Forget gold teeth, LED lighted teeth are all the rage in Japan:
The new fashion accessories were originally created as an experiment by two Japanese designers and are now being used in a commercial advertising a winter sale at a Japanese clothing store, Laforet Harajuku. They are quickly becoming a sought after accessory.
The LED smiles can easily be affixed to your teeth and glow different colors while you smile. The colors can be changed wirelessly through a computer interface. Of course they work best in the dark.
