False teeth have been found in Italy in human heads that are over 2,500 years old. They were made of bone and set in gold. However,for hundreds of years afterwards,the apparent dental skill of those early people was lost. Without false teeth people looked old before their time,since so many lost their teeth at an early age.
Toward the end of the 17th century,rich people could buy false teeth made from ivory. The teeth were tied together with silk thread,but it was difficult to keep them in the mouth. That was why rich people would rather buy teeth from the poor who would often sell their teeth to buy food and clothing.
Early in the 18th century a French doctor used steel springs to hold teeth in place. However,it was difficult to close one‘s mouth! Late in the same century porcelain (瓷)teeth set in gold were often used to make false teeth.
Although the use of artificial teeth increased,human teeth continued to be used also. In the 19th century,teeth from soldiers killed in battle were made into artificial teeth. For example,teeth from the dead in the American Civil War were sent to England.
By the middle of the 19th century,an American doctor,Claudius Ash,invented a better kind of porcelain tooth made of a special kind of hard rubber.

Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments Would make more efforts.

This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metal and paper. Advertising has helped this process by persuading many of us no only to buy thing we neither want nor need, but also to throw away much of what we do buy.
