 Excavation of Whitworth's grave in the 1990s revealed the poor state of his teeth, resulting from the dangerous products used in his time to clean teeth.Whitworth, according to Napoleon, was a ""fort bel homme"", and this description is confirmed by the portrait by Sir Thomas Lawrence, an engraving from which appears in Doyle's "Official Baronage".There is a very fine mezzotint engraving of this portrait by Charles Turner.
