In the 17th century dentists tried to make false teeth again. The problem, however, was not making the teeth, it was keeping them in place. They had to tie each tooth to the one either side of it. Only rich people could afford false teeth which were usually made of ivory, gold or silver. As more and more people wanted new teeth to the rich so that they could buy food and clothing.
