Recently, during excavations for the construction of Rio de Janeiro’s metro network, a discovery was made, at least, curious and unusual.

Among the various pieces found, all of them relating to the 17th, 18th and 19th centuries, a toothbrush made of ivory and bone was also found. It’s believed to belong to Dom Pedro II – His Majesty, the Emperor of Brazil at the time.

At that time there might not have been any electric toothbrushes, but at least the emperor was washing his teeth with a custom toothbrush… and he probably would also have a private dentist… emperor stuff!
