutting and chewing food, so they have to be strong. The part of a tooth that we can see is called its crown. Below the crown, hidden in the gum, is the root of the tooth. This fixes the tooth firmly into the jaw bone. Most of the teeth is made of hard material called 'dentin'. The crown is coated with an even harder material called 'enamel'. If we eat too much starch and do not clean our teeth regularly, we will get teeth decay. This occurs where small pieces of food are trapped in the teeth. Among the most widespread diseases that affect mankind are diseases of teeth and gums. Yet they remain unattended and neglected. One of the reasons of this neglect is that the disease is painless until significant damage has occurred:
