I'm all for individual expression, but this is taking it a little too far. It seems that the latest fashion trend in Japan, is temporary tattoos for the teeth.
While Japan is often on the cutting edge of fashion, this just strikes me as taking things a bit too far.
According to "japantrends.com":
The process of the teeth art is simple and safe enough according to the magazine, chosen items are attached to the tooth by a special glue, using LED light which simply fastens and dries the glue. The “tattoo” is easily removed after a few days (according to the information given at “Heart Dental Clinic” in Minato Ward in Tokyo) and in this way, you can freely design your personal combination and display different and unique smiles whenever you want.
