Experimental upper set of false teeth, late 20th century.

A set of false teeth made from acrylic reinforced with carbon fibre. Carbon fibre is incredibly hard wearing, but as can be seen, it is black which is not a desirable feature for false teeth. The first false teeth were made by the Etruscans as long ago as 700 BC, but the difficulties of decay and poor fitting did not begin to be overcome until the late 18th century.
